Hi, there. I'm reviving a mail from 2011... here it is the last of the thread: http://lists.puredata.info/pipermail/pd-list/2011-02/086741.html
I was looking for help to use Gem with v4l2loopback. These mails are the only ones where I found the way to do it (no other place in internet).
After installing v4l2loopback kernel module, I did what IOhannes said:
you should be able to use [pix_record] with v4l2loopback. just do:
- create [pix_record]
- check at the console whether it prints something like "[pix_record]:
backend #1='V4L2'" (this will only happen the first time you create a [pix_record] object for hygienic reasons)
- if so, continue
- set the codec to "v4l2" and the output filename to /dev/video1 (or
whatever your loopback-device is). something like [codec v4l2, filename /dev/video1, record 1( should do the trick.

Now, there is /dev/video1 (also, /dev/video0 from Webcam). But, when I try to open that device with VLC, I got this error:
[0x7fed08000e28] v4l2 demux error: not a video capture device [0x7fed08000e28] v4l2 demux error: not a radio tuner device [0x7fed08000e08] v4l2 access error: not a video capture device [0x7fed18003898] main input error: open of `v4l2:///dev/video1' failed
I tried to open with Blender, videoOnTexture, but the texture is black. There's no error messages.
What am I doing wrong?
I have Pd-extended 0.44.0-extended-20130808, Ubuntu 14.04. I don't know how to know Gem version.
