The mplayer output tells me that I have many ARB extensions.
Which ARB extension am I missing?

I finally compiled the latest svn version. But your fragment program now
gives me only a black screen. I attach the output of mplayer.
Also the edgedetect.fp fragment program does not work anymore.
It gives images which are mostly white, with black shapes moving
where persons should be.

./mplayer -vo gl  ~/titel1a.avi
works fine.

Yours,
Johannes
