[jitsi-dev] No audio in mixer mode


#1

Hello everyone,

I've been trying to get videobridge to do audio mixing using Rest Apis.

when using rtp-level-relay-type=mixer with dynamic payload types - no
audio packets are sent out from videobridge and following error is
logged

SEVERE: [7125] net.sf.fmj.media.Log.error() No format has been
registered for RTP payload type 111

I'm sending payload types in Rest Api patch request to the Videobridge
after allocating the channels and no error reported in videobridge logs.

I also tried the audio mixer mode with static payload types (G711) and
this time I got the audio stream from Videobridge but with payload type
G722 while the endpoints were sending audio with payload type G711
But G722 is not negotiated on chrome so could not get it working this
way.

Has anyone tried audio mixing with the Rest Apis ? I'd appreciate any
pointers on how to resolve this.

Thanks,
Divya

Hi,
I tried the audio mixer mode with static payload types (G711) and this
time I got the mixed audio stream from Videobridge but with payload type
G722 while the endpoints were sending audio with payload type G711.

I am sending payload types to the Videobridge after allocating channels
(in Patch Rest Api) but the videobridge does not seem to using the
payload-type info.
I tested this on build 342.

BR,
Divya

Did you send the payload types to the Videobridge when/after allocating
the channels?
[DS] Yes
{"id":"111","name":"opus","clockrate":"48000","channels":"2"}

Is either one of 111 and 116 the payload type number with which the
endpoint is sending audio to the Videobridge?
[DS] 111 is the payload type number with which Endpoints are sending
audio to videobridge
