[MPlayer-dev-eng] Enhancement patch for slavemode

[Stefan Huelswitt]

Hi,
I'm working on a frontend application for MPlayer which uses the
slavemode "-slave" (to be exact, it's the MPlayer plugin for VDR).

The slavemode works very well to control MPlayer, but it lacks
completely any feedback to the frontend (like playtime and
position).

The included patch outputs the information about playtime and
position to the console. The output can be parsed by the frontend
to display a proper progressbar.

I think it could be usefull, to include more things (like total
length of the video, the filename, volumen level), but my
knowledge about the MPlayer sources is to bad to find the need
informations. May be someone else could extend the patch.

It would be nice to have this included into the main source.

TIA
