You don't need any "glue" code, mplayer itself can do all you need. I have not 
checked this in Windows, but here in linux this patch works perfectly well. 
At least with mkv demuxer, others seem to have problems with -sb.

The magic constant is the offset of video in the resulting binary, it could be 
anything larger then the mplayer binary size. Changing it does not change the 
size of the binary, so you will need to recompile mplayer just once to get it 
right.
