I don't know much about HDMI, but couldn't I just run the video/movie in fullscreen and then capture the output from the HDMI and save the raw output to a disk?

- userbinator 12y agoYes, HDCP has been broken for a long time and even if it wasn't, you could still capture the LVDS signal that drives the LCD panel itself. But the problem is that those are very high-speed signals(1920x1080 24bpp at 60FPS is around 350MB/s+) that require suitable hardware to capture, basically uncompressed video, and recompression would introduce more artifacts than the original. That's why pirates don't usually go this route; the result is only slightly better than pointing a good camera at the screen.
- w0utert 12y agoI always assumed most movies were ripped using exploits at various points in the playback software stack? At some point the unencrypted bitstream needs to be available to decode, if you hacked the player or GPU driver code to dump it at that point, it would be possible to re-assemble it into an unencrypted video file, right? You would use a computer without any of the DRM features the article is about of course.
