Use ffprobe to gather metadata #3
Description
Turns out, ffprobe can gather metadata on shoutcast v1, v2, and icecast streams in a semi-similar pattern. We should use ffprobe -i <url> -show_entries format_tags -of default=noprint_wrappers=1 -show_streams -v error
This is what we get from an icecast server:
> ffprobe -i <url> -show_entries format_tags -of default=noprint_wrappers=1 -show_streams -v error
