Finding permanent m3u8

How would I locate a m3u8 for

I doubt you will find a direct m3u link. Looks like they stream to youtube and then use youtube to distribute their stream. That is way more efficient (for them) than directly hosting a stream.

Some quick web searching finds an open-source utility called Streamlink 2.0.0 that is designed to convert youtube livestreams into something more friendly for video playback. The thread below suggests a couple other packages as well that look promising. Regardless, you will need to piece together a discrete solution to make this work.
