Juanjo	ef5b1b5a7e	- Advanced Intra Coding (AIC) support for H.263+ encoder, just DC by now. - Bug fix H.263+ AIC tables. - Warning fixes. Originally committed as revision 431 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	d7e9533aa0	fixed msmpeg4 infinite loop if buggy stream rewrote quantizer fixed bias (+10% compression/quality for h263 like codecs) qscale=1 support mpeg1 intra frames looks far less blocky added codec_id field Originally committed as revision 423 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	cd8e5f9637	* fixes problem with -funroll-loops and buggy gcc compiler Originally committed as revision 421 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	ba8d0be99d	rounding bugfix Originally committed as revision 409 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	9dbf1dddbd	mpeg2/mpeg4 dequantizer support (c & mmx) mpeg1 dequantizer optimizations Originally committed as revision 404 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
Michael Niedermayer	3bf43d42ed	mpeg4 mpeg quantizer support Originally committed as revision 381 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
Juanjo	43f1708f8b	- Added PSNR feature to libavcodec and ffmpeg. By now just Y PSNR until I'm sure it works ok. Also it's slow, so use it only when you _really_ need to measure quality. - Fix libavcodec Makefile to enable profiling. Originally committed as revision 314 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Juanjo	9e15ad28bd	- Bug fixes in H.263+ Advanced INTRA Coding decoder. - H.263+ should be able to decode streams with AIC now :) Originally committed as revision 311 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Juanjo	d140623fc4	- H.263+ decoder support for Advanded INTRA Coding (buggy) Originally committed as revision 310 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	d6a4c0b111	* some modifications to allow gcc to compile same code for -fPIC - introduced MOVQ_WONE, MOVQ_WTWO * unrolled put_pixels_clamped_mmx * added .baling where the jump address would be compiled on odd address * added some testing code to disable all these routines (for time measurement) Originally committed as revision 308 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
