I'm trying to transmit my screen using ffmpeg and v4l2loopback, more when running the commands:
sudo modprobe v4l2loopback devices=1 video_nr=2 card_label="Camera Loopback"
and
ffmpeg -f x11grab -framerate 30 -video_size 1366x768 -i :0.0 -f v4l2 /dev/video2
chrome does not detect the device in: /dev/video2, I tried everything to make it work, but chrome does not detect it, I tried to add the filter:
-vf format=pix_fmts=yuv420p
but still nothing.
Chrome: 87.0.4280.66 (64bit)
OS: LinuxMint 19.3
v4l2loopback: 0.12.3
If anyone can help me, thank you in advance!.
Load videodev module:
sudo modprobe videodev
Load v4l2 loopback:
sudo modprobe v4l2loopback devices=1 video_nr=2 exclusive_caps=1 card_label="ExternalWebCam"
Important Details: Chrome, only accepts buffers in yuv420p pixel format, which makes a lot of sense, since the cameras have this pixel format as standard.
Use example:
ffmpeg -f x11grab -r 30 -s 1366x768 -i :0.0+0,0 -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video2
This command, stream the screen to /dev/video2 device, created by v4l2loopback
