A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

They could use stream encryption (DRM) to ensure you're viewing the ads as expected and make it hard to capture and playback.

Its a arms race, you could always just record the screen with a camera and edit it out as the ultimate.

you could spin up a vm, and capture the video output

you could use a graphics driver that lets you inspect the frame buffer, etc

you could use the side channel attacks to get the decrypted video frames, heartbleed etc, etc etc

Do these actually work against HDCP? (Outside using a camera, obviously). I know it used to work decently well against most "ordinary" attacks like VMs and capture cards.

I believe HDCP keys have already been leaked, I can find a couple different references to them on GitHub even.
