[PD] How to use /dev/video2 virtual video device in GEM

[Bart Koppe]

Hi,

I use /dev/video2 to get a mjpeg live stream into PD.
With pix_video I can open my webcam, but when I open the virtual video 
device (/dev/video2) i get an error, i guess todo with the fact that 
it's not a real webcam:

error: Cannot open '/dev/video2': 25, Inappropriate ioctl for device
GL: invalid enumerant--

Is there other ways to get it fixed in GEM?

With pdp_v4l i can open the virtual device, but I want to try it in GEM, 
mostly because GEM is better documented, I need to add several jpeg/png 
pictures on both sides of that stream.


Thanks..

Bart
