Juanjo	43f1708f8b	- Added PSNR feature to libavcodec and ffmpeg. By now just Y PSNR until I'm sure it works ok.

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
