we use an undocumented youtube api that is "hidden"
but used by the youtube.com video player to get video info
to get all the information about a video and give it to you
this means that we have the same view as a signed-out user
we can't download age restricted videos for this reason
the way youtube scales videos down is by separating the audio
and video track so it's a audio WEBM and a video MP4 file played at
the exact same time. if we wanted to use these, we'd have to use ffmpeg
and host these videos by separate, which would be a pain to do.
an advantage of this is that we can give you the audio tracks without having
to do all the work ourselves.
nice try richard stallman
it's not open source
why wont you just SHUT THE FUCK UP FOR A SECOND
