Record screen over MHL/HDMI
I'm working on a project in work that will require good quality video of an Android phone. I've looked at a few apps that can record your screen and output a video, but none of them give me the framerate or quality I'm looking for.
The solution I'm looking at now is using MHL to output the phone's display to HDMI, and using an HDMI capture card to record the signal. I know I can display the Galaxy Nexus' screen on a 720p television (as per the video here -> (YOUTUBE)/watch?v=ENdJv_AI5vU, sorry can't post links) but I'm concerned about HDCP. The wikipedia article for MHL states that a feature of it is:
Supports High-bandwidth Digital Content Protection (HDCP).
I'm not sure if that means all MHL signs are encrypted, or that it should be able to support HDCP on request.
Does anyone have experience with recording HDMI/MHL recording, or recording a phone's display to video in general? Any help or advice is much appreciated.
