Recently I encountered a problem with trying to do a video capture of a game I was playing on an Android device. The device in question happens to be a RCA tablet, and I was using an Elgato Game Capture HD device.
On the Elgato game capture program I noticed that although the signal was being detected, it wasn’t showing the screen. It stated something about disabling HDCP in order for it to work. Upon doing some Internet research, I discovered that HDCP–which stands for high-bandwidth digital content protection–was a content protection scheme implemented on connection like the one I was working on.
I thought that I just wasted about $7 buying this HDMI A type (standard size) to C type (mini size) cable (a BlueRigger high speed mini HDMI to HDMI cable, 6 ft — http://amzn.to/1dDQ4Y8) because the connection is blocked by this HDCP protection scheme.
Upon doing a bit of checking around on the web, I found that purchasing a certain HDMI splitter can get around the issue. I found the ViewHD 2 Port 1×2 Powered HDMI Mini Splitter (http://amzn.to/1KDlloV) for about $24. I received and tried it, and low and behold, I can do video screen capture! Problem solved.
