The Craft recipe for Okular includes phonon, but no backend. KStars includes 
phonon-vlc (to be able to play .ogg notification files). After copying the 
simpleplayer demo of phonon to the bin folder of KStars I could play the sound 
of a video with simpleplayer, but the video display stayed black. Maybe the 
video codec is missing.

So, the first thing to do would be to add phonon-vlc as dependency of okular in 
craft. Or some other backend. There seems to be an outdated phonon-ds9 (for 
DirectShow), but it does already fail at cmake.

There doesn't seem to be a Craft recipe for gstreamer and therefore also none 
for phonon-gstreamer.

Regards,
Ingo
