Carl Eugen Hoyos	f32b8130f4	Fix opacity and increase colour dynamics of initial vmd palette.	12 years ago
Kostya Shishkov	31980b6abd	vmd: decode videos with no LZ buffer size provided - they might not need it The buffer is used for an additional pass of frame compression, so videos can be coded without ever using it (and some are coded so indeed, e.g. in Woodruff and the Schnibble of Azimuth game).	12 years ago
Kostya Shishkov	0aed0bfc62	vmd: fix mode 3 decoding	12 years ago
Luca Barbato	701966730c	vmd: drop incomplete chunks and spurious samples Odd chunk size makes no sense for stereo and incomplete chunks are not supported. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Luca Barbato	676da248ca	vmd: refactor the inner decode loop Simplify a little, assume empty frames are acceptable and do not pointlessly reinit the bytestream2 contexts using possibly wrong size values. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Luca Barbato	c8f3cb9119	vmd: return meaningful errors CC: libav-stable@libav.org	12 years ago
Luca Barbato	91a6944e56	vmd: use the PALETTE_COUNT constant uniformly While at it drop useless parentheses.	12 years ago
Paul B Mahol	663794f63d	vmdav: unbreak decoding of samples from game The Last Dynasty This fixes video output with samples HG060808.VMD and HG060810.VMD. Regression since `c0cbe36b18`. While here show warning if decoding is aborted for some reason. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago

Michael Niedermayer	c1f2c4c3b4	vmdav: Try to fix unpack_rle() This fixes out of array accesses The code prior to this commit could not have worked, thus obviously was untested. I was also not able to find a valid sample that uses this code. This fix is thus only based on the description of the format If someone has a sample that uses unpack_rle(), please mail me.

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
