setRemoteDescription - Failed to parse audio codecs correctly.

[Ramasundar Kandasamy]

Hi,

On setting the remote sdp with the sdp given below, i am getting " Failed to parse SessionDescription. a=ssrc:2929509848 mslabel:0i6fakBZbBElbYAf3sUvVaCDqeX07Od2O3j6 Failed to parse audio codecs correctly."

Did anyone have experience with similar errors?

Thanks
Ram

You're probably trying a hack the SDP and making it invalid.
A codec with payload type equal to 111 is removed from the audio line
but you forgot to remove all the fmtps:
> a=fmtp:111 minptime=10
Remove this line

Hi 

 I'm getting similar error on parsing audio codec. The set up is Our client on Chrome(M35) <--> Our server with SIP statck <--> Doubango <--> SipML5(Chrome M35). I've attached the SDP offer from our client and the SDP answer we got from SipML5. When we try to parse the answer, we get "Error setting SDP"Failed to parse SessionDescription. Failed to parse audio codecs correctly." . Can you please let me know which part of SDP answer from SIPML5 is causing the error? 

    The config file on doubango - enable-media-coder is no, in Expert mode.htm, RTCWebBreaker is not enabled since both endpoints are WebRTC aware. 

Thanks
