I'm not big-brained enough to use cameras on Linux, so I decided to
write my own camera stack (based on a real story).

The libobscura experiment exists to find out what a point-and-shoot
API abstracting Video4Linux should look like. It has its roots on one
hand in the Librem 5 project, where I wrote some 70% of the camera
stack, and on the other hand in libcamera, which I found too
difficult to use.

You think controlling a modern camera is easy? Think again. Between
pixel formats, depths, media entities, pads and links, sensitivity,
denoising, phase detection, shutter lengths, DMAbuf, OpenGL, feedback
loops, requests, and statistics, there's enough opportunities to get
lost in the detail.

Thankfully, Prototype Fund thinks I'm up for the challenge, so they
are funding me through libobscura in order to get lost, and maybe
find something in the process.
