Any way to defeat HDCP for Chromecast recording? (startrek.website)

I have my Linux box running my TV and it works great, but I'd like the ability to treat my Chromecast as a desktop window for streaming without switching inputs, multitasking etc. I have an HDMI capture card that works great with a Switch, but the Chromecast detects it's not HDCP (DRM) compliant so it won't work. Is there a way to outsmart that detection with software or hardware?

I've heard some knock off hardware confuses it enough to work but it seems like the info is old and I'd rather not roll the dice on hardware that's otherwise garbage...

DRM tends to mess with your game, framerate even. People who pirate don't have that problem.

Not necessarily. Often times DRM doesn't get removed or completely bypassed, instead they only make the license check pass. In this case performance should be identical to the licensed original.

So a license check which cost several cpu cycles, and maybe even a call to a server is replaced with a noop. And you say identical performance?

Yes. Some cracks don't replace the call to a server entirely, and instead use a local server to return the expected response. In this case, the DRM would run normally, except for it not contacting the offcial remote server.

Obviously if a crack removes a DRM completely, there might be a performance advantage. It depends on several factors.
