My only guess is that because ffmpeg seems to exit, the device that is recognised maybe not picked up??? Error opening input: Immediate exit requested

Tried also to manually configure

streams:
  windows_webcam: 
    - ffmpeg:device?video=0#video=h264
  S2: 
    - ffmpeg:device?video=0#input_format=yuyv422&video_size=640x480#video=h264#hardware

but these are not visible either

Maybe go2rtc can't access FFmpeg.
