u-bo1b@0w.se	8d1dd5bd50	cinepak: More correct Cinepak decoder. change the treatment of the strip y coordinates which previously did not follow the description (nor did it behave like the binary decoder on files with absolute strip offsets).

u-bo1b@0w.se	4e635e10e2	cinepak: Use correct colorspace. The new code is also faster and more robust. As for the performance: old decoder + conversion to rgb: fps = 2618 old decoder, without converting to rgb: fps = 4012 new decoder, producing rgb: fps = 4502 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Mike Melanson	12d9a36481	Add another special case to the Cinepak video decoder so that it can handle the following file: http://samples.mplayerhq.hu/V-codecs/CVID/bad_cinepak_frame_size.mov This fix works around another work around which handles a different type of odd Cinepak data.

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

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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.

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
