| * | avcodec/vp6: select idct based (loosely) on number of coefficients decoded | Peter Ross | 2019-01-26 |
| | | | | | | | | | | | | The VP3/4/5/6 reference decoders all use three IDCT versions: one for the DC-only case, another for blocks with more than 10 coefficients, and an optimised one for blocks with up to 10 AC coefficents. VP6 relies on the sparse 10 coefficient version, and without it, IDCT drift occurs. Fixes: https://trac.ffmpeg.org/ticket/1282 Signed-off-by: Peter Ross <pross@xvid.org> | ||

| * | Make decoding alpha optional for some codecs. | Reimar Döffinger | 2013-09-22 |
| 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.
