 If you want to use **RTSP** transport - the command must contain the `{output}` argument in any place. On launch, it will be replaced by the local address of the RTSP server.

 **pipe** reads data from app stdout in different formats: **MJPEG**, **H.264/H.265 bitstream**, **MPEG-TS**.

+Pipe commands support two parameters:

+- **killsignal**: Signal which will be send to stop the process (default: sigkill)
+- **killtimeout**: Time in seconds after the process will killed with sigkill (default: 5)
+
+The **killtimeout** parameter is only relevant if **killsignal** is not sigkill.
