See http://libdv.sourceforge.net/ LibDV now uses the GNU "Autotools" for building. BUILDING from CVS checkout ========================== Starting with version 0.98, the libdv CVS repository does include the configure script generated by the autotools. Hopefully, this will ease the pain for people who are not inclined to modify their machines installation just to build libdv. If you do have such desire, you can still bootstrap the build with*: autoreconf -i You should check for any fatal errors, noting that you can expect some warnings which are harmless. To build the libdv library and the example player: ./configure make The makefile generated by the autotools is very large, so the more useful targets don't jump out at you. Here are a few. Build a "tar.gz" distribution file: make dist Build a rpm package file. This requires you run as root, or you setup your ~/.rpmmacros to allow building rpms without root: make rpm Clean up objects and binaries: make clean Clean up including files generated by autotools, which should return the working directory state to be like it as after a CVS checkout: make maintainer-clean * Since libdv 0.103, the boostrap file is considered obsolete. Autoconf now includes the program autoreconf that can serve the same role. NTSC Setup/Pedestal =================== This option has been disabled in libdv due to improper usage. If you are still curious about this topic, see Adam Wilt's DV FAQ: http://www.adamwilt.com/DV-FAQ-tech.html#Setup Luma and Chroma Clamping ======================== ITU-R 601 specifies that the legal range for luma is 16-235 and for chroma is 16-240 regardless of NTSC, PAL, or setup issues. However, some users take advantage of the footroom or headroom below or above these ranges to encode additional information for things such as luma keying. The luma and chroma clamp options permit the range checking to be disabled to preserve the superblack and superwhite.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library.

Increase internal audio buffers to 4 channels to plan for future enhancement. 2002-09-03 Dan Dennedy * bugfix to ignore ntsc setup option for PAL in lib encoder. 2002-07-30 Charles 'Buck' Krasic * libdv 0.98 release. * add configure script to CVS repository, to ease the pain of dealing with autotools version messiness. 2002-07-30 Dan Dennedy * applied patch from Steven Schultz to add cross-platform checks for endian.h. * Reverted YUY2 big-endian code because most adapters expect little endian even on big endian architectures(?). A PCI thing? 2002-07-24 Dan Dennedy * enc_input.c: applied patch from Peter Schlaile for NTSC encoding, and tested and debugged ppm and pgm input filters and encode functions. 2002-07-05 Dan Dennedy * dv.h, headers.c: added dv_encode_metadata() to write recording datetime and timcode. * dv.h, headers.c: added dv_encode_timecode() to write a frame count as timecode. 2002-06-27 Dan Dennedy * YUY2.c:dv_YUY2_init(): clamp y lut to 0..255 when clamp_luma is false. * playdv/oss.c: init audio format in native instead of little endian. 2002-06-19 Dan Dennedy * YUY2.c, bitstream.h, dv_types.h: big-endian fixes by Daniel Kobras * libdv.pc.in, configure.ac: remove glib/gtk, add popt dependencies by Daniel Kobras * libdv/Makefile.am: bump libtool version to 2:0:0 * configure.ac: bump package version to 0.9.6 2002-05-26 Stefan Lucke * apply portability patch of Steven M. Schultz * fix off by one in rgb.c array bounds check 2002-05-23 Stefan Lucke * bugfix for #440048, compile playdv with gtk support 2002-05-22 Stefan Lucke * added clamping for rgb render too. (green speckle bug) 2002-05-22 Dan Dennedy * dv.h: add int dv_get_recording_datetime_tm() 2002-05-21 Stefan Lucke * avoid remaining shared memory segment after playdv crash * avoid decoder crash (bug #231580, #558590 etc.). There are some viewable decoding errors now. * new clamping for NTSC Xv mmx + half high render. 