Hello mates,

Sorry if a newbie question but unable to find any tip that guide me in the right direction with this issue and would be very grateful with any help.

I have a streaming camera registered with janus server and trying to access throught streamingtest.html demo I'm able to see an available stream but when pushed button to "Watch or Listen" I get the following error:

WebRTC error... Failed to execute 'setLocalDescription' on 'RTCPeerConnection': Failed to set local answer sdp: Failed to set local video description recv parameters for m-section with mid='v'.

Thanks in advance

Probably some codec related error in the SDP. Typically happens when you do H.264 and provide an unsupported fmtp, or when the codec used for the mountpoint is not supported by the browser/mobile endpoint.

Thanks!!!

This tip point me in the right direction. Camera was set at H.264, changing to H.264B or H.264H made it work!

Thanks again.
