Michael Niedermayer	24e3f44aed	EC: fix dest index for non 420 chroma. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
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

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in.

Diego Biurrun	e5d2bdec11	Add rectangle.h #include for fill_rectangle(). Originally committed as revision 22877 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c28112fab6	Make sure the EC code does not attempt to use inter based concealment if there is no reference frame available. (this can happen because the EC code will attempt to use reference frames even for I/IDR frames) Originally committed as revision 22732 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fc4a2d1e8c	Change ref_index structure so it matches how its organized in h264. Also revert the related error concealment hotfix. Originally committed as revision 22640 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
