Audio Mixer

[Farzan Shojaee]

Hi all,

 

I want to use Gstreamer to receive audio streams from multiple points on the same port.

Indeed I want to stream audio from different nodes on the network to one device that listen to incoming audio streams, and it should mix multiple audios before playback.

I know that I should use 'audiomixer' or 'liveadder' to do such a task.

But I can't do it, and the mixer doesn't act correctly and when two audio streams came, the output sound would be so noisy and corrupted.

 

I used the following command :

 

gst-launch-1.0.exe -v udpsrc port=5001 caps="application/x-rtp" ! queue ! rtppcmudepay ! mulawdec ! audiomixer name=mix mix. ! audioconvert ! audioresample ! autoaudiosink

 

has anybody any solution to do this job???

Every guidance would be appreciated.

 

Thanks all,

Farzan Shojaee

you can't do that.   assign each port to each audio stream, receive each stream,

then mix them with adder.

Otherwise, your receiving data is interleaved at udp packet level.
