multipoint rtp streams?
Locked
 
|
Hi All,
I would like to know if it is possible to stream 1 source to multiple destinations with the rtp pipeline by adding more udpsinks. For example I tried: REMOTE_HOST1=127.0.0.1 REMOTE_HOST2=192.168.0.1 gst-launch -v gstrtpbin name=rtpbin \ jackaudiosrc connect=none ! audio/x-raw-float, channels=8 ! \ vorbisenc quality=0.3 ! rtpvorbispay ! \ \ rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink port=5000 host=$REMOTE_HOST1 ts-offset=0 \ rtpbin.send_rtcp_src_0 ! udpsink port=5001 host=$REMOTE_HOST1 sync=false async=false \ udpsrc port=5002 ! rtpbin.recv_rtcp_sink_0 \ \ rtpbin.send_rtp_sink_1 rtpbin.send_rtp_src_1 ! udpsink port=5003 host=$REMOTE_HOST2 ts-offset=0 \ rtpbin.send_rtcp_src_1 ! udpsink port=5004 host=$REMOTE_HOST2 sync=false async=false \ udpsrc port=5005 ! rtpbin.recv_rtcp_sink_1 But this gives me the following after some time: ERROR: from element /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: Internal data flow error. Additional debug info: gstbasesrc.c(2378): gst_base_src_loop (): /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: streaming task paused, reason not-linked (-1) Then I added a queue so both udpsinks could read from that, but I cant seem to get the syntax right. Hints or pointers are very much appreciated. Thanks in advance! Best, Dirk ------------------------------------------------------------------------------ Come build with us!

Hi Wim,
Thanks for the reply! Sadly, Google did not point me to an example of how to use this, but I presume by looking at the documentation I have to use the 'add' signal? Which I think means I cannot do it from the commandline, but need Python or C. Could you maybe give me hint on it's use?

gst-rtsp-server uses it when the media can be shared between clients.
Like here: http://cgit.freedesktop.org/gstreamer/gst-rtsp-server/tree/gst/rtsp-server/rtsp-media.c#n1487 Wim On Mon, Oct 19, 2009 at 8:32 AM, Dirk Griffioen <[hidden email]> wrote: > Hi Wim, > > Thanks for the reply! > > I would like to know if it is possible to stream 1 source to multiple > destinations with the rtp pipeline by adding more udpsinks. > > > Check out multiudpsink. > > > > Sadly, Google did not point me to an example of how to use this, but I > presume by looking at the documentation I have to use the 'add' signal? > > Which I think means I cannot do it from the commandline, but need Python or > C. > > Could you maybe give me hint on it's use? > > Best regards, Dirk > > > ------------------------------------------------------------------------------ > Come build with us!

Hi Wim,
Thanks for the reply! I had a look at it and it was quite helpful ... I came up with the following python example that seems to do the streaming. I'll post it below, maybe someone finds it usefull. Best regards, Dirk ////// import gst host1 = "127.0.0.1" port1 = 1234 host2 = "192.168.0.1" port2 = 4321 audiotestsrc = gst.element_factory_make("audiotestsrc") audioconvert = gst.element_factory_make("audioconvert") rtprawpay = gst.element_factory_make("rtpL16pay") multiudpsink = gst.element_factory_make("multiudpsink") pipeline = gst.Pipeline('server') pipeline.add(audiotestsrc, audioconvert, rtprawpay, multiudpsink) gst.element_link_many(audiotestsrc, audioconvert, rtprawpay, multiudpsink) def client_added(sink, host, port): print host, ":", port multiudpsink.connect("client_added", client_added) multiudpsink.emit("add", host1, port1) multiudpsink.emit("add", host2, port2) def print_stats(): def _print(data, host, port): stats = "%s:%s bytes_sent: %s, packets_sent: %s, connect_time: %s" %(host, port, data[0], data[1], data[2]) print stats data = multiudpsink.emit("get_stats", host1, port1) _print(data, host1, port1) data = multiudpsink.emit("get_stats", host2, port2) _print(data, host2, port2) return True import glib glib.timeout_add_seconds(1, print_stats) pipeline.set_state(gst.STATE_PLAYING) import gtk gtk.main() gst-rtsp-server uses it when the media can be shared between clients.
