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.

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
