Current Streaming Setup (2016-07-20)
as of 2014-08-26
Our streaming setup is a little unique for a couple of reasons: firstly we wanted to reuse existing equipment bought for Desert Bus and other LRR projects and secondly we wanted to be able to play both PC games and every console currently available. The general setup is that all streaming goes though the Stream PC, which has 2 Blackmagic Intensity PCI cards. One card is connected to the Gaming PC via HDMI (mirroring the gaming PC monitor) and the other is connected via HDMI to a converter/switch that switches between the various consoles and converts them to HDMI as required (Wii, PS2, etc). The PS3 is connected to the switch with DVI in order to bypass HDCP. 3DS games are captured via special modded 3DS that was sent to us by a generous fan.
The audio from the Gaming PC, the Blackmagic Intensity and the microphone (a RØDE NTG2) are run into a mixing board so we can control the levels and then sent to the Steam PC via USB. USB audio takes a little bit to process, which is why the lip sync is sometimes a little bit off. We are working on a way to potentially improve this.
We use a Panasonic AF100 for the video, connected to the Stream PC via SDI to a Blackmagic Decklink Duo PCI card. This is probably way overkill for what we are usually doing but it is hardware we already had from Desert Bus.
The actual stream is run by XSplit, which we ware currently using the beta release of. XSplit's interface is a little weird, but the beta has some really great new features and seems to be stable enough for our use.

The biggest issue we have is that, when running console games, the Blackmagic Intensity can be very temperamental about switching inputs and/or resolutions. Often if we try to switch between (for example) the Xbox 360 and the Wii, the card will just display black or even BSOD the stream PC. Unfortunately, this seems to be a fundamental issue with the Blackmagic Intensity drivers, so we don't have a good solution unless Blackmagic releases a fix.
