This is the essence of minimal effort. Didn't even bother to verify all was well, two seconds of work needed, before streaming for 15 minutes. Then proceeds to tell the chat they are idiots because there was nothing he could do because he couldn't see with the headset on. That would be an excuse if the problem had occurred after he put the headset on, but it didn't. It occurred beforehand, when he had ample opportunity to glance over and see an OBS preview or his open stream video feed (which I believe is what he does.)
