I’m running the latest firmware on my herelink (updated last night), and can’t seem to get the video latency to a useable level for a rover application. I’ve tested with both a Foxeer Box 2 and a GoPro Hero4 - and they both give about 260ms (average) latency (typically varies from low 200’s to over 300). The system is advertised as being capable of latency as low as 110ms - what am I missing? Are there settings buried somewhere that I need to adjust to drop the latency?
I’ve toggled the “1080P” option in the video stream options in QGC, but that didn’t appear to change anything. I’ve turned off the “EIS” in the Foxeer camera and set it to 1080/30, though I’m not sure if the latter actually changes anything with the HDMI out.
To clarify the term “useable” latency above - at 250-300ms I find myself wandering back and forth as I drive, trying to battle the latent correction/over-correction.
I didn’t measure the latency before the update, but it doesn’t appear to be any different (just qualitatively by the look/feel, anyway).
