You didn't forget the QProcess::start(), you did it at if ( !mp->start() ) :)

Try to show up the window first, than you start the mplayer process, you can try to start another app, like kwrite ou anything else :)

If this doesn't work, try to qDebug the QXEmbed winId, and do mplayer by hand, copy and paste with the command :D

And now, try to see if mplayer is running

mplayer -wid option is for outputting video in an existing window,
where the X Window is passed with the wid option.
You assume however that mplayer creates a window that then needs to be
embedded. Which is wrong.
