I don't think this is the case. The rationale is that H.264 can be accelerated by hardware. Some rightly question how much this is actually the case natively today. To Ekr's point, if Cisco works with the top providers to enable true acceleration.... Or in the case of Apple, if ultimate delivery of true h/w acceleration of 264 is ultimately delivered through WebRTC... Then at least we' have *more* h/w acceleration than we do today Sent from my iPhone On Nov 2, 2013, at 6:28 PM, "Emil Ivov" <emcho@jitsi.org<mailto:emcho@jitsi.org>> wrote: I'd encourage you to read back.

Those platforms > can all support H.264 to the extent that Skype requires. Martin, can I ask you to talk with your Skype engineering team and check up on the exact way that works on iOS. Last time I looked, it seemed you couldn’t use the Apple supplied (hardware accelerated) h264 library for realtime encode/decode and it wasn’t at all clear to me that the hardware encoder licence covered any soft implementation of h264 we added. I’d like to caveat that: 1) it was a while ago. 2) I’m not a lawyer. 3) it was a thought experiment. So it would be interesting to get a current view from the trenches.