2002-05-19 Stefan Lucke * new clamping and addtitional half high renderer of PAL Xv mmx. * modified format of audio error reporting * additional error reporting of video errors example of messages written to stderr ver 00:01:18.21 2001-11-11 14:26:34 9f a7 37 a8 abf 00:01:40.18 2001-11-11 14:26:56 7f 37 00 12 2002-05-17 Dan Dennedy * apply patch from Daniel Kobras (bug 544185) to fix compile on non-x86 architecture. * add const qualifier to input buffer parameter on dv_decode_full_audio, dv_parse_audio_header, dv_update_num_samples, and dv_decode_audio_block. This makes Kino's Frame::ExtractAudio happy. 2002-05-01 Stefan Lucke * audio error correction: default error reporting is set to: stderr old_file = dv_set_error_log (decoder, stderr) default correction method is set to: DV_AUDIO_CORRECT_AVERAGE old_method = dv_set_audio_correction (decoder, NEW_METHOD); NEW_METHOD = DV_AUDIO_CORRECT_NONE | DV_AUDIO_CORRECT_AVERAGE | DV_AUDIO_CORRECT_SILENCE * updated my old invalid email addresses 2002-04-07 Charles 'Buck' Krasic * Version 0.9.5 * Build fixups for 0.9.5 release. For now, stop using an auxiliary directory (was config). The current release of libtool has a bug where it looks to configure.in for that, which we no longer have, and so it gets terribly confused. Some changes to bootstrap to get the right versions of autotools. This needs more work. Autotools sure can be a pain. 2002-04-04 Dan Dennedy * Fix type mismatch in dv_oss_t.arg_audio_device * Set default playdv audio device to /dev/dsp * Fix build system to include gtk+ cflags and libs only for playdv 2002-30-03 Dan Dennedy * Apply bugfix from Peter Schlaile to ppm_copy_ntsc_c block. * Added reppm.c test utility to test RGB recoding. Recode now tests YUV recoding. Both recode 5 times to evaluate multi-generation loss. * Apply patch #533329 from Erik Walthinsen to remove glib dependencies in library. Still need to modify build. * Added new options to disable luma and chroma clamping. The decoder's YUY2 MMX routines do not yet do any chroma clamping regardless of option. * Added new options to enable addition and removal of North American NTSC 7.5 IRE setup. * Added dv_decoder_free(), dv_reconfigure(), dv_encoder_new(), and dv_encoder_free(). Use dv_reconfigure() to reconfigure clamping options. * Enhanced dv_decoder_new() and dv_encoder_new() to automatically invoke dv_init(). You no longer need to explicitly call dv_init(). * bugfix: offset luma -16 in rgb decoding (See Charles Poynton's Color FAQ). The encoder already properly offsets luma +16 on rgb input; without the -16 luma offset in the decoder recoding in rgb results in a positive luma shift. * Tested decoder thread safetiness to confirm it is thread safe. * Modified dvplay to add option for NTSC setup (default on) for best preview quality. * Updated dvconnect from Peter Schlaile to fix a restore bug and add round robin real-time scheduling. 2002-23-02 Dan Dennedy * Added public (shared object) interface to encoder: see dv.h * Added dv1394.h header to support apps needing to use dv1394 IOCTL interface * Added recode.c test utility * Changed configure.in to configure.ac to invoke proper version of autoconf on Debian * Applied patch from Peter Schlaile to repair encode during build on non x86 architectures 2002-07-02 Peter Schlaile * New dvconnect version featuring - multi-threading and buffer control - new video1394 interface support - underrun picture support * Updated insert_audio to plugin interface * Added dvavi, a small utility to convert DV-AVIs to RAW-DV * Added wide-screen option to encoder * Made the encoder detect PAL/NTSC on /dev/video input * Various bugfixes 2001-10-27 Charles 'Buck' Krasic * Apply bugfix from bug report #448856 submitted by Tristan Dufay. * Apply patch #475394: "Fix for mmx_ok SEGV with broken gcc-fPIC" submitted by David Daney. 2001-06-24 Charles 'Buck' Krasic * Version 0.9 * Apply Stefan Lucke's Xv/PPC/PAL patch. * Move bootstrap to bleeding edge autotools, with checks in bootstrap for the proper versions. Add support for pkgconfig. * Make build more quiet. Fixups for some gcc warnings. 