Whilst waiting for Jiri to reply, I have made a friendly fork here:

    https://github.com/aspiers/ly2video

If he has existing revision control history, we can easily rebase my commits
on top of that when he gets a chance to publish his.

I am hacking on Linux support in the 'linux' branch:

    https://github.com/aspiers/ly2video/tree/linux

although this is not stable and liable to be rebased several times
for the time being.  If anyone else wants to collaborate on this,
please let me know and I'll stop rebasing.

I'm currently thinking that the easiest way might be to use a NLE
video editor to compose the two videos, using my sound track, and
manually tweaking the tempo in Lilypond for the spots where it drifts
out of sync.
