Headless

Last week I once again saw a need to share the output of an Android device. As I’ve described previously, this requires the use of an HDMI splitter to feed both a monitor and the HDMI capture card in my vMix PC. The monitor satisfies that HDCP handshake, which allows the PC to see the video stream.

However, there are times when it’s just not convenient or practical to have an extra monitor involved. This came up recently in a thread in the Wirecast support forum. Someone wants to capture the screen of a number of Mac Mini’s in order to bring multiple Skype video calls into a streaming production. They run the Mac Mini’s headless, accessing the Mac desktops using a software screen sharing application.
