The room we use at Google has a nice mixing desk and SDI converter, so
we just use a Blackmagic SDI capture card to get the video stream from
that. DVSwitch would definitely be the solution I would go with if I
didn't have that.

I'm hoping to figure out a system to trunk back via a Telsta NextG card.
This would make the system truly portable and usable by groups which
don't have access to internet at their venue.
 


    I'd like to encode to webm or similar - something that can take
    advantage of multiple cores. As it stands, Theora is only encoding
    on one core, and it takes a lot of CPu to encode well.


Once you have a good stream, you can send it to a beefy server on the
internet which then transcodes to the multiple HTML5 (and flash for fall
back) formats. I'm using flumotion for this part you can find my code
at https://github.com/timsvideo

I then use an AppEngine app to serve a HTML page which embeds the video,
an IRC widget and a twitter stream. This allows people who only have a
web browser to participate. This system also has a "in room view" which
we project onto our second screen so the speaker and audience can see
what is going on online.
