Decoding audio from in memory

[xd009642]

So I'm getting encoded audio from a client and transcoding it into a format I use internally. I've been using std::process::Command going into ffprobe, and two ffmpeg instances using piped I/O. It's a bit complicated as I'm also cancelling the 2nd ffmpeg instance if ffprobe reports the audio has only one channel.

I was looking to replace this with using ffmpeg as a library but the transcoding audio example shows opening it from a file so am trying to figure out how to do it just going from RAM?

Oh it looks like I need avio_alloc_context... But I don't see a way to get it currently
