Hi Csongor(@nygma2004), Nice that you join the discussion. All ideas and proposals are welcome... - Until now I considered the **Exec node** a bit too generic for doing specific ffmpeg stuff, so I have above only compared all existing Ffmpeg nodes. But I must admit that the code of [node-red-contrib-visio-ffmpeg](https://github.com/NGRP/node-red-contrib-viseo/blob/master/node-red-contrib-ffmpeg/node-ffmpeg-command.js) looks very similar to the [Exec node](https://github.com/node-red/node-red/blob/master/nodes/core/core/75-exec.js), so I assume it is derived from it some time ago ... - Had never heard about **avconv** before. Seems that avconv is started as a fork from ffmpeg in 2011, based on internal conflicts in the team. But some years later it has been replaced by ffmpeg again in [Debian](https://lwn.net/Articles/650816/). Anyway I have tried both programs on the same rtsp stream, and in my test avconv was slower (20% more CPU usage): - When I use the two streaming parameters from you youtube video, I only get 3 messages with buffers. And then the stream stops: - And I payed Raspberry foundation for an MPEG hardware license, and now the hardware encoding is enabled: Bart --- _[View the full topic](https://discourse.nodered.org/t/how-to-display-cctv-camera-in-dashboard-rtsp/5860)._
