 - You can use `width` and/or `height` params, important with transcoding (ex. `#video=h264#width=1280`)
 - You can use `drawtext` to add a timestamp (ex. `drawtext=x=2:y=2:fontsize=12:fontcolor=white:box=1:boxcolor=black`)
   - This will greatly increase the CPU of the server, even with hardware acceleration
+- You can use `timeout` param to set RTSP input timeout in seconds (ex. `#timeout=10`)
 - You can use `raw` param for any additional FFmpeg arguments (ex. `#raw=-vf transpose=1`)
 - You can use `input` param to override default input template (ex. `#input=rtsp/udp` will change RTSP transport from TCP to UDP+TCP)
-  - You can use raw input value (ex. `#input=-timeout 5000000 -i {input}`)
