Tip: Faking an HDMI Connection

FITPC-HeadlessLast 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.

Interconnecting Jitsi Video Bridge, ZipDX & YouTube Live

In the production of over 530 VUC sessions we’ve undertaken some odd and occasionally rather complicated arrangements. Quite possibly the most complex is when we interconnect the WebRTC-based Jitsi Video Bridge with YouTube Live and the ZipDX conference bridge. I set about described aspects of this process a year ago, but stopped short of describing how the entire arrangement worked. Well, worked most of the time. This article will bring you current with my various attempts to make this process robust and repeatable.

Preface: When we use Jitsi Video Bridge we lose a couple of the conveniences that come with a Hangout-On-Air. Where a Hangout-On-Air has an automatic link to a YouTube Live event, we must do this manually when we use JVB.

BlackMagic, Nexus Devices, MHL and SlimPort

As I tinker with various things around here I’m finding that I need some tools to be able to capture experimental results in a manner that provides assets for this blog. Recently I’ve added a couple of new tools which I though you might find interesting.

This process of “tooling-up” started last year when I purchased a BlackMagic Design Intensity Pro capture card. That card has been mentioned a few times previously. It allows me to capture video from an HDMI connected source.

The Intensity Pro card has been very handy for a variety of things. Since computers these days are capable of screen resolutions that are also common to HDTVs I have used it to record the output of PC desktops. That has included screencast tutorials as well as the output of specific programs, like Adobe Audition.
