Hey, all Well, I have this pipeline: gst-launch -v filesrc location=notice.html ! identity ! udpsink host=127.0.0.1 port=6000 udpsrc port=6000 ! identity ! filesink location=notice2.html there is 2 streams and works fine. The file notice2.html is recorded. But, when I change the pipeline to pulsesrc: gst-launch -v pulsesrc ! identity ! udpsink host=127.0.0.1 port=6000 udpsrc port=6000 ! identity ! filesink location=soundRcvd.wav does not work. However, when I run the sender stream on one terminal: gst-launch -v pulsesrc ! identity ! udpsink host=127.0.0.1 port=6000 and the receiver stream on another terminal: gst-launch -v udpsrc port=6000 ! identity ! filesink location=soundRcvd.wav, that works! The voice is recorded on the destination file. I have no idea what is going on here. Any tips? Thanks a lot. Marcelo de Sá Mendoza
