If so, I don't think that's actually what he said. In any case, speaking as someone who actually has to deal with this, it's more work to maintain more code paths. Thus, I anticipate using Cisco's binary on all desktop platforms and only using platform codecs where it offers a significant performance advantage, e.g., on mobile. On a related note: it's a mistake to assume that just because there aren't currently good interfaces to the existing H.264 encoding hardware that those interfaces will never exist. For instance, the iPhone clearly has real-time capable encoding hardware, and Apple certainly could make it available if they wanted. That's a much simpler proposition than adding hardware where none exists. -Ekr
