I got now a OpenHD 2.0.0 system working, thanks also to some great help from here and the wiki (and of course the devs).
My goal is to use a GoPro Hero5 black as camera, and I got it essentially working with the well-known DCDZ HDMI-CSI converter card, but I get a huge latency of ca 4 secs or so.
I couldn’t find much info on this topic on the web, so I would appreciate any hint or insight.
I have the EIS disabled, since I found reports that this would be the issue. I also tried a variety of different resolutions, fps, and so on, but didn’t help, always 4secs (I think that this is expected, since I would think that the hdmi negotiates it’s own resolution etc).
What I observe is a large bitrate of ca 10 MBs. It actually frequently runs into the colors, from which I conclude that it’s actually touching the possible limits, which makes me think that this could be the reason for the big delay. If so, which parameters should I tweak?
