2f30a81d19 CONFIG_WIN32 implies MinGW and Cygwin and possibly more, so use just

39a64e3023 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.

d705e4a6bb (f)printf() is disallowed in libavcodec, compilation will fail now if its used, except that codecs which where added after the printf->av_log change which did ignore av_log() and used prinf are now silent and wont print anything, they should be changed to use av_log, i could do that, but its better if the orginal developer decides which AV_LOG level each message should get

9c3d33d67f multithreaded/SMP motion estimation 
multithreaded/SMP encoding for MPEG1/MPEG2/MPEG4/H263
all pthread specific code is in pthread.c
to try it, run configure --enable-pthreads and ffmpeg ... -threads <num>
the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c
