Latest daily broke UDP video (working in QGC 4.0.6, not working in QGC 4.0.11)

Hi Daniel,

Upon update from previous version (4.0.6, probably sometime early November) to latest 4.0.11 daily (both android and windows are effected). Our video stops working, just says “waiting for video”.

Previously used daily and current stable works just fine with same settings.

Settings in none working(latest daily):

Working in stable:


2020-12-17 build works for me on android. Try to restart stream once QGC is listening or change resolution.

  1. You do know streams and devices vary?. What are you streaming (from)? What format? rtsp? udp? what? It is not the entire video system that is broken, it is a particular type of stream.
  2. It is not about restarting, we tried everything, as indicated once rolled back it starts to work, so it is definitely a change in QGC
  3. It is an issue across multiple units with the same setup.

I am using UDP h.264 like in your screenshots. Streaming from raspberry:
gst-launch-1.0 rpicamsrc bitrate=800000 awb-mode=tungsten preview=false sharpness=100 sensor-mode=5 ! video/x-h264, width=640, height=480, framerate=30/1 ! h264parse ! rtph264pay name=pay0 pt=96 ! udpsink host= port=5602

But as I mentioned, not all bitrates and not all resolutions work.

Where did you mention this?
Yes, I think that is the case that not all bitrates and res work. We cannot change the resolution.
