Video RTSP streaming

[mvp-cwlin]

I am trying to use the video-output node to stream an image topic to QGroundControl using RTSP, but keep getting error messages like "streaming stopped, reason not-linked (-1)". I have also tried using rtp and save directly to file, it all worked, but I really want to use rtsp. Anything I am missing?

while the previous ros node is running, 'video-viewer' was used on the same machine to check if it is receiving anything.
