First, thank you for this framework. It looks like just what we need to stream live video from our BlackMagic Intensity Pro to a wowza flash server. The problem is that we would like to stream in a few different qualities, and we would also save a version to the harddrive. Using avformat I have managed to use both melt and python-mlt to do one stream or to save to harddrive, but not multiple streams and file at the same time. So is this possible? I see that you are in the process of adding multiple consumers to mlt, is this stable enough, is it another way to do this, or is it not possible?
