Michael Niedermayer	3768445be8	tm2dec: fix overread Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	b7b1509d06	truemotion: forbid invalid VLC bitsizes and token values. SHOW_UBITS() is only defined up to n_bits is 25, therefore forbid values larger than this in get_vlc2() (max_bits). tokens[][] can be used as an index in deltas[], which has a size of 64, so ensure the values are smaller than that. This prevents crashes on corrupt bitstreams. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

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.
