[FFmpeg-user] Audio captured via AVFoundation is unusable

[FFmpeg]

> With AVFoundation, sometimes audio parameters aren't initialized at start of capture. The OS initializes the audio very shortly afterwards, but ffmpeg uses the parameters advertised in the beginning, which will be incorrect.

This definitely tracks with the behavior I'm witnessing.

That would be excellent, I'd be happy to test it.
