You gave me an idea if someone was to design a small display attached to a camera paired specifically to capture high quality video not just someone propping up a camera but where external light was blocked and the image size and camera are perfectly matched with an audio input as well they may have a market.

Why not skip the display completely and just go with a capture card? They are cheap and have none of the issues with lights and timings.

I was just thinking with vendors making hardware more hostile and if they made that not a possibility where an external camera defeats that. If a capture card works then that seems even easier and if youtubedl is under attack maybe that is how people will do it but one thing is for sure, people will do it.

In theory, HDCP is supposed to prevent such use, by cryptographically verifying that the video isn't going to a device able to copy the media. Keys can be revoked by, say inserting a disc with a new set of revocations on it (alongside the media).

If you want to play such media, you have to license keys from Intel and show that your design is hostile to copying.

In theory, yes.

So yeah, it's possibile to do it, but nowadays isn't done because there are more pratical ways to record video

This is similar to how they would broadcast film on television in the early days - using a Kinescope.
