Ok, thanks for the tip. I'll include it in the docs as soon as I can.

In order to be able to use demux_lavf, don't you need to checkout
libavformat for the FFmpeg project?

Do you happen to know how to tell MEncoder to use a particular muxer
of libavformat?

I think it would be great to be able to mux into NUT as the manpage as
well as the XML doc does mention that NUT is supported, but doesn't
say how to create them...
