Question regarding webcams and v4l2loopback on Linux
I have a #webcam on a #Linux system and hypothetically, if I were to do the video game streamer thing, I might want to use it to feed video from that camera to two apps simultaneously, namely:
Head tracking software for a video gameFace tracking software for a VTube avatar
But from what I've seen, only one application on a Linux system using V4L2 can get a video stream from a webcam at a time.
The solution I've seen proposed to this problem is v4l2loopback, but none of the sources I've seen bothered to explain how to use it, and the wiki they link to is bare-bones and doesn't seem to explain much either.
Furthermore, I want to be sure that the camera is providing video to these apps at its maximum framerate and not just its maximum resolution, and I don't know how I'd configure this. Or... really anything at all.
Is there any actually relevant documentation I should be reading to solve this problem?
