about 1/3 faster, no meassureable change in psnr or size and i gues
its even same md5 with my test file but i forgot testing that.

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.
Values between 2 and 6 may yield increasing PSNR (up to approximately
0.04 dB) and better placement of I-frames in high-motion scenes.
Higher values than 6 may give very slightly better PSNR (approximately
0.01 dB more than sc_factor=6), but noticably worse visual quality.
---
Original idea from Michael; patch by me.

anyway, this change decreases bitrate and increase PSNR by ~1.00 on my test file, other files also benefit significantly
