Michael Niedermayer	b8a78f419d	reversing header game MIN/MAX -> FFMIN/FFMAX Originally committed as revision 1184 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Michael Niedermayer	af27aea922	fixing another assert q>0.0 issue caused by variance < 0, this fix allso changes the inter/intra decission very slightly -> all regression checksums need to be updated Originally committed as revision 1122 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Michael Niedermayer	0bfacb95de	fixing q>0.0 assert failure caused by overflow of variance for b frames Originally committed as revision 1120 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Michael Niedermayer	c42612f1b4	clip MVs for direct mode Originally committed as revision 1068 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Michael Niedermayer	693b0e1d66	fixing variance scaling for b frames (messed adaptive quants up) cliping too long MVs in b frames instead of setting them to 0 Originally committed as revision 965 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago

Michael Niedermayer	0d21a84605	dont double check vectors more correct EPZS implementation much faster halfpel ME simplifications / reducing duplicate code 4MV in LQ mode Originally committed as revision 641 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	ff4ec49e64	license/copyright change Originally committed as revision 599 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	9cd3766f6e	- pict_type exported to AVCodecContext - Added real_pict_num to AVCodecContext, it represent the number of the previous encoded frame, usefull when coding with B frames. - Warning fix in motion_est.c Originally committed as revision 484 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	91029be790	much better ME for b frames (a bit slow though) fixed MC rounding for b frames fixed hq mode with b-frames Originally committed as revision 406 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	9dbcbd92e8	fixed mpeg4 time stuff on encoding mpeg4 b-frame enoding support removed old, out-commented ratecontrol reuse motion compensation code between encoding & decoding prefix newly added global functions with ff_ to reduce namespace polution b-frame ME (unfinished, but working) added some comments to mpegvideo.h do MC on encoding only once if possible bugs? ;) Originally committed as revision 403 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	e4986da9ce	- ME setting moved to AVCodecContext/MpegEncContext, no longer a global. - EPZS ME algo used by default. - HQ flag activated for ffmpeg. - Cosmetics ... Originally committed as revision 398 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Michael Niedermayer	ba6802debf	4MV motion estimation (not finished yet) SAD functions rewritten (8x8 support & MMX2 optimizations) HQ inter/intra decission msmpeg4 encoding bugfix (MV where too long) Originally committed as revision 362 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	122546a6d1	seems the old intra/inter decission is slightly better with a threshold, than the new one Originally committed as revision 357 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	174489bdcc	10l (motion_val was uninitilized) 20l (first frame of a gop could be a p-frame sometimes) add hq flag to MpegEncContext Originally committed as revision 356 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Michael Niedermayer	45870f5718	new motion estimation (epzs) not complete yet but allready pretty good :) unlimited mv search range minor bugfix in the mpeg4 header parser reset picture in gop counter if scene change is detected Originally committed as revision 344 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	ce7c56c250	- Added video coding statistics for ffmpeg. Needs more work. - Fixed ME range for H.263+ UMV (32 pix). Originally committed as revision 342 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	9cdd6a24ad	hopefully better bitrate controll Originally committed as revision 334 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	b4dbd87c04	- Minor changes on bitrate control Originally committed as revision 300 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	e03c341ef3	- More work on preliminary bit rate control, just to be able to get an average variance for picture's MBs so we can adjust qscale on the MB layer. Originally committed as revision 294 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	37fbfd0a91	- Now the ME is done for the entire picture when enconding, the DCT/Quantization is done after we have calculated all the MV of the picture. - This is the preamble for a better bit rate control. Originally committed as revision 293 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	2ddeed44a5	(commit by michael) motion-estimation on width/height not divisable through 16 files bugfix Originally committed as revision 279 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
