Gstreamer Mac OS X udpsink error

Question

I’m trying to stream audio in Mac OS X but I keep getting this error:

gst-launch osxaudiosrc ! audioresample ! audioconvert ! alawenc ! rtppcmapay ! udpsink port         


        

Answer 1

There is a bug in the udpsink/multiudpsink code related to IPV6 enabled systems and socket creation.

If you are coding up your pipeline in C you can bypass this by manually creating the socket to use and using that for the sink like so.

my_sink = gst_element_make_from_uri(GST_URI_SINK, "udp://233.34.28.1:31337", NULL);
int my_tx_socket;
my_tx_socket = socket(PF_INET, SOCK_DGRAM, IPPROTO_UDP)
g_object_set(G_OBJECT(my_sink), “sockfd”, my_tx_socket, NULL);

If you were just going to use it using gst-launch I'm afraid that you will have to edit your way through multiudpsink.c until you figure out how to bypass thus.
