How can I send a virtual camera to Genymotion or Android Studio Emulator in Ubuntu?

I created a virtual camera using v4l2loopback and ffmpeg. The command I use for ffmpeg is: ffmpeg -re -l oop 1 -i vin.png -vf format=yuv420p -f v4l2 /dev/video2

vin.png is the image I want to stream to the webcam and /dev/video2 is the virtual webcam I created with v4l2loopback. The virtual webcam works and I can see it e.g. with onlinemicetest.com/webcam-test. I'm using the Genymotion emulator with the newest Android API (I tried 7.0, 8.1 and 10.0) on Ubuntu 20.40. Genymotion detects the virtual camera but only displays a dummy image: Wrong dummy Image from Genymotion I also tried (and would prefer to use) the android studio emulator. But I can only select Webcam0 in the configuration of the device camera and that points to the real integrated camera and not to my virtual webcam.

I don't need to use ffmpeg, but I do need to use a tool that lets me control which image to stream from the command line.

Is there a way to solve this? Many thanks in advance!

Update 17.11.2020: The Genymotion support answered me, that they plan to support virtual cameras in the future. They might be ready to add this in mid 2021.
