I just tried the suggested RTMP ingest to WebRTC and subscribing fails.
I get this error on the play sample. Exactly like I am experiencing with IOS publishing right now.
"‘setRemoteDescription’ on ‘RTCPeerConnection’: Failed to set remote offer sdp*: Failed to set remote video description send parameters* "
Here is the full offer and error. There is no candidate and the high h264 profile level which is breaking. The same result with IOS publishing I think.

It’s the same error with webrtc publisher if the H264 level isnt filtered to “42e01f”, It does not like 64C028. Wowza refuses to send candidates.

We just published a new article on this today and maybe this will help:
If not, send us a support ticket and we’ll take a closer look. Tech support doesn’t debug in the forums.
I found this. I have that constraint configured. Still wont subscribe
