I think Adobe Media Encoder (AME) is being confused with Flash Media Live Encoder (FMLE) here. FMLE is what needs to be “hooked into” in order to live stream from a video source.
The decision on whether or not to use a TriCaster is a matter of need. If you need a turnkey solution and don’t have a lot of in-house tech support, the TriCaster is your thing. Also, if you need to ingest multiple analog sources, the TriCaster is your thing.
If, however, you are starting from scratch in a fully digital environment and do not need to interact with analog sources, then BMD should be given serious consideration.
I would suggest you make a list of what you need and contemplate needing, them compare it to the feature set of the TriCaster and the BMD devices. Whichever one meets most of your needs wins.
