I want to stream recorded video while allowing people to chat. What do you think about Adobe Dreamrever?
I think Adobe Dreamweaver is a nice program for editing code. Wait what?! There is nothing in Dreamweaver that will allow you to do this, I'm very sorry. What you're looking for will likely be a flash-based solution, and likely having coding done in Flex, not Dreamweaver. This won't be easy or cheap, so I'd really suggest looking into already-made solutions you can tailor to your own. Check out uStream, YahooLive, and stuff like that and see if anybody out there that offers live online video chat also has a way you can host it or embed your own chat room into your website. Trying to do this on your own will most likely fail, and be terribly expensive as it's failing.
innovati is right, Dreamweaver will allow you to make the site but will do zip for the video. You can do it all yourself depending on the volume of traffic, just put a flash player on your page, put the video on your web hosting and put the right embed code in and that's it, however it really doesn't scale very well, can fall part with as little as 5-10 concurrent users. Depending on your budget you can use something like uStream as innovati has already suggested, or if you do want to do it yourself (IE you may want better quality or more control) find a CDN that has adobe flash video serving capabilities, host the video file on there, although that does the same job as video hosting sites do so you may as well use them. Doing it the CDN way will be more expensive than a pre-rolled solution but will allow you more flexibility, however uStream will be easier although I'm not sure it does recorded content only live. Are you looking to display the same video to everyone at the same time (IE like a live feed) or is going to be on demand IE anyone in the chat room can watch the video when they want? If its going to be on demand there are loads of video hosting companies, such as YouTube (Bottom end), Vimeo and loads of others that will give you high quality streaming at low(ish) cost. Jen
Youtube now accepts 'HD' videos at H264 with 720p resolution, which isn't bad at all, and it's better than Vimeo Standard, but nowhere near Vimeo HD.
if you want to make something custom I would recommend you to take a look at longtailvideo. It makes streaming of various filetypes possible.
