Player stops streaming randomly and goes blank

[danstiner]

I've noticed while starting load testing that the player inevitably stops streaming after some time. It's not completely random, it seems to be related to data not flowing fast enough, the stream stops and the video goes blank. Sometimes it resumes correctly after a second but sometimes it never comes back.

I think that because this seems to happen more when more concurrent streams are running, or especially when the are CPU spikes from starting several streams at the same time.

Also because of these logs I see in the web console when a stream stops:

Janus slow link: undefined
Remote track muted: Event {isTrusted: true, type: "mute", target: MediaStreamTrack, currentTarget: MediaStreamTrack, eventPhase: 2, …}
Removing remote track
Janus remote stream

(Opening here because the player repository does not allow issues)

I think the next step is better logging, both internally in the player codebase and wiring up to the video element event handlers to understand what's going on.

I suspect this is related to #33

My working theory being that HangupMedia gets called (but not respected) and we just keep shipping packets, causing some confusion.

Thanks for looking so quick, that sounds promising.

I'd argue this is a ship blocker. Sometimes things work fine but often my streams cut out after just a couple minutes due to this and the only recovery right now is to refresh the page. That's a very bad user experience.

Agree yeah, I have the HangupMedia bug marked ship blocking (hopefully they're dupes)
