Video Codec in 100 lines of Rust
I discovered this while looking for more resources for my own codec from scratch project: https://github.com/kevmo314/codec-from-scratch

QOIR: A fast, simple, lossless image file format
> For example, if you have a relatively wimpy camera that streams out a 160×120 grayscale image, it might be fun to see how far you can push something like combining:
I'm typically not one for self-promo but I did this with video and you can get 90% compression with exactly those three basic steps. RGB -> YUV420, delta encoding, then basically-upgraded-RLE. You can find the guide here: https://github.com/kevmo314/codec-from-scratch

pkg-config error
Hey. I try to get WebRTC Pion to work. For that i follow the instructions on pion/mediadevices: Go implementation of the MediaDevices API. (github.com) . I added the x264 codec.

Resources for understanding Pion/WebRTC?
I use the pion/mediadevices package to obtain the screen of a Raspberry Pi as a video stream and then I use pion/webrtc to share that to a web server.

Share video feed (camera, screen, file, etc.) from ffmpeg to web(rtc)
Note that there are a lot of tunings that you may need depending on what your latency tolerance and picture quality tolerance is. I would recommend following FFmpeg's streaming guide [0].
If you are trying to stream desktop, camera, and microphone to the browser, I would recommend pion's mediadevices package [1].
