asserts to check if assumed conditions really are true

sc_factor support for encoding.

Here's the description I'll add to the mplayer man page:
---
Causes frames with higher quantizers to be more likely to trigger a
scene change detection and make libavcodec use an I-frame (default: 1).
1-16 is a sane range....

10l: bidir_refine didn't save the new mvs. also improve speed.

hmm did i mess the scaling of these up at some point?
anyway, this change decreases bitrate and increase PSNR by ~1.00 on my test file, other files also benefit significantly

quad tree based motion compensation (currently only 16x16 & 8x8 OBMC blocks, but can be extended to other block sizes easily)
different intra block coding (previous was just an ugly hack)
1.8% bitrate reduction -0.01PSNR (foreman@352x288 qscale=8)
1.5% bitrate reduction +0.05PSNR (foreman@352x288 qscale=1)...

nsse weight

Originally committed as revision 3205 to svn://svn.ffmpeg.org/ffmpeg/trunk

change qscale -> lambda for the motion estimation
finetune bit/distortion weighting factor used in motion estimation, the old coeffs where finetuned relative to incorrect mv_penalty tables which where then fixed later but the coeffs where not
this may fix the long standing blocking artifacts, but may also introduce mudding artefacts theoretically, so please tell us if u stumble across any so we can either fix them or export this variable so the user can change it...

reduce dependancy between motion estimation and MpegEncContext
this is practically just a s/s->me./c->/

4mv + b frame encoding segfault fix

Originally committed as revision 2728 to svn://svn.ffmpeg.org/ffmpeg/trunk

fixing twice added offset bug, was triggered by 4mv + sub_cmp != mb_cmp
bug was introduced in version 1.75 (2003-12-30)
this may have lead to a small drop in quality of the 4mv mode, but should have only affected the mbd=0 case
