I'm getting the following error with tp-farsight
=========================================================================
Traceback (most recent call last):
File "/home/lateef/teletest/MediaChannelStreamer.py", line 54, in
__stream_created_cb
src.get_pad("src").link(srcpad)
gst.LinkError: <enum GST_PAD_LINK_WRONG_HIERARCHY of type GstPadLinkReturn>
=========================================================================
The code in question:
========================================================================
def __stream_created_cb(self, channel, stream):
print "Start of stream created!"
stream.connect("src-pad-added", self.__src_pad_added_cb)
srcpad = stream.get_property ("sink-pad")
from gst import element_factory_make, STATE_PLAYING
src = element_factory_make("audiotestsrc")
src.get_pad("src").link(srcpad)
src.set_property("is-live", True)
src.set_state(STATE_PLAYING)
self.__pipeline.add(src)
print "End of stream created!"
return False
def __src_pad_added_cb(self, stream, pad, codec):
print "Start of __src_pad_added_cb"
from gst import STATE_PLAYING, parse_bin_from_description
sink = parse_bin_from_description("audioconvert ! audioresample

pad.link(sink.get_pad("sink"))
sink.set_state(STATE_PLAYING)
self.__pipeline.add(sink)
print "End of __src_pad_added_cb"
return False
def __session_created_cb(self, channel, conference, participant):
print "Start of __session_created_cb"
self.__pipeline.add(conference)
from gst import STATE_PLAYING
self.__pipeline.set_state(STATE_PLAYING)
print "End of __session_created_cb"
return False
====================================================================================
I'm not a Gstreamer expert so I appreciate any help.
