Webcam and mic in SSH
I am using localhost ssh to forward a gnome session to xephyr, as shown here. The only difference is that I'm forwarding user A's session while logged into the main session of user B. Both are local users. Is there a way for me to access webcam and mic in xephyr?
Using client's hardware or using server's hardware are both fine as, in my case, they are the same

Re: Webcam and mic in SSH
Do I get you correctly: you wanna use webcam and microphone over network?
If so, then for microphone your solution is pulseaudio, and for webcam there's v4l2loopback+ffmpeg streaming.
uname == latest pf-kernel

Not network. I've started a Xephyr session in which I want to use webcam. The session runs using `ssh user@localhost`

Then nothing prevents you from using it directly.

The Xephyr session doesn't detect the mic as it is essentially a SSH session

Re: Webcam and mic in SSH
That depends on whether your application relies on pulseaudio or not. If it does, pulseaudio should be started. Otherwise, direct access via ALSA may just work.

Thank you. The same problem with webcam remains

Re: Webcam and mic in SSH
If the webcam cannot be accessed, this might be a permission issue. Check whether the user has an access to /dev/video* files.

Re: Webcam and mic in SSH
For audio: https://wiki.archlinux.org/index.php/Pu … _same_time
(If you use ~/.config/pulse/default.pa, you'll have to .include the default similar to this: https://wiki.archlinux.org/index.php/Pu … default.pa )
For video, I suggest you add your secondary user to the video group or give the users permissions with sudo setfacl to "/dev/video#" As far as I know, systemd-logind only allows the first active user access through its automatic rules.
