The video feed didn't stop working, or if it did, it was only for a brief moment.
If you watch this part of the YouTube stream, after it cuts back to the two hosts there is a monitor at the far right center of the video that shows the continuing camera feed of the drone ship landing pad. Only part of the monitor is visible, but after the smoke clears over the next few minutes you can see the empty pad:
You can also see the surprised reactions of the hosts during these few minutes, and how relieved they were when John Insprucker joined them to wrap things up. It would have been interesting to be a fly buzzing around their earpieces to hear what the producers were telling them!
People have speculated that with everything else in the mission being so spectacularly successful, they wanted the initial news reports to be about that success instead of the one core that failed to land.
Knowing how the news works - "Here's what's wrong with the world today!" - I can sympathize with that.
Although I understand why they would have done that for click-bait news outlets, it did really bother me that they were so slow in revealing what happened. What I like about SpaceX is that they're always been very open about their failures, even compiling that great video of their failures. Being able to seeing the full result would have been nice, and I spent a fair bit of time for the following hours refreshing Twitter.
They weren't only slow about revealing it, they straight-up lied.
Smoke on deck clears, no core visible, deck empty. Both go "oh." and after a pause, while looking at the empty deck: "we're waiting to hear what happens. [...] we'll let you know as soon as we find out" and "we'll [...] know [...] whether it's standing". All while looking at the empty pad.
They saw it didn't land, they found out immediately and didn't let "us" know. Instead they claimed it might be possible it is standing despite seeing the empty deck.
The aftermath of this was the most confusing thing ever. In the screen in the background that they forgot about, right when the smoke clears the crowd started cheering. We also could only see the left half of the barge. It certainly left everyone wondering until the official confirmation.
