[MPlayer-dev-eng] proposed frame stepping patch

[Felix Buenemann]

Hi,

attached is a patch that adds forward frame stepping using TAB key, when
mplayer is in pause mode. If frame stepping was used, mplayer will seek
one second after resuming from pause to resync audio, this will of
course only work correctly if stream is seekable.

Is it OK, to apply this to cvs?
