Screen Recording Woes: Black Screen Issue with Browser Hardware Acceleration

Hey everyone,

I've been dabbling with screen recording some lectures lately and stumbled upon a curious issue that I thought I'd share here. Maybe you can shed some light on this.

So, here's the thing: Whenever I try to record a lecture with hardware acceleration enabled in Chrome, the final video is nothing but a black screen. On the other hand, when I disable hardware acceleration, everything works just fine.

I'm wondering what's causing this.

Would love to hear your thoughts or if anyone has faced something similar. Any insights or fixes would be much appreciated!

Cheers!

Hardware acceleration uses the GPU to fill some things in, that the CPU no longer knows about. The CPU just makes that spot black for the GPU to replace. Depending on where in the processing chain your capture taps off, that could be it. The Display capture is supposed to be late enough to catch what the GPU does too, if your GPU supports that, and it captures the entire screen.

BTW, Edge seems to work best here. My 12900k only sees 3% CPU utilization with a 1080p stream & around 5 or 6% for 2160p. Firefox & Chrome also produce an inferior picture to Edge.

The stream is protected & you need to keep HWA disabled.

I thought OP was *giving* the lecture, and recording that. Recording what someone else did gets into a sticky legal situation with copyright.

If it's only for your own personal archive, that's usually okay. But as soon as it goes beyond that, it's often not, unless you have specific written permission from the *actual* owner (that by itself might be hard to figure out), to do *exactly* what you're doing with it. The law in most places allows them to be incredibly granular, to prevent people from asking for an inch that would be okay as far as they asked, and then taking a mile that is definitely not okay!

You thought wrong & save the legal speak. There's nothing wrong with recording, it's what's done with it after the fact. That's on the OP.

Was using Google Chrome till now but will give Edge a try. Thanks for suggesting.

Thanks for pointing out the legal aspects of this situation. I only use OBS for educational purposes (no pun intended).
