Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reimar Döffinger	b0c73ba11f	motion_est: fix implicit truncation warnings Patch by Reimar Döffinger and Eli Friedman (independently). Originally committed as revision 24083 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fd8277ffa0	Optimize bidir_refine a bit. compiled code is less tham 1/4 the size. a tiny bit faster Originally committed as revision 22777 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	a69220cce0	Change bidir refine hash code so we only need to perform a single hash calculation for the whole function. negligibly faster (about 0.1%) Originally committed as revision 22775 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2d603902f3	Reduce the size of the bidir refine hashtable from 4096 to 256 and change the hash function to something more sane and simple. about 1/3 faster, no meassureable change in psnr or size and i gues its even same md5 with my test file but i forgot testing that.

Michael Niedermayer	2f16af0667	skip motion estimation and encoding of non direct-0,0 MBs if the next MB is skiped (mpeg4 doesnt allow such MBs and in the past we did ME and encoding until at the end we droped them, so this should be faster though i didnt benchmark it, benchmark welcome) Originally committed as revision 7343 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Steve L'Homme	267f7edcd1	(f)printf --> av_log conversion taken from a patch by Steve L'Homme Originally committed as revision 5127 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Corey Hickey	39a64e3023	sc_factor support for encoding. Here's the description I'll add to the mplayer man page: --- Causes frames with higher quantizers to be more likely to trigger a scene change detection and make libavcodec use an I-frame (default: 1). 1-16 is a sane range. Values between 2 and 6 may yield increasing PSNR (up to approximately 0.04 dB) and better placement of I-frames in high-motion scenes. Higher values than 6 may give very slightly better PSNR (approximately 0.01 dB more than sc_factor=6), but noticably worse visual quality. --- Original idea from Michael; patch by me.

Michael Niedermayer	aacb6acc8a	hmm did i mess the scaling of these up at some point? anyway, this change decreases bitrate and increase PSNR by ~1.00 on my test file, other files also benefit significantly Originally committed as revision 4771 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
