FFmpeg.AutoGen

I've been making a video editor for fun using C# and WPF (MVVM pattern). It can't actually render to a file yet... I'm kinda just writing it to help me learn more about WPF. I hope you like it anyway :D
It's been a while since I messed with this stuff, but FFmpeg.AutoGen it's pretty good once you get a few wrappers set up to abstract away all the ugly API calls.

MAUI and FFmpeg
I would recommend you take a look at https://github.com/Ruslan-B/FFmpeg.AutoGen which provide thin wrapper for FFMPEG for dotnet. Because this is thin wrapper, you probably have to teach yourself a bit on FFmpeg APi which is a pain. Maybe you can try other libraries which do not claim mobile support, I think you just need native DLL to make other project works.

Help porting this code to ffmpeg 5.1.2?
I have some problems with outdated methods like "avcodec_decode_video2", currently frame splits to three horizontally and turns into black-white, i can't provide my code now because im not at pc but it really same to https://github.com/Ruslan-B/FFmpeg.AutoGen/blob/master/FFmpeg.AutoGen.Example/VideoStreamDecoder.cs, it not related to C# because i using FFmpeg.Autogen (unsafe bindings without any wrapping)

Using FFmpeg to convert only a range of bytes instead of the whole audio
https://github.com/Ruslan-B/FFmpeg.AutoGen is great, but quite tricky to use. Basically you'll need to create an AVFormatContext with a custom AVIOContext (pb field, see libavformat docs). This IOContext contains the read() and seek() functions, which you'll create using avio_alloc_context(). For the seek() implementation, just make a new request with Content-Range for subsequent reads. After everything is set up, you can just seek based on a time code using avformat_seek_file().

Production example of TPL Dataflow
We used libav directly with FFmpeg.Autogen, with some manual tweaking to certain structures that allowed us to inject proprietary ad timing metadata (not my decision, that came from higher up). Gave me a great excuse to learn how .NET interop works.

It actually uses the native FFmpeg C API directly (libav) instead of the command line tool, with FFmpeg.AutoGen.
