is there a linux program, with a reasonable UI, that can just dump the (video + audio) streams from a webcam? all programs i found seem to insist on re-encoding and my laptop is not powerful enough for that. i suppose i could script something with ffmpeg or VLC or so, but i'd rather have an easy to understand GUI.
edit: i also want to tell the webcam to give me the H.264 1080p 30 FPS stream that it advertises

I am done with my project. Sort of.
What did not work:
- Letting #sane see my document camera with the proper #backend for #v4l because the latter is simply alpha software and development stopped long time ago
- As a direct consequence, I could not integrate the camera into #scanservjs without major changes in this software. A lack of knowledge kept me from doing so.
Right. The trouble with #sane and #v4l #camera|s is its ancient backend
The man-page clearly says:
"This is ALPHA software. Really! Important features are missing and there are lots of bugs. The code is currently only tested on a Linux 2.4 system with a Hauppauge WinTV video card."
http://www.sane-project.org/man/sane-v4l.5.html
Although my setup is configured as sane expects it, the cameras remain inaccessible.
Obviously, "skanlite" (my daily driver) must be using a different way to talk to my cameras
It was fairly easy to understand why v4l was missing. The "debian/rules" file includes the option called "--without-v4l" by default.
Case closed. Let's build again π

https://github.com/umlaeute/v4l2loopback/wiki/WebRTC# #LEE use a #WebRTC based software (#Jitsi etc) but it's not trivial to share pre-recorded #video until they go trough #V4L API , you can also enable a real #webcam and #mic for live Q&A using #OBS ,feel free to improve this wikipage I have created or ask for help https://purl.org/rzr/
Beko Pharm (deprecated)Spent half the night to wrap my head around this and finally getting somewhere with #v4l and #OBSstudio and a loopback device so I can stream this "as fake webcam" over WebRTC in video conferences.
Getting this to run (and smooth!) on #Linux was a PITA. Who would have guessed. And all because I don't want a "streaming" service or some gorram gold membership in a specific video conference "app".
Expect an article!
