<div>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.</div>
<div><br>
</div>
<div>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.</div>

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.<br>

<div>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 <a moz-do-not-send="true"

<div><br>
</div>
<div>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.</div>
