I end up with an end-to-end latency of around 800 milliseconds about esp32-cam-fpv

Hi
I don't know what could be going on honestly. It looks like something on the PI side - it's buffering a lot of frames for some reason.
The GL errors could be relevant for this.
I cannot debug this on my side as I don't have time ATM, but I'll check with the first opportunity.

Regarding the mouse, it's probably an issue on the ImGUI -> SDL interaction, where it doesn't register the mouse as a valid input device. Probably trivial to fix if you can debug the issue.

Hello ! I am getting the same kind of error (Video_Decoder line 161), black appears with a few control sliders in a corner. I see a frame rate updating for a few seconds then I have a sigHandler message in the terminal. Have you managed to fix it ?

…. Have you managed to fix it ?

No, I haven‘t.

I managed to compile and setup the pi to debug this issue, I will check tomorrow in detail.
