Using FFmpeg to convert only a range of bytes instead of the whole audio

• FFmpeg.AutoGen

  6 1,267 5.3 C#

  FFmpeg auto generated unsafe bindings for C#/.NET and Core (Linux, MacOS and Mono).

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().
