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.

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)

4949028f85 - Bug fix on inter MCBPC table for inter+q. 
- H.263/H.263+ decoder now knows GOB start codes.
- H.263/H.263+ decoder now returns the size of the stream on the first call.
- Added show_bits() functions to see the buffer without loosing the bits.
- TODO: H.263v1 UMV parsing is buggy.
