Absolutely, but then I used ffmpeg to decode the stream and opencv to do the processing.

Just for completeness: some time after we had the long RTSP discussion, there was another question on the forum about storing video as an mp4 file. Since then I don't use _ **Exec** _ nodes anymore for ffmpeg, but always the _ **Daemon** _ node instead (as you can see [here](https://discourse.nodered.org/t/display-camera-ip-in-dashboard-and-store-video-in-raspberry/6349/5)). Because the Daemon node allows you to keep converting (endless) e.g. images to a video file... In that discussion I have added some drawings to explain how the pipes work.
