I needed a jack driven video player to allow me to compose the
soundtrack for a videoclip in MusE. Since there was none available, I
made my own one. I think it is a not so great but adequate example of
the usefullness of jack-transport ;-D
One of the solutions I thought of was that suggested by you: mplayer
slave mode. I don't remember well why I dropped it.
Finally I ended up glueing some libraries to make a very quick hack
that did the job. Don't expect good video performance, nor support of
keyframed video formats, I only spent a couple of days and got what I
needed.
I use it successfully with MusE and ardour. You can check the project
page and a screenshot:
