Luca Barbato	a90905db2e	ffv1: Assume bitdepth 0 means 8bit CC: libav-stable@libav.org Reported-by: debian/726189	11 years ago

Reimar Döffinger	547c2f002a	Make decoding alpha optional for some codecs. For codecs where decoding of a whole plane can simply be skipped, we should offer applications to not decode alpha for better performance (ca. 30% less CPU usage and 40% reduced memory bandwidth). It also means applications do not need to implement support (even if it is rather simple) for YUVA formats in order to be able to play these files.

Michael Niedermayer	21dc3a3cc2	avcodec/ffv1dec: reorganize thread init/update This moves some allocations to init, reducing possible failure modes in update.