2001-06-24 Daniel Kobras * Fix enc_input.c with non-asm. 2001-06-24 * Important bugfix. RedHat 7.1 gcc was generating invalid code for expression in weighting.c. This was causing video artifacts and crashes. Workaround found by changing the expression gcc was messing up on. * New option for selecting Xvideo port. nVidia drivers have now 2 Xvideo adaptors: `Video overlay' (1 port) and `Video blitter' (32 ports). Matrox G series have a similar option. This patch allows to select any of their ports. 2001-06-05 Peter Schlaile * Added dvconnect. A small utility to grab and send dv data over firewire * Added --no-mmap option to playdv in order to handle pipes correctly * Various bugfixes 2001-04-26 Charles 'Buck' Krasic * Version 0.8 * Restructure source: make subdirectories libdv, playdv, and encodedv. This starts to fix some of the #include problems. * Fix typos: missing #ifdef ARCH_X86 around #include "mmx.h" 2001-04-14 Peter Schlaile * Removed "bttv bug work around". It was my VIA board... * Changed DV_WIDTH in rgbtoyuv to make things more clear and compile on more platforms * need_dct_248 now uses the ratio between field error and error in x-direction. Hopefully fixes encoding of cartoons with hard edges. * --force-dct added. Just in case. * Added updated man page for encodedv 2001-04-07 Peter Schlaile * VLC encoder improvements: static qno tables for 3 passes * audio support for the encoder (plugin system with wav and /dev/dsp support) * renamed build_coeff to fill_macroblock and moved it into the input filter. Wrote specialized mmx copy routines. -> now we _are_ realtime on an Athlon 800 even with 3 VLC passes (static qno tables!) It's time to throw the video recorder away ;-) * New option: --fps : select frames per second if your machine isn't fast enough for the full bandwidth * Interface changes: -t renamed to -v since it gives additional verbose output now. * pgm support for mpeg2dec 2001-03-30 Stefan Lucke * New options (available for Xv only): --aspect ([w|wide|n|normal]) --size (10 .. 100) * Reenabled scaling with Xv. Aspect ratio is keept constant when --aspect option is specified. This depends on used window manager too. KDE :-(( , fvwm, enlightment :-) * Changed all render functions to have the same paramerlist * Bug fixes: According to SDL linux FAQ: Applications which support SDL should have an sdl.m4 file in their config. Assembler error messages with encode_x86.S my one does not like div operations with defines. replaced DV_WIDTH/2 by DV_WIDTH_2 2001-03-29 Peter Schlaile * VLC encoder improvements: Now it's more correct for 3 passes (but also slower...), faster for 2 passes. Implemented turbo mode (static qno tables). Hopefully makes the thing finally realtime on an Athlon 800... * Separated out the input and output queue. Build general input and output filter plugin system. Included /dev/video support. * several assembler optimized routines in the vlc encoder added, reorder_88 code is now merged with the DCT postscaler to fill the integer pipelines _and_ the MMX pipelines * renamed encode to encodedv * removed blur function since it doesn't make sense * corrected (?) faster C version of convert_to_yuv 2001-03-19 Charles 'Buck' Krasic * Version 0.7 * Faster C version of convert_to_yuv from Andreas Wacker. * Compilation fixups for building without Xv, and without x86 asm. 2001-03-17 Charles 'Buck' Krasic * Typo fix: swab32 for big endian. 2001-03-09 Peter Schlaile * VLC encoder improvements: Now we do 3 passes and we do it even better than my Sony Camcorder ;-) * need_dct_248 fixes, weighting fixes, seperated out the header writer and a lot more things I've forgotten * NTSC encoding works now really * rgbtoyuv now adapts correctly to the encoding system (PAL or NTSC) 2001-03-05 Charles 'Buck' Krasic * Version 0.6 * Compile fixups to dct.c and encode.c for --disable-asm 2001-03-05 Thom van Os * NTSC encoding fixups. 