Hi there,
Ubuntu 24.04
6.8.0-41-generic
Framework Laptop 13 (AMD Ryzen 7040Series)/FRANMDCP05, BIOS 03.05 03/29/2024
I am using OBS from flatpak (30.2.3) and I can’t get the Virtual Camera to start.
I get the following error:
Starting the output failed. Please check the log for details.
Note: If you are using the NVENC or AMD encoders,
make sure your video drivers are up to date.
Has anyone run into this issue?
Thank you,
-drd
Did you try changing your encoder settings to software/cpu?
Yes,
Settings > Output> (Recording | Streaming) > Video Encoder is set to Software (x264).
Is there any other setting I should change?
What does it say in theblog it mentions?
Can you post the log?

Sure looks like the source you have selected isn’t available. Are you sure you’ve got a working source selected?
Did you install the v4l2loopback module Install Instructions · obsproject/obs-studio Wiki · GitHub ? I don’t think a flatpak would be able to provide that.
Thank you, @Nils:
I followed the instructions:
glxinfo | grep "OpenGL"sudo apt install v4l2loopback-dkms ppa:obsproject/obs-studioBut I still have the same issues:

Very strange.
Is your Logitech brio plugged into your laptop directly? What format and other input source settings are you trying? What bus speed is it reporting with lsusb -t? Does it work with cheese? Is your brio firmware up to date?
Is your Logitech brio plugged into your laptop directly?
No, it goes through an usb3 hub.
What format and other input source settings are you trying?
What bus speed is it reporting with lsusb -t?

Does it work with cheese?
Yes, it does work with cheese.
Is your brio firmware up to date?
No. I have to research how to do that from linux.
Have you tried directly connected to the laptop? Have you tried changing formats, resolution and framerates?
I have tried connecting the camera directly without success.
I haven’t tweaked the resolution/frame rates.
Can you share your resolution/frame rates? Probably not useful because you have different hardware but maybe worth trying.
Thank you for your help,
-drd
I would be trying anything you can. One other user was having similar issues with opencv and updating the firmware on his brio fixed the issue.
You can passthrough it as a USB device probably into a windows VM to do the firmware update.
Not sure if that is relevant but I have other webcams and I have the same problem. Also, one of the scene does not have any cam (is just test and an image) and I still get the same error when trying to load virtual cam.
Maybe try backing up your OBS scenes/profile and then clearing it.
I actually did that when I removed the flatpak installation and moved to the apt repo for installing OBS.
So the same issue? With a brand new profile with just one scene?
Maybe get a log from that simpler setup to post. Might make it easier to figure it out.
Does it work with the onboard webcam?
When setting up the v4l2 source does it show your camera preview working?
Can report that following works fine for me:
OBS Studio Flatpak
sudo apt install v4l2loopback-dkms
And virtual camera works fine for me on PopOS on FW13 AMD
