I need to play video files in opengl,for which i installed openml. When i run mlquery, the devices recognised are "nullXcode" and "Wave audio device". No video device was detected.

I have two graphics cards installed, namely "Wildcat4 7210" and "NVidia GeForce FX 5200" cards.
Both these cards do support openml, as mentioned in their respective websites.

How do i get mlquery recognise a video device? Are any openml video drivers available that need to be installed? Please help.

Thanks & Regards,
