Andreas Cadhalpun	226d35c845	escape124: reject codebook size 0 It causes a cb_depth of 32, leading to assertion failures in get_bits. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	8 years ago
Diego Biurrun	b668662939	get_bits: Move BITSTREAM_READER_LE definition before all relevant #includes This avoids the danger that get_bits.h might get indirectly #included before BITSTREAM_READER_LE is defined. Also sort headers into canonical order where appropriate.	9 years ago

Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago

Diego Biurrun	aaf47bcde7	Drop ALT_ prefix from BITSTREAM_READER_LE name. The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Stefano Sabatini	01042d4123	lavc: set defaults in internal codec frames This is required specifically for setting frame->format to -1, otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading the format from the output decoded frame will get misled. In particular fix regressions occurring with the pending vsrc_buffer patch.	14 years ago

Thilo Borgmann	bd7d08e27e	Remove incomplete Doxygen for static decode_frame functions. These functions are not documented for other decoders and should be obvious enough even without Doxygen. patch by Thilo Borgmann, thilo.borgmann googlemail com Originally committed as revision 24237 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	9eb42c272b	Add back previously removed non-existing function params in doxygen comments. Originally committed as revision 24131 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 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.
