That's part of the C code running on the phone, recording itself. Kinda meta. :)

There's quite a lot of https://en.wikipedia.org/wiki/Vignetting going on. Camera sensors have anti-vignetting circuitry that is supposed to eliminate this, but it needs to be calibrated to each module and maybe even enclosure the module is in.

I recorded this via a C program, but you can do the same via v4l2-ctl command line tool and encode the result with ffmpeg.

Oh man that's cool. I'm working towards that level (C/C++) but coming from JS/Python where you can pretty much "do anything" it's challenging(typing problems in particular eg. array of assorted things of any length).

Oh interesting about the Vignetting will have to read up on that not familiar with the term.

Yeah that's something cool I gotta work with too at some point.

Thanks
