That's good. You managed to create a solution that handles both use
cases. I don't fully understand the streaminfo header issue but enough
to get the gist of the problem.
I don't have Tidal but I'll do test on the Flac cue side of things.
FYI - ffmpeg can do a skip (aka -ss ) on a stdin stream - it does so by
just processing all input and waiting until time point before generating
output. Not a real seek but same result. ffmpeg is useful when
workarounds are needed.