2001-03-05 Peter Schlaile * Encoder speedups (factor 3 from realtime on my machine, it even beats playdv using gtk display ;-) ) * Fixed stupid need_dct_248() bug * Correct(tm) and faster quantization 2001-02-14 Charles 'Buck' Krasic * Version 0.5 * Integrate patch #103780 "encoder and ppmqscale improvements", from Peter Schlaile (see below) * Bump libtool library version number to reflect dv_init() interface change. * Bug fix for bug #131581: "Initializating multiple dv_decoder_t objects fails". Changed dv_init() to remove dependence on per-stream object, and ignore multiple invocations. * Bugfix from Stefan Lucke for recent PAL breakage. * Cleaner rpm rule in Makefile.am 2001-02-14 Peter Schlaile * Again encoder speedups. * Fixed serious quant bugs (divide != shift!!!!) * Implemented DCT248 AAN version in C and MMX * Integrated use of DCT248 (somewhat experimental. My camcorder apparently uses motion detection for this one...) * General code cleanups * ppmqscale can now shrink pictures * Added a lot of FIXMEs so other people can also improve things (hint, hint ;-) 2001-02-08 Charles 'Buck' Krasic * Add --enable-gprof to configure. Disable SDL by default. Minor fixups in display.c for missing #if HAVE_GTK and #if HAVE_SDL. 2001-02-07 Charles 'Buck' Krasic * Version 0.4. * Cosmetic nit: move to consistent use of C style comments. * Integrate patch from Scott F. Johnston for non-gcc non-x86 architectures. Add untested fixed_multiply to idct_248.c for non-gcc non-x86 architectures. Also disable popt on non-gcc, since our popt code uses gcc struct initialization extension heavily. * Integrate patch from Stefan Lucke for aspect-ratio handling with Xv based display. 2001-02-06 Charles 'Buck' Krasic * Integrate patch from Stefan Lucke for various speedups: - replace pointer dereferences with indexed accesses. - merge 248 idct prescale into 248 quant. - change IEC PAL (420) to generate YUY2 instead of YV12. Is this really faster? If so, I am suprised. I have added a configure option to allow choosing which version to build (YUY2 is default), so I can verify the performance comparison. - Fix to Makefile.vanilla to include util.c in build. - still to do: it looks like there are incompatable versions of popt around. Need to add a configure check to figure out whether filename needs to be declared as a const char *. * Change license banner to read "a free DV codec" instead of "a free decoder". * Add the banner to files that didn't have it. 2001-02-03 Peter Schlaile * Additional encoder speedups and improvements it now also uses popt, can read ppm-streams, can correct wrongly interlaced input pictures. Speedups: we are between 4 and 5 times away from realtime on my AMD K6/400 ;-) slowest part is now the RGB to YUV conversion. * added new program - ppmqscale quality (and quick) ppm scaler.Use it like this cat *.ppm |ppmqscale 720 576 |encode -- - does linear interpolation, next thing is MMX optimization for it. * playdv can now write ppm-streams 2001-01-20 Charles 'Buck' Krasic * version 0.3 * Minor configure.in cleanups. * Add Peter's new utilities to Makefile.am. Minor cleanups for -Wall. 2001-01-20 Peter Schlaile * Made encoder finally work correctly for DCT 88 Inserted META information * Added playdv option: dump frames * added new programs: - insert_audio Audio dub an existing video stream or just copy audio data to DV using insert_audio [wav_file] < * Create a rpm .spec.in file. configure generates the .spec. Makefile.am has a rpm target. Update the README. Add a debug option to configure to control "-g" in CFLAGS. 2001-01-16 Charles 'Buck' Krasic * Add alternate definitions of bitfield structs for architectures with big-endian bitfields. * Add AC_C_BIGENDIAN to configure.in. * Makefile.am tweeks: Add ac_c_bigendian_cross.m4 to AUX_DIST_EXTRA; eliminate duplicate references to header files. * Move bitstream_t to dv_types.h. Remove a few #include "bitstream.h"'s as a result. * Make definition swab32() conditional on WORDS_BIGENDIAN. * New autoconf macro for testing endianness. The stock autoconf test doesn't work with cross-compiling, and autoconf generates a warning to that effect. 