The FFmpeg Tutorial
The FFmpeg libraries are possibly the worst thing I have ever worked with in my life. I have never been more afraid to use a library than this one. This tutorial is very outdated, eg. `AVPicture`, which is used throughout, is completely deprecated and removed from the library, so you will simply encounter linker errors trying to follow this tutorial.
FFmpeg libraries randomly break themselves, so if you find an answer from a few years ago, chances are it's useless. Want to free an AVPacket? `av_free_packet` is deprecated,. You can use `av_packet_unref` (but there's _also_ a function named `av_packet_free` that doesn't do quite the same thing).
Most questions on Stack Overflow or related platforms have no replies, the library has literally zero documentation, it has very little error handling, which means if you're a bad C developer like me you are required to recompile FFmpeg with debugging information unstripped so you can trace segfaults in gdb.
https://github.com/leandromoreira/ffmpeg-libav-tutorial/ is a better and more up-to-date tutorial than this one.

Error when I install KShare
I found this . I think you need an older version of ffmpeg to use the program, try to write it under the AUR to see if the mantainer is still active and knows the problem.

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Much of it I learned from An ffmpeg and SDL Tutorial (outdated, but the core idea persists), and from ffmpeg-libav-tutorial.

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.

3D graphics on Haskell in 2023
And that's PNG, for reading something more hard to come by, like OggVorbis, there's just one tiny mid-level library called libvorbis. (btw does anyone know a working email of the maintainer of that package, I have an update for that too)

Should raw library bindings drop the namespace prefix?
For context, I have written complete bindings to five different C libraries (freetype2, libvorbis, libspng, al, Chipmunk2D) and the question in the title may very well be the last one I have concerning FFI for quite some time. The question originates from the fact that chiphunk strips prefixes, something no other low-level library I've seen does.
-
Managing structs within low-level FFI bindings
Over the past few years I've written several low-level bindings: freetype2 (actually on Hackage), libvorbis (still waiting for a review on that one) and libpng (package name for that is free, I've just never submitted anything to Hackage myself).
