Extract snapshots

You can periodically extract snapshots from available streams by using FFmpeg inside the runOnReady hook:

yml

pathDefaults:
  runOnReady: |
    bash -c "
    while true; do
      mkdir -p $(dirname snapshots/$MTX_PATH)
      ffmpeg -i rtsp://localhost:8554/$MTX_PATH -frames:v 1 -update true -y snapshots/$MTX_PATH.jpg
      sleep 10
    done"

Where 10 is the interval between snapshots.