2001-01-14 Charles 'Buck' Krasic * Add bgr0 support for kino submitted by Arne Schirmacher . * Add command line option interface to playdv, using popt. * Add more audio code structure; pre-emphasis, speed detection (only play normal speed audio). * Header file re-structuring. Move types to new dv_types.h; enclose declarations in extern "C" for C++ compatibility; replace leading '_' from preprocessor symbols with 'DV_' prefix. * Add exit() handler to avoid Sys V shmem leak with Xv. (Still have to do SDL, and gtk). * Add _GNU_SOURCE define, enabling large (>2GB) file support. 2001-01-08 Charles 'Buck' Krasic * Add preliminary support for audio. New files are audio.[ch] which does the unshuffling, and oss.[ch] which is provides an example of playout via the OSS sound API. 2000-12-27 Peter Schlaile * Integrated MMX/ASM-optimizations into the encoder. (YUV, DCT88, quant) The YUV conversion is 2 bits more accurate than before, the DCT is somewhat less accurate (approximately 1 or 2 bits) so it should be more or less the same as the old C code. Best thing: it is 8 times faster now! 2000-12-21 Charles 'Buck' Krasic * Applied outstanding patch submissions. The major parts included getting the encoder to build again, and autotool'ing the build. This ChangeLog files is far from complete. The log information in CVS is where most of the changes are documented. 2000-05-08 Charlie Krasic * Moved to macroblock at a time color conversion, based on the work of Scott F. Johnston . I rewrote his shuffle code. Partly so I could understand it better (I added lots of comments), and also I did the PAL version too. I decided to leave mapping between dif blocks/segments and superblock row/columns to the parse code. I took his block at a time ycrcb conversion directly, except for making clamp_y lookup based. 2000-05-05 Charles 'Buck' Krasic * New idct code for 2-4-8. It's an integer version, based on an approach like that of the AAN algorithm. Next step will be to MMX it. 2000-04-20 Charles 'Buck' Krasic * place.c: Fixes to 4:2:0 placement.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Here is a another example: /bin/bash ./configure CONFIG_SHELL=/bin/bash Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent configuration-related scripts to be executed by `/bin/bash'. `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. libdv-1.0.0/NEWS0000644000175000001460000000017107273272202010230 00000000000000The best place to keep up with events is to check the libdv mailing lists: http://sourceforge.net/mail/?group_id=4393 libdv-1.0.0/TODO0000644000175000001460000000405707240372513010230 00000000000000[ This file is way out of date ] Performance: - MMX ycrcb conversion to rgb - combine multiplies across weight/quant/idct prescale (?) - parse: - re-arrange data so that coeff blocks are all one big array (alignment + one big memset (mmx!) at beginning of segment) - more efficient bookkeeping (vs current brute force mark and sweep) in second and third passes of parse - still optimize vlc: - combine lookup tables that use the same index: - first level of classes, class_index_mask, class_index_rshift (all indexed by maxbits) - vlc_lookups, vlc_index_mask, vlc_index_rshift (all indexed by class) - sign_mask, sign_rshift (indexed by vlc len) - think about optimizing vlc/getbits interface based on a few observations: - there are three lookups in vlc of the form ((bits & mask) >> shift) are really doing this: bitstream_show_skip(bs,skip,len) // show len bits, beginning skip bits from current position - if we add that interface, and then mmx getbits, this could free registers for better tuning the rest of the vlc lookup code. - note that start and len are bounded to the range 0-16, it might pay to ensure that after flush, show can always count on at least 16 bits remaining in bs->current_word - (there are multiple shows for each flush - eliminates branch in show) - since we parse a whole video segment before we do idcts, we can reserve mmx registers for getbits state for the entire duration of parsing a video segment - note that bitstream state is re-initialized everytime we start a new video segment - mmx version of 248 idct - tune cache footprint: access input and output withouth polluting L1 - get everything working in Windows and use VTune to analyze and improve x86 performance.

