Public bug reported:
I use livestreamer and mpv to watch streaming content on Twitch. The
stream is very slow to start and takes at least thirty seconds until the
video plays.
I have included the terminal output from livestreamer, but the problem
also happens when when opening a http stream with mpv by itself.
