2013-10-04cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun
2013-09-29pngdec: Stop trying to decode once inflate returns Z_STREAM_ENDMartin Storsjö
If the input buffer contains more data after the deflate stream, the loop previously left running infinitely, with inflate returning Z_STREAM_END. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
2013-05-16Remove commented-out debug #define cruftDiego Biurrun
2013-03-08lavc decoders: work with refcounted frames.Anton Khirnov
2013-01-26pngdec: cosmetics, reformat.Anton Khirnov
Also remove a commented out line.
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.
2012-10-08Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-05-05png: check bit depth for PAL8/Y400A pixel formats.Ronald S. Bultje
Wrong bit depth can lead to invalid rowsize values, which crashes the decoder further down. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
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>
2012-03-08png: convert to bytestream2 API.Ronald S. Bultje
Protects against overreads in the input buffer. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

2012-01-29png: move DSP functions to their own DSP context.Ronald S. Bultje
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.

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>

Patch by Thilo Borgmann thilo DOT borgmann A googlemail com. Originally committed as revision 18421 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.
