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
