We've been throwing around some use case concepts for a while but it would be good to have a bit more of a firm list of the scenarios we want to be able to support out of the gate.
[BA] For me, the list of required simulcast/SVC use cases is pretty simple:
1. Temporal scalability. This one is basic because it is the most popular mode of H.264/SVC, and it is built in to VP8/9 and HEVC.
2. Spatial simulcast with temporal scalability. This combination of modes is supported in the Open H.264 encoder as well as quite a few commercial products.
That's it. From my perspective all other combinations of temporal/spatial/quality and simulcast are optional. That isn't to say they aren't cool, just that you can get a lot of mileage out of these two without too much complexity (or encoding horsepower).
