+Source from URL / Live Stream
+-----
+You can use sources from url or live stream in that way:
+
+```json
+...
+        {
+            "in": 0,
+            "out": 149,
+            "duration": 149,

+            "source": "rtmp://srs.discovery.stream/live/stream"
+        }
+...
+```
+But be careful with it, better test it multiple times!
