My desired feature would be:
The ability to record the local file in HD, but only broadcast a Medium Quality stream for the live audience.
At the moment, the only way I can see to do this is to choose one of the preset multistreaming options like HD+Medium+Mobile. But that is too much for my bandwidth to handle - I don't want to be sending the HD and mobile streams to the live channel, I only want people to see the Medium version and still have the HD version recorded to my PC.
My upload speed is only 600kbps. If I try to send an HD stream it either buffers constantly for the viewers or drops after a few seconds. But I can send a medium quality stream just fine. I don't really want to use a third party program to do the local HD capture.
