[WIP] minimalistic high-perf high-fps camera capture program for Raspberry Pi

Work in progress, not ready for use

Project goal

Build a USB webcam using a Raspberry Pi Zero 2 board with any of the supported camera modules, and utilize the sensor to its fullest potential.

Specifically:

• Support and advertize on UVC all native sensor resolutions and framerates.
• Be as low latency as possible

Current status

• Pi Zero 2 W, HQ camera sensor, 1332x976@120fps MJPEG mode is hardcoded. Works.
• Global shutter camera 1456x1088@60fps mode works at ~45-55fps.

Not implemented yet

• Any controls
• White balance, etc
• Framerate control
• Mode enumeration and selection
• ...

Known issues

• Pi board completely freezes after ~38 minutes on kernel 6.1. In 1 in 10 cases a kernel panic can be seen on UART suggesting memory corruption.
• Pi freezes after ~70 minites on kernel 6.6.
