Jérôme Martinez	14605a0b99	ffv1dec: plane_index is 1 in case of version 4 gray+alpha. Since version 4, plane_index for the alpha plane is 1 in the case chroma_planes is 0. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Diego Biurrun	ca09effb01	ffv1: Drop unnecessary casts and const qualifiers to match function signatures libavcodec/ffv1dec.c:898:36: warning: cast discards ‘const’ qualifier from pointer target type	10 years ago
Reimar Döffinger	8437cc7206	ffv1dec: Avoid unnecessarily large stack usage and copies. Ideally the compiler could figure this out on its own, but it seems it can't. An alternative that would avoid the messy explicit memcpy would be to use a sub-struct for the parts that should be preserved, which can then simply be assigned.

Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	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.
