Kevin,
Got only very few time tonight for Node-RED...
Seems Chrome gives errors when setting a new source (while the other source was still playing), but luckely it is a known issue and the guys from hls.js advice to create a new hls instance every time.
And that indeed seems to work: The version on Github now allows you to set a new source via input messages.*
Example flow:

As you can see in the dashboard, where a new movie is played every time I switch between the 3 sources:
You can choose whatever message structure you like. But I have used msg.topic="set_source" and msg.payload="some url" since that is a common used way to do it ...
Time is up again for today ...
