I can capture photos, and see myself moving when preparing to video recording but 1 second after hitting record button the image and cheese itself freezes. It always reproducible.
Lsof shows:
/dev$ sudo lsof /dev/video* 2>/dev/null
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
pipewire 9551 nusch 93u CHR 81,0 0t0 1906 /dev/video0
I'm not sure if pipewire needs to ocupy video device to get mic input. But regardless of the reason cheese should output appropriate error instead of just hanging in some deadlock.
Below the ouput of thread state when its frozen:
