+1 for async, and async always. On 9 May 2012 09:44, Eric Rescorla <ekr@rtfm.com> wrote: > Do I have to call setLocalDescription() from the callback?

This should be just a blob of data, and who knows what you might need to do to "tweak" the offer. Maybe you have that logic on a server somewhere. The only concern is if the conditions have changed in such a way that the offer is available for a strictly limited time. I suspect however that this is always the case and setLocalDescription can fail, even with an immediate call with unmodified offer. If it takes 100ms to get the info, some of the info could be up to that old when it arrives, giving a 100ms window for stuff to happen (other tabs to grab the camera, user to revoke permissions, etc...). createOffer doesn't create any commitment after all. --MartinReceived on Wednesday, 9 May 2012 17:23:46 UTC
