hello,
/dev/video2 look to be a V4L device, and not V4L2. so you have to configure pix_video to use V4L driver. a message [driver v4l< should do it (or driver 1, or whatever number pix_video use for V4L) then [open /dev/video2<

Thanks, I now tried, funny to mention that pdp_v4l can read /dev/video2 (virtual video device) and pdp_v4l2 cannot! But I was not clear in my message i think, I just wanted to do the same in GEM. Now I yesterday finally found out how to correctly use pdp2gem, i can just use pdpv4l and use the output wherever i can. Baically i'm a newb in doing a bit of video/images mixing in PD.. ;) Cheers, Bart

did you try pdpv4l2?

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
