Reimar Döffinger	371e165443	Try to set AVFrame.reference to correct values. I am not sure these new values are correct, not am I sure the semantics are a good idea since we do not seem to make any use of them but they caused a lot of confusion, but this seems to make things closer to matching the documentation.

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

Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil 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.

Reimar Döffinger	f1c5301413	100l, calculate mb_change_bits_row_size from the update width. Originally committed as revision 25661 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Reimar Döffinger	97113c2178	Support mid-stream resolution/format changes for TM1. This makes it easier to fix playback of 24 bit formats. Originally committed as revision 25660 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Reimar Döffinger	2a86d4b905	The 24-bit ydt also should not depend on endianness, since all of it ends up in a single 32-bit pixel. This seems likely to be wrong though, since it is different from the 15 and 16 bit modes and might explain the half-width issue for 24 bit truemotion. Originally committed as revision 24864 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Reimar Döffinger	47af623967	Since the 24 bit format is decoded to endian-dependant BGR32 and not BGR24, do not swap red and blue on big-endian for this format as well. Originally committed as revision 24863 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Reimar Döffinger	751c5093c6	Do not swap red and blue when decoding truemotion on big-endian. Originally committed as revision 24862 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
