Michael Niedermayer	70d54392f5	lowres2 support. The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	903ccf71b7	error_concealment: Check that the reference is not NULL In normal picture decoding this does not need to be checked but as error concealment is run in the case of errors the availability of references is less certain. This may be fixed differently at some point so that all references are always filled in before the EC code, in which case this should then be changed to an assert() Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	3732c48304	error_concealment: Use previous pictures motion vectors when the current ones have been lost. Looks better for some cases, worse for others, overall not much difference. Its more correct though. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Multiple Authors	a811ec7cb5	Merging branch 'ffmpeg-mt/master' Just some cosmetics & comments, the only functional change "error_resilience: use s->last_picture for accessing last MVs." Is so buggy that it needs a full rewrite, guess -1.0 PSNR loss wasnt enough for ronald to realize there was a problem.	14 years ago
