Hi, since COVID-19 forced everyone to dig up old webcams, I thought I'd share my "universal" workaround (sorry it's a clunky one): Step 1 (one time): sudo apt install v4l2loopback-utils Step 2 (redo after reboot): sudo modprobe v4l2loopback devices=1 exclusive_caps=1 Step 3 (before starting a video call): ffmpeg -vsync 2 -f v4l2 -i /dev/video0 -pix_fmt yuv420p -f v4l2 /dev/video1
Notes: * In the above Step 3, /dev/video0 is the "problematic" webcam and /dev/video1 the newly created loopback device. You can check which is which with 'v4l2-ctl --list-devices' (after installing v4l2-ctl with 'sudo apt install v4l-utils') * I recommend letting ffmpeg run in an open terminal during the video call, and stopping it with CTRL-C when finished (so that the webcam can power down and the CPU is not unnecessarily loaded) * What all this does: simply spoken, the problem is that some old webcams expose nonstandard parameters/controls to the software, and not all programs can deal with that. This solution makes a "virtual webcam" with bog-standard properties. The ffmpeg command streams the output from the real webcam to the virtual webcam. * For higher resolution webcams, it may be necessary to add a -s 640x480 or -s 1280x720 or something along those lines to the ffmpeg command. Carefully, because the order of the flags matters. * To use the virtual device in cheese (and possibly other older programs), I believe you still need v4l1compat.so (which solves a different, independent problem). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765058 Title: Regression: 046d:08da Logitech, Inc.
