[gst-devel] gstrtpbin and langage C

[Guillaume Dorchies]

Hello

I try to create a little rtp server with gstreamer in C or in ruby.

Where can I find a translation of this line "gst-launch-0.10 -v gstrtpbin
name=rtpbin \
       filesrc location="/data/file.mp3" ! mad ! audioconvert !  rtpL16pay !
rtpbin.send_rtp_sink_0  rtpbin.send_rtp_src_0 ! udpsink port=5000  "

in C or in ruby.

I wrote this code in ruby

def create_pipeline_hard
  # Create a pipeline to hold the elements
  pipeline = Gst::Pipeline.new("my_pipeline")

  filesrc=Gst::ElementFactory.make("filesrc","filesrc")
  filesrc.location=FILE_ONE


  mad=Gst::ElementFactory.make("mad")
  audioconvert=Gst::ElementFactory.make("audioconvert")
  pay=Gst::ElementFactory.make("rtpL16pay")

  @rtpbin=Gst::ElementFactory.make('gstrtpbin','rtpbin')
puts @rtpbin.public_methods.inspect

  udpsink=Gst::ElementFactory.make('udpsink')
  pipeline.add( filesrc, mad, audioconvert, pay, @rtpbin, udpsink)

  @rtpbin.signal_connect("pad-added") do | source, pad |
puts "in pad-added #{pad.name}"
    if pad.name.include?('send_rtp_src')
      pad.link(udpsink.get_pad('sink'))
    end
  end

  filesrc >> mad >> audioconvert >> pay #Link the pads

#  send_rtp_sink=@rtpbin.get_request_pad('send_rtp_sink_%d')
  send_rtp_sink=@rtpbin.get_request_pad('send_rtp_sink_0')
  pay.get_pad('src').link(send_rtp_sink)

  return pipeline
end

the pipeline work but it don't send music


Thanks a lot
Guillaume
