Fully spec-compliant NUT tools have not been released, and in fact (I
believe) have not been written, because the NUT spec has not yet been
finalized. One of the MPlayer/etc. developers (Oded Shimon, wasn't it?)
has been writing libnut, a minimal implementation of the format, as the
spec approaches its final form; however, I don't know what the current
state of that code is.

Currently, the only way that I know of to mux to NUT is to use FFmpeg -
and the code involved there may still be based on a now-outdated version
of the spec, which will not be compatible with the final form and so
will not be demuxable by later FFmpeg/libavformat.

I don't remember any specific mention of the former, but I don't know
why it wouldn't be possible. The latter is, of course, very much possible.

I'd be rather surprised if it had been...
