Help No Audio in Multicast Steam
Completed
We have an enterprise IPTV system with cameras that stream native multicast. The multicast streams have embedded audio, which can be decoded loud and clear with VLC and within our Haivision IPTV system. We are also ingesting these streams into NXwitness for recording and control. Adding the "device" through the udp://@239.x.x.x url works perfectly fine for video, however even with the audio switch enabled there is no audio in the live view or the recorded video. I've tried switching the camera source from AAC to .711 but there is no difference. Unfortunately the cameras I'm using don't support simultaneous RTSP and UDP streaming.
Any help on this would be appreciated!

Hello,
It looks like a bug.
Could you please indicate OS version, VMS build, camera model and firmware version?
Please, do the following
- delete the camera from the Server
- change log level of the Server to DEBUG
- start traffic capturing the traffic with wireshark
- add the camera to the Server through multicast 239
- enabling audio in the camera
- open the camera on the scene
- stop the Server
- stop traffic capturing
Share with us traffic capture file and archived log directory of the Server.
