+# Extract screenshots
+
+You can periodically extract screenshots from available streams by using FFmpeg inside the `runOnReady` hook:
+
+```yml
+pathDefaults:
+  runOnReady: |
+    bash -c "
+    while true; do
+      mkdir -p $(dirname screenshots/$MTX_PATH)
+      ffmpeg -i rtsp://localhost:8554/$MTX_PATH -frames:v 1 -update true -y screenshots/$MTX_PATH.jpg
+      sleep 10
+    done"
+```
+
+Where `10` is the interval between screenshots.
