I have the other problem. When I creating offer by using
"{'mandatory': {'OfferToReceiveAudio': true, 'OfferToReceiveVideo':
true}}", FF 33 will tell me "Mandatory/optional in createOffer
options is deprecated! Use
{"offerToReceiveAudio":true,"offerToReceiveVideo":true} instead
(note the case difference)!". However, the offer is still created
successfully and function onCreateOfferSuccess is called. But if I
use "{'mandatory': {'offerToReceiveAudio': true,
'offerToReceiveVideo': true}}" to create the offer again, FF 33 will
call function onCreateSessionDescriptionError. The error is "Cannot
create SDP without any streams.".
That sounds like a bug to me, which probably got introduce when the
new constraints got implemented. If you haven't done it already I
would appreciate if you could file a bug report on Bugzilla about that.
No, this isn't a bug. What happened is that the spec for
PeerConnection no longer includes "mandatory" at al.
The string that Aslan used was "{'mandatory': {'offerToReceiveAudio':
true, 'offerToReceiveVideo': true}}"
You'll see that it still contains the word "mandatory." He didn't fix
the problem that the warning was telling him about
("Mandatory/optional in createOffer options is deprecated").
What the error is trying to say is:
Old syntax: {'mandatory': {'OfferToReceiveAudio': true,
'OfferToReceiveVideo': true}
New syntax: {'offerToReceiveAudio': true, 'offerToReceiveVideo': true}
So basically the old 'mandatory' ignores the new parameters
'OfferToReceiveAudio' and 'OfferToReceiveVideo'. Therefore the
'mandatory' part is empty. Which results in a PeerConnection with
sendrecv, which then complains about the missing media input.
Nice mix-up of old and new config parameters.
