[MPlayer-dev-eng] Enhancement patch for slavemode

[Arpi]

Hi,

search the archive, this was discussed a lot recently
the way you implement this outpit is a big hack and may not work with given
fileformats. do it clean way or do not do.

> 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
