d8cf5aea49 optimized the normal bitstream writer, its faster than the alternative one on p3 now ... lets hope its at least not slower on p4 & k7

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.

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.

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.

3cb32e3d1f PATCH by Rik Snel <rsnel@cube.dyndns.org>

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)
