QXEmbed and gtk_plug made mplayerplug block the whole desktop input, so disable this for now.

Following closely what swtdec-mozilla does, I've now got youtube videos working. Object params are not passed yet, so simply set video size to 440x330.

DBus communication is not working properly, different instances interfere. So the only way to play on youtube is to 'killall knpplayer' and press the play button on the main movie.

No mouse move input select, so auto hiding control panel is not working
