Check current state of affairs re:native controls and LIVE content

[ismena]

Currently when playing LIVE content, we set the timeline duration to an arbitrary large value (2^32) to allow seeking.
However, I saw that a LIVE stream played through hls.js supports a reasonable seeking/timeline experience with native controls.
We should check if browsers made any progress on handling LIVE content and see if we might be able to provide a more decent experience with this.

Thanks, that's helpful. Looks like it's available in Chrome and Firefox, but not yet Safari. I think we can live with that.

Just tried out the Chrome team's demo in ChromeOS 89, and the seeking UI doesn't work right. The timecode is removed by setting duration to infinity, but the "seekable range" method does not change the seek bar at all. With and without it, seeking does not work, and the seek bar position can't be moved.

Seeking works with the video's currentTime member, but not with the UI. I've reached out to the Chrome team to see if this is just a UI bug in Chrome or a MediaSource spec bug (if it's spec'd to work this way).
