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

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