Description
Currently the function of pressing . (dot) does a step forward but there is no way of stepping backwards. E.g. pressing , (comma), should result in a step backwards.
Especially when analysing movies frame by frame, one should be able to stap also backwards.
Implementing this would complete the stepping functionality.

Hi
I have a close approximation for this.
It uses the FPS to seek backwards one frame.
Of course this fails for some common codecs, since mplayer AFAIK can only seek to key frames. (This is one advantage of mplayer2, which can, btw).
And it will fail for non constant FPS (see bugtracker of mplayer2), but this seems rather esoterical to me.
The use case for me is MSRLE and IV50 AVI's and it works perfectly for them. That was the main point to drop xanim (which had IV50 and step backwards).
Cheers
