Two Audio Streams In One Pipeline

Two Audio Streams In One Pipeline
 
|
Hi
Is possible to have two streams( 1 sender 1 receiver ) or more, of audio in one pipeline only? I'm trying to do that and I getting frustrated. I made two pipelines for each stream and worked cool, I hear the audio received from the host and the host hear what I talk. The thing is that I need to do that in ONE pipeline, but I can't. I know that two streams are possible in one pipeline, cause when I do the test below, it works: gst-launch -v filesrc location=notice.html ! identity ! udpsink host=127.0.0.1 port=6000 udpsrc port=6000 ! identity ! filesink location=notice2.html but when I change to pulsesrc/pulsesink that doesnt work. Works only in diferent pipelines. There's something else that I need to do? Thanks for the atention. ------------------------------------------------------------------------------ Come build with us!

You probably want to use rtp for sending audio over the network. Also if something does not work, tell us what errors you get. Otherwise we can't help.

Hi Stefan,
Sorry to diverge slightly from the topic, but, I do have a query on two streams. I tried doing this using gstreamer: - Create two different pipelines for two streams. (Create different elements for each pipeline but these elements refer to same hardware units). - Play stream1 while stream2 is in PAUSED state. - After few seconds, PAUSE stream1 and move stream2 to PLAY state. - I notice that stream1 plays and pauses but stream2 does not play actually. Will the above scenario work and if yes, do you see anything that needs done apart from the above ? thanks and regards, Rajesh Marathe.

Hi, Stefan!
Thanks for you reply. So here is the pipe with two streams that dont work together: gst-launch -v udpsrc port=5000 caps="application/x-rtp,media=audio,payload=3,clock-rate=8000,channels=1,encoding-name=GSM" ! .recv_rtp_sink_0 gstrtpbin ! rtpgsmdepay ! gsmdec ! audioconvert ! pulsesink gstrtpbin name=rtpbin autoaudiosrc ! gsmenc ! rtpgsmpay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! identity ! udpsink port=5000 host=127.0.0.1 I do not get any error when running that pipe! But I cant hear anything when running it. However, when I separate the streams, like below, and run then on different terminals, that works(but that is like two pipes and I dont want two pipes). The audio is captured and sent and I hear myself as I talk. receiver stream: gst-launch -v udpsrc port=5000 caps="application/x-rtp,media=audio,payload=3,clock-rate=8000,channels=1,encoding-name=GSM" ! .recv_rtp_sink_0 gstrtpbin ! rtpgsmdepay ! gsmdec ! audioconvert ! pulsesink sender stream: gst-launch -v gstrtpbin name=rtpbin autoaudiosrc ! gsmenc ! rtpgsmpay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! identity ! udpsink port=5000 host=127.0.0.1 As I said before, I do not get any error when running those streams in one pipeline, but I cant hear any audio sent through udp... 2009/10/30 Rajesh Marathe <[hidden email]> Hi Stefan, ------------------------------------------------------------------------------ Come build with us!
