I use uStream.TV to stream my broadcasts. I also have a BlackMagic Intensity Pro that I use to capture my video sources. Using Flash Media Live Encoder, I can stream my video from the Intensity Pro to uStream if the video coming from my source is NTSC. I don't stream the NTSC source, I end up downscaling my videos down to 640x320. However, I noticed that if I set my source to 720p, then FMLE won't pick it up anymore. Is there a reason why I can't use an HD source with FMLE? I understand not being able to broadcast an HD source, but I should at least be able to read it in.
The reason I want to do this is so that I can record the source in 1280x720 HD (using Cineform Prospect), while at the same time live streaming the source in 640x320. Why is this not possible? I have a computer powerful enough to do it...
