Hello, you are missing the -c:v libx264 flag, hence you are using the MPEG-4 video codec instead of H264.

The suggested FFmpeg command is present inside the README:

paths:
  cam:
    runOnInit: ffmpeg -f v4l2 -i /dev/video0 -c:v libx264 -pix_fmt yuv420p -preset ultrafast -b:v 600k -f rtsp rtsp://localhost:$RTSP_PORT/$MTX_PATH
    runOnInitRestart: yes
