Here's a horrible channel that leaves 'live' up all the time, yet no timecode, no stopping the vid to restart in live. But he has his live with the red light on. I don't think it's my browser.
This is one big hyperlinking personal advertising site. It's click bait. I'm finding a lot of this shit lately. It's either google, or the channel owner allowed to do that. He's disabled the timeline interaction and all he's doing is downloading actual nasa videos and replaying. I'm not sure if he needs permission to do this.
As compared to the true nasa channel where you can pause the vid, then click on live again. Click on the red line, move toward the live word then above the word live, the note- 'skip ahead to live live broadcast' appears and when clicking 'live' the red light comes on. But most also have time showing.
Here's another that is truly live with timecode rolling. I've bookmarked it too. It's neat to time trip as well. If the timecode is not rolling, just refresh it. Sometimes they change shots and it doesn't change over right.