Makes things faster but maybe quality drops a little bit. Smaller values mean better quality and larger values mean that you gained some speed. QNO is the quantization number. Larger values mean lesser quantization (15=no quantization at all!) and better quality. You will notice, that there are gaps between the values in the statistics. (Especially if you choose "--vlc-passes=3", where qnos are most likely 15 or 8.) This is normal behaviour since depending on the quantization CLASS some QNOs don't gain you anything and are therefore skipped. There are even codes, that _never_ gain you anything regardless of the chosen classes. CLASS is the quantization class. (Greater values mean higher quantization.) This is used to quantizise larger AC coefficients more than smaller ones. For now, we use the following table max AC-value 0 - 11 | 12 - 23 | 24 - 35 | >35 ----------------------------------------- Y 0 | 1 | 2 | 3 CR 1 | 2 | 3 | 3 CB 2 | 3 | 3 | 3 from the IEC documentation (which is only given for reference.) If you want to improve this, keep the following in mind: * These classes are chosen with the vlc code lengths in mind. There is one code length for codes between 0..11, for 12..23 etc. * You _have_ to use class 3 for AC coeffs. larger than 255, since they can't get encoded otherwise. * It is sensible to quantizise CR and CB values more than Y values. (a) they don't matter that much and b) their bit budget is therefore smaller!) * Larger classes give you finer control over the QNO. * Smaller classes don't have necessarily better quality since you may be encoding quantization noise. That's from the IEC document. I don't know, why they consider picture details with extremely small coefficients as noise, but I agree that large coefficients don't really need all the lower bits. VLC OVERF is the number of vlc_encoder overflows you encountered. That means that some AC coefficients simply aren't encoded! At best it means your picture is somewhat blurred and at worst it has a very psychedelic touch... This should only happen in two cases a) if you use "--vlc-passes==1,2" and QNO 0 b) static_qno since the simple heuristic used can fail easily DCT MODE is the DCT mode chosen. DCT248 is used for fast moving sequences, where the two fields encoded differ a lot. DCT88 has generally better quality. The decision is based on the accumulated differences between the two fields that are larger than a hard coded threshold divided by the same difference in x direction. This makes sure that spotlights are encoded with DCT 88 and not with DCT 248. Something like (sum_i abs(field1[i] - field2[i])) / sum_i abs(block[i+1] - block[i])) > dct_248_limit TODO: - finally go to the library and get the header block specifications ;-) - think of a better way to implement static_qno for 1,3 vlc passes - do correct synchronisation between audio and video (synchronise against system clock since we can't be sure, that the soundcard clock is 100% accurate) - skip frames correctly - find a way to detect NTSC / PAL for video or finally add a force-video-format option. libdv-1.0.0/README.dvconnect0000644000175000001460000000327307436123156012405 00000000000000dvconnect is a small utility to send / capture raw data from / to the camcorder over an OHCI complient IEEE 1394 firewire adapter. It has to be an OHCI adapter since we use the video1394 interface. (It could be done for receiving without it, but for sending it's the only way to go!) You should also install the latest Linux Kernel version (> 2.4.12 I think) since otherwise the necessary patches for DV _sending_ are not included. dvconnect was written to be simple and fast. If it doesn't work for you, you might want to check out dvgrab from Arne Schirmacher... (http://www.schirmacher.de) Since the video1394 interface is not fully developed, you have to do some parameter twiddling to make it work. First, do modprobe ohci1394 modprobe video1394 Then try to catch some test-video data using: dvconnect >test.dv Verify, using playdv if you are in doubt.
