the camera mirroring is really clean I can use it as webcam on OBS stream via capture windows.....is it possible to stream the video captured by camera as v4l2 device? I tried to combine the command for both function and receive this

Does it work with a lower resolution?

scrcpy --video-source=camera --no-audio --v4l2-sink=/dev/video2 -m1024

Since the error is on the device side, it does not seem related to v4l2. Does camera mirroring work at that resolution without v4l2:

scrcpy --video-source=camera

?

It works! Thanks! Yes, the camera mirroring works by itself, streaming video with 3840x2160 resolution. I can push up to 1920x1440 with v4l2
