Arpi	60e575acc8	using Juanjo's way to pass forced type - especially as I_TYPE/P_TYPE defines aren't exported in the public interface, and the flagged method matches the way as qscale forcing work Originally committed as revision 366 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Michael Niedermayer	44eb495128	divx5-gmc support q-pel mc support neither is totally bugfree yet though :( Originally committed as revision 320 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
Michael Niedermayer	2b9ab1d54a	fixing msmpeg4 decoding if fps < 16 (i thought it was a indicator for the ext header, its the fps indeed) Originally committed as revision 313 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	8257bf0534	* eliminating duplicated code from MPV_common_end * simplified indexing Originally committed as revision 305 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
Michael Niedermayer	17592475b3	alternative bitstream writer (disabled by default, uncomment #define ALT_BISTREAM_WRITER in common.h if u want to try it) Originally committed as revision 295 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
Juanjo	81401c1fbc	- Fixes on RTP and GOB headers for H.263. - RTP callback system implemented for H.263/H.263+. - Bug fix on DC coefficients of H.263. - H.263 decoder now returns PTS on picture number. Originally committed as revision 292 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Arpi	3cb32e3d1f	PATCH by Rik Snel <rsnel@cube.dyndns.org> this includes the range for quantized dct coefficients in dct_quantize() (-1023...1023) Originally committed as revision 291 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Arpi	80e103d04c	PATCH by Rik Snel <rsnel@cube.dyndns.org> this patch enhances the jpeg header writer. It can be asked to omit quantisation and huffman tables and it can write different horizontal and vertical sampling factors. (the last thing is useless for libavcodec itself (because libavcodec only handles YUV420P at ecoder level), but the values are initialized so that operation of libavcodec is not impaired) Originally committed as revision 290 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
