So, diving into this realm at work. Not something I'm familiar with.
Anyone have any favorites on being able to broadcast live video right out to the web and record it also?
V-brick hardware has always been super reliable, but it is very expensive. If you need to reach lots of people, it is worth looking into using a Content Distribution provider. (Akamai, Limelight, etc.) This way, you don't have to buy and maintain the media-servers that are used for the final distribution of the content to users.
On the production side, Telestream Wirecast is hard to beat for providing a slick, high-end look for not a whole lot of money! It will record to disk, and it has limited direct-streaming capabilities.
The software is designed to push to a streaming server or 3rd party distribution network, so the internal streaming server is not really designed to serve a large audience. A little bit of a learning curve, as it uses lots of "broadcast" terminology, but it is pretty amazing what you can do with it. There is also a "desktop capture" plugin that can be used to capture a presenter's laptop via the network. http://www.telestream.net/wirecast/overview.htmhttp://www.telestream.net/company/press-kit/download/Wirecast_workflow.jpg
Worth a look. I believe there is a free trial that has full functionality, but watermarks the video.
