@martijnbraam I'm debugging low framerates with main camera on PinePhone. I can't convince libcamera to get more than 8.5 fps. So I tried megapixels, I could not clone from main site, so I have:

519570a267ad8e70c16f45c7157ac195f57c4c66 (HEAD -> master, origin/master, origin/HEAD)
Remove calibration data for PP front camera (MR 34)

Preview looks nicely smooth, but AFAICT it is around 7fps. I'm on mobian. Any idea of possible causes / how to debug that?

@pavel the sensor doesn't support decent framerates on full resolution, that's why Megapixels sets it to 720p mode for the preview. There it can request the 30fps mode for the smooth preview (and it helps a lot with processing frames for the live view as well :)

If none of that works I guess it's the order of setting resolution and framerate that's the issue. I remember a while back there being a code that set the rate multiple times just to be sure :P

@martijnbraam Ok, I'll keep looking. So far it looks to me like even megapixels are limited to 8.5 fps on mobian I'm using.
