Problem with the command duplicate

[Lucius9]

Hi everybody !

I would like to know if it is normal that when I duplicate a stream, I just have the video stream on the display and no sound at all.
I have sound in the transcoded stream but not in the original. Here is the model of my command :

#duplicate{dst=display,dst=transcode{.....}:rtp{sdp=rtsp://:8554/streamName.sdp,mp4a-latm}}
