I'm attempting to create a regular filter type element with gst-python.  Here
is my fist attempt at writing a plain passthru filter.

I was not quite sure how the GstElementDetails part translated into the python
binding.

Am I on the right track?

class TestFilter(gst.Element):

  _srcpadtemplate = gst.PadTemplate ("srcpadtemplate",
                                     gst.PAD_SRC,
                                     gst.PAD_ALWAYS,
                                     gst.caps_new_any())

  _sinkpadtemplate = gst.PadTemplate ("sinkpadtemplate",
                                      gst.PAD_SINK,
                                      gst.PAD_ALWAYS,
                                      gst.caps_new_any())

  def __init__(self):
    gst.Element.__init__(self)
    self.srcpad = gst.Pad(self._srcpadtemplate, "src")
    self.inkpad = gst.Pad(self._sinkpadtemplate, "sink")
    self.add_pad(self.srcpad)
    self.add_pad(self.sinkpad)

    self.sinkpad.set_chain_function(self.chainfunc)
    self.sinkpad.set_event_function(self.eventfunc)

    def chainfunc(self, pad, buffer):
      return self.sinkpad.push(buffer)

    def eventfunc(self, pad, event):
      return self.sinkpad.push(buffer)

gobject.type_register(TestFilter)
