while testing my new Herelink system I faced several Video problems. I used the following setup:
GoPro 4 Black connected to the air unit which was powered by a 2s Lipo.
I faced following ‘issues’:
No video stream in Solex
Bad latency in QGC (between 250-300 ms, values coming from my gut feelings and confirmed by “measurements” using my smartphone stopwatch)
However, after connecting my Autopilot (Cube Orange) to the air unit I was able to start the video stream in Solex with a much much better latency (around 130-150 ms). I havent tried the video stream in QGC with the Autopilot because I have ran out of time… will do it soon.
Maybe it should be stated somewhere, that an autopiltot should be connected for proper video streaming? For me it was not obvious because as I thought video streaming and controlling of a vehicle are two independent features.
