Good day Bernhard!!! Thanks for the answer!
mencoder is nearly correct.
You have to use mplayer with the -vo yuv4mpeg output driver and a fifo file:
source avi:
Cache fill: 5,47% (458752 bytes) AVI file format detected. VIDEO: [DIV3] 384x288 24bpp 24,000 fps 945,8 kbps (115,5 kbyte/s)
then
> mplayer -vo null -ao pcm -waveheader file.avi > mkfifo stream.yuv > mplayer -vo yuv4mpeg -nosound -noframedrop file.avi & > cat stream.yuv | yuv2lav -o video.avi
but i have some errors:

You can replace the yuv2lav with anything else.
