2014-01-06cavsdec: check ff_get_buffer() return valueAnton Khirnov
Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
2013-10-13cavs: Check for negative cbpLuca Barbato
Sample-Id: 00000647-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-10-13cavs: Return meaningful error valuesLuca Barbato
2013-10-04cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun
2013-09-16cavsdec: Make sure a sequence header has been decoded before decoding picturesMartin Storsjö
Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
2013-03-26lavc: Rename avpriv_mpv_find_start_code after moving out from mpegvideoMartin Storsjö
Also move the declaration to internal.h, and add restrict qualifiers to the declaration (as in the implementation). Signed-off-by: Martin Storsjö <martin@martin.st>
2013-03-13av_log_missing_feature() ---> avpriv_report_missing_feature()Diego Biurrun
2013-03-08lavc decoders: work with refcounted frames.Anton Khirnov
2013-01-23Drop DCTELEM typedefDiego Biurrun
It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2012-12-30cavsdec: export picture type in the output frameAnton Khirnov
2012-12-30cavs: deMpegEncContextizeAnton Khirnov
It does not use any of the mpegvideo infrastructure, just a few fields from the context. Fixes a segfault with the emu edge flag, since emu edge buffer is now allocated as a part of the frame buffer allocation and cavs calls ff_get_buffer() directly, it does not use mpegvideo buffer management. Fixes a memleak of the last frame.
2012-12-30cavsdec: cosmetics, reformatAnton Khirnov
2012-12-05lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov
It's got_frame, not data size
2012-12-05lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov
It will be useful in the upcoming transition to refcounted AVFrames.
2012-10-18avcodec: Rename avpriv_frame_rate_tab to ff_mpeg12_frame_rate_tabMartin Storsjö
This table doesn't need to be shared with libavformat any longer. Add mpeg12 to the name to make it less ambiguous, while renaming it. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-10-09Restructure av_log_missing_feature messageDiego Biurrun
Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.
2012-09-29cavsdec: check for changing w/h.Michael Niedermayer
Our decoder does not support changing w/h. Fixes CVE-2012-2777 and CVE-2012-2784. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Anton Khirnov <anton@khirnov.net>
2012-09-07cavsdsp: set idct permutation independently of dsputilMans Rullgard
CAVS uses its own idct so using dsputil to set the permutation is fragile. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-08-26cavs: Move inline functions only used in one file out of the headerDiego Biurrun
2012-08-26cavs: Move data tables used in only one place to that fileDiego Biurrun
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-07-30Improve descriptiveness of a number of codec and container long namesDiego Biurrun
2012-04-06cosmetics: Align codec declarationsMartin Storsjö
Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-03-08avs: fix infinite loop on end-of-stream.Ronald S. Bultje
The codec would keep returning the last decoded frame if the stream contains B-frames, since it wouldn't clear that frame from the list of frames to be returned to the user. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2012-03-02Replace AVFrame pointer type punning by proper struct member assignments.Diego Biurrun
2012-03-02Replace AVFrame pointer casts by proper struct member accesses.Diego Biurrun
2012-02-16mpegvideo: Add ff_ prefix to nonstatic functionsMartin Storsjö
Signed-off-by: Martin Storsjö <martin@martin.st>
2012-01-08cosmetics: drop some pointless parenthesesDiego Biurrun
2011-10-20lavc: use avpriv_ prefix for ff_frame_rate_tab.Anton Khirnov
It's used in lavf.
2011-10-20lavc: rename ff_find_start_code to avpriv_mpv_find_start_codeAnton Khirnov
It's used in lavf.
2011-08-11cavs: fix some crashes with invalid bitstreamsMans Rullgard
This removes all valgrind-reported invalid writes with one specific test file. Fixes http://www.ocert.org/advisories/ocert-2011-002.html Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.
2011-07-11Eliminate FF_COMMON_FRAME macro.Diego Biurrun
FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.
2011-05-02Replace deprecated FF_*_TYPE symbols with AV_PICTURE_TYPE_*.Stefano Sabatini
Signed-off-by: Diego Biurrun <diego@biurrun.de>
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-31Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini
is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk

2009-04-13Rename bitstream.h to get_bits.h.Stefano Sabatini
Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
