Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

All the giant companies used ffmpeg
I think you're supposed to read the header files? I have no idea how people write ffmpeg stuff. The only good tutorial I've seen is: https://github.com/leandromoreira/ffmpeg-libav-tutorial

A simple X11+SDL2 animated wallpaper setter and video player
Much of it I learned from An ffmpeg and SDL Tutorial (outdated, but the core idea persists), and from ffmpeg-libav-tutorial.

FFmpeg + WebAssembly
If you are not familiar with libav, ffmpeg-libav-tutorial is a great introduction.

where do I start? Linux embedded development; SoC's. CSI and DSI MIPI
Btw, if you want to encode anything higher than 1080p60 using the Videocore VI, you'll need to use an external library like ffmpeg. There is a good tutorial for ffmpeg too - https://github.com/leandromoreira/ffmpeg-libav-tutorial . This should teach you how to encode the raw video stream you get from the camera into a codec of your choice.

oss-fuzz: https://github.com/google/oss-fuzz :
> We support the libFuzzer, AFL++, and Honggfuzz fuzzing engines in combination with Sanitizers, as well as ClusterFuzz, a distributed fuzzer execution environment and reporting tool.
> Currently, OSS-Fuzz supports C/C++, Rust, Go, Python, Java/JVM, and JavaScript code. Other languages supported by LLVM may work too. OSS-Fuzz supports fuzzing x86_64 and i386 builds.

Fuzz Testing Is the Best Thing to Happen to Our Application Tests
I love fuzzing as a technique and use it quite regularly, but running AFL++ on even a single program occupies all threads of a high end AMD server for weeks. I'm running it locally so only paying for the electricity. If it was a cloud instance it would cost a small fortune. I think this is a reason it is not used more widely.
I will note that Google have a programme for doing fuzz testing on open source projects using computer from their cloud: https://google.github.io/oss-fuzz/

Java Fuzzing with Jazzer compared to Symflower
We will explore how Jazzer is used to automatically generate malicious inputs for Java programs, and how it compares to Symflower, which can automatically generate unit tests to uncover bugs and errors in your code. With the help of Jazzer, many bugs - some of them even in the OpenJDK - were found already. Also, as of March 2021, Jazzer is officially part of OSS-Fuzz, Google's cloud fuzzing engine. It should be noted that Jazzer is a pure "bug detection" utility that finds reproducers for errors in user code. Symflower can do the same, but provides additional functionalities to boost developer productivity, like generating high coverage unit tests and providing test templates for the software developer or tester.

OpenSSL added new C parser code [...] without doing any basic security testing
I find it odd that Google's oss-fuzz didn't find this a long time ago.
