[vdr] Feature request: single frame advance

I don't think this is currently possible but there are occasions when it would be handy to have a 'single frame advance' button from 'pause mode' when playing back a video.

With multi-speed mode enabled, it is possible to step forward at a speed of about a frame every second, or so, but it would be handy to be able to pause a video and then step forward frame-by-frame on a keypress. On some 'normal' video recorders, pressing pause will pause, as expected, and then pressing it again will step forward a frame. Pressing play is needed to start replay once again.

Would this be easy to implement?

Cheers,
