High framerate support for OV7251

[elfowl]

The datasheet for the OV7251 says "30,60,90Hz implemented on VOXL, sensor supports up to 120Hz".
But https://docs.modalai.com/voxl2-camera-configs/#image-sensor-configurations only mentions 640x480 @ 30 as supported setting. I ideally want to run the sensor at 120Hz. Can you clarify what frame rates are currently possible and what it would take to make it run at 120Hz on VOXL2?

You can see voxl-camera-server configuration here: https://docs.modalai.com/voxl-camera-server

We have OV7251 running up to 88FPS stable. We'll add 90 and 120 at some point later this year.

@Chad-Sweet Thanks. Can you give me some idea on what this would involve? Does that require modifications on the voxl-camera-server, on the ov7251 driver, or something else?

@Chad-Sweet or to ask in a different way: is it possible for VOXL2 users to influence the sensor behaviour at all or do we just have to wait for a potential announcement?

@elfowl currently, we have to use a proprietary Qualcomm toolchain to generate camera binaries... we would need to add this setting. Our goal is to open up this area such that we can all customize as needed but we don't have this functionality yet. The framework we are using is in general setup for phone manufactures to add a sensor or two to a phone to known locations, so we are kind of hacking it to allow folks to add numerous types to up to 6 locations, which involves removing some onion layers
