Describe the bug
I've attempted to use USB to mirror the camera on my smartphone to the Windows 11 laptop.
scrcpy --video-source=camera
Regretfully, after running the command, I am receiving the given error.

The command scrcpy --list-cameras also outputs the same error.

It seems that my search for issues on Github wasn't very successful. Thank you, the scrcpy-server build functions perfectly for me.
