Michael Niedermayer	8f4b176c55	avcodec/dvbsubdec: add some basic av_log debuging support Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	deadcf5e71	huffyuvdec: implement trick for BGR Before: 179436 decicycles in rgb, 32735 runs, 33 skips Stripped object size: 23188 After: 154861 decicycles in rgb, 32738 runs, 30 skips Stripped object size: 22736 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	11b4703813	huffyuvdec: implement trick When the joint table does not contain a valid entry, the decoding restarts from scratch. By implementing the trick of jumping to the 2nd level of the individual table (and inlining the whole), a speed improvement of 5-10% is possible. On a 1000-frames YUV4:2:0 video, before: 362851 decicycles in 422, 262094 runs, 50 skips 182488 decicycles in gray, 262087 runs, 57 skips Object size: 23584 Overall time: 8.377 After: 346800 decicycles in 422, 262079 runs, 65 skips 168197 decicycles in gray, 262077 runs, 67 skips Object size: 23188 Overall time: 7.878 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

James Almer	3ab4f96a91	motion-test: force C functions for the reference C context It was instead using the highest available asm functions, which completely kills the point of being a reference C context. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Timothy Gu	108dec3055	x86: dsputilenc: convert hf_noise_mmx to yasm Signed-off-by: Timothy Gu <timothygu99@gmail.com> Several bugfixes by: Christophe Gisquet <christophe.gisquet@gmail.com> See: [FFmpeg-devel] [WIP] [PATCH 4/4] x86: dsputilenc: convert hf_noise_mmx to yasm Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Janne Grunau	896a5bff64	arm: check if AS supports .dn Move the GNU as check before the arch specific asm checks since the .dn check requires gas compatible assembler. Disable the VC-1 motion compensation NEON asm which is the only part using that directive. The integrated assembler in the upcoming clang 3.5 does not support .dn/.qn without plans to change that. Too much effort to implement it while it is rarely used. http://llvm.org/bugs/show_bug.cgi?id=18199.	11 years ago

Diego Biurrun	880e2aa236	Remove all Blackfin architecture optimizations Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.	11 years ago
Diego Biurrun	b88cc5cca1	bink: Rename BinkDSPContext member so as not to clash with BlockDSPContext	11 years ago

Michael Niedermayer	d41a4a765b	avcodec/mjpegenc: allow encoding amv with height % 16 != 0 when strict -1 is set This should make it simpler for users to test if such videos work Suggested-by: carl Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Reimar Döffinger	6d695d7acc	Fix nonsense non-mod16 AMV flipping code. It is obviously nonsense since it produces wrong results or even crashes (crashes should be encode-only though).

Anton Khirnov	ed39cda029	flacenc: send final extradata in packet side data	11 years ago
Anton Khirnov	0957b274e3	lavc: add an option to enable side data-only packets during encoding Some encoders (e.g. flac) need to send side data when there is no more data to be output. This enables them to output a packet with no data in it, only side data.	11 years ago

James Almer	ac1077ab50	lavc/dsputil: add missing vsad8 and vsse8 functions the mpeg encoder would try to use them if vsad or vsse were selected for frame_skip_cmp and frame_skip_threshold or frame_skip_factor were set to values != 0 example: "ffmpeg -i INPUT -c:v mpeg2video -skipcmp vsad -skip_threshold 1 -f null -" Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
