2014-01-09mpegvideo: drop support for real (non-emulated) edgesAnton Khirnov
Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.

2013-02-15error_resilience: decouple ER from MpegEncContextAnton Khirnov
2013-02-07rv10: improve buffer size check.Anton Khirnov
Check slice count and input buffer size before constructing a possibly invalid pointer, not after.

2012-12-21miscellaneous typo fixesDiego Biurrun
2012-12-05lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov
It's got_frame, not data size
2012-10-08Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov
2012-10-01avcodec: Drop some silly commented-out av_log() invocationsDiego Biurrun
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-04-21Remove lowres video decodingMans Rullgard
This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
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>
2012-03-05lavc: deprecate AVCodecContext.sub_id.Anton Khirnov
In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.

2012-01-25rv20: prevent calling ff_h263_decode_mba() with unset height/widthJanne Grunau
Prevents a crash of VLC during playback of a invalid matroska file, found by John Villamil <johnv@matasano.com>. CC: libav-stable@libav.org

Found by John Villamil <johnv@matasano.com> in fuzzed rv20 in mkv files.

2011-09-19rv10: Reject slices that does not have the same type as the first oneLaurent Aimar
This prevents crashes with some corrupted bitstreams. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-08-17rv10/20: tell decoder to use edge emulationKostya Shishkov
This removes out-of-edge motion compensation artifacts (easily spotted green blocks in avplay, gray blocks in transcoding), for example here: http://samples.libav.org/samples/real/tv_watching_t1.rm Signed-off-by: Diego Biurrun <diego@biurrun.de>
2011-08-09Saner RV1/2 initialisation and RV2 header parsing.Kostya Shishkov
Old version was based on lots of guesswork which had different hacks based on 32-bit version field instead of splitting it into major/minor/micro version. RV2 picture header parser also had a few places where it deviated from binary decoder. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.

2011-02-15Merge libavcore into libavutilReinhard Tartler
It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil. Signed-off-by: Reinhard Tartler <siretart@tauware.de>
2011-01-30Replace dprintf with av_dlogLuca Barbato
dprintf clashes with POSIX.1-2008
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
