Question

I try to use Mediamtx on my Raspberry PI 3 with an USB Camera

wget https://github.com/bluenviron/mediamtx/releases/download/v1.9.0/mediamtx_v1.9.0_linux_armv7.tar.gz

with this yaml config

paths:
  cam:
    runOnInit: ffmpeg -f v4l2 -i /dev/video0 -pix_fmt yuv420p -preset ultrafast -b:v 600k -f rtsp rtsp://localhost:$RTSP_PORT/$MTX_PATH
    runOnInitRestart: yes

I get the error below
