done, but  now I always get crashes: the write function is never called, and
additionally av_write_header() for avi, mov and asf segfaults (null ptr 
dereference
of s->buf_ptr in put_byte()).
The other formats (mpeg*) lock forever after a couple of 
muxer_write_chunk().
Michael, what's wrong with this patch?
P.S. I tried both menc:stream.dummy and menc://stream.dummy with the 
same results.

Thanks,
