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

e1c2a5a0a8 - Add reget_buffer() function to AVCodecContext
- Add default reget_buffer implementation in libavcodec/utils.c
- Remove AVCodecContext.cr_available, no longer needed
- Remove CODEC_CAP_CR, no longer used
- Add img_copy() prototype to avcodec.h (function from imgconvert.c)
- Rename img_copy() to jpeg_img_copy() in libavformat/jpeg.c to avoid
conflict
- Updated msrle, msvideo1, rpza, smc to use reget_buffer

158c7f059c use lagrange multipler instead of qp for ratecontrol, this may break some things, tell me ASAP if u notice anything broken
quality which was 1..31 float is now a 1..FF_LAMBDA_MAX int, and FF_QP2LAMBDA * qp can be used to convert to the new range
