• High end PC (HP) for Second Life virtual camera. Whatever Zoraster Gaffer sees is my camera.
  • MacBookPro gets video signal and sends it out to streaming server with Wirecast; second SL client view is for me to "be there"
  • Out of view is the Canopus ADVC110 for converting analog video and audio from PC to DV
  • This has nothing to do with streaming; just my recyclables!

Second Life Live Video Stream Setup

Newer Older

My home office technology used for the NMC Symposium on Evolution of Communcation held entirely in Second Life.

The PC on the left, a high-end HP m8100y Core 2 Quad 2.40 GHz , 4 Gb RAM with nVidea GeForce 8500 GT (512Mb), is my Second Life camera, operated by my alt avatar, Zoraster Gaffer. Mirrored video output from its video card is sent by S-video and audio out form my speakers to a Canopus ADVC110 digital/analog converter, which in turn passes the signal by firewire to my MacBook Pro.

On the MBP, I run Wirecast which sends the video to our QuickTime streaming server. This video can thus be viewed by people outside of Second Life, as a normal live video stream, but the real use was to attach the video to our overflow sims in Second Life. The main NMC Conference center can accommodate up to 70 avatars; once that limit is reached we send people to 2 other sims where the live video is available. see the desktop screenshot

To participate in the activities, I am also logged onto Second Life on the MacBookPro as CDB Barkley. This is always risky as an SL crash would take down the entire video stream. For some strange reason this never happens.

Bandwidth held up okay - I get about 2.5 Mbps down and > 1 Mbps up on my DS modem; both machines are connected by wire. The outgoing video stream takes about 300 kbps upstream, and the two Sl clients take about 1 Mbps down.

Looks like I need anther computer!

The white box is not part of the set up- just my recyclable can!

    Alan! This setup is awesome! I've heard so many people complain about the limits of SL for big events, but I attended in one of the overflow locations and it was VERY cool! The audio was great, and I didn't feel like I was getting less of an experience at all. Thanks for sharing the tech behind the genius.

    Does exist and object able to be an inworld camera and sending directly live video stream to a web server ?

    Best regards from France.

    Thanks for helping confirm what I always thought...
    Macs are better for streaming
