# Now that Youtube has gone completely nonfree, we need some way to watch it
# with a full FS stack, don't we?
#
# Tor is now optional (but recommended nonetheless), and yad is used instead of
# zenity to provide the GUI. It's a small download (<100kB) and has much better
# handling then zenity, although it doesn't always come by default.
#
# Note: requires mpv to work. Also, tor{socks} is crucial lest you not
# want to anonymize yourself
#
# CREDITS:
# Thanks goes to Jookia for pointing out how to do this in a neat one-liner:
# mpv --keep-open=yes --ytdl-format "bestvideo[protocol!=http_dash_segments][height<=?480]+bestaudio/best[height<=?480]" "$1"
#
# Basically all I did was wrap a GUI around the whole thing.
