splitmuxsink arbitrary close

[cottrelld]

The sending of the EOS closes out the file if I just sent it by itself
without the block (Half way there!).  But I can't get the sink in order to
place the probe and capture the callback.  How do you obtain the sink pad
on the splitmuxsink?  I get null back from gst_element_get_static_pad in
the code below.

>> What I would do is to place a probe on the splitmuxsink sink pad, with
the flag GST_PAD_PROBE_TYPE_EVENT_DOWNSTREAM and then verify the EOS in the
callback with

(Note, I also tried to obtain the actual sink in hopes of getting the pad
off that, but the sink property is only the provided sink. )


*void PipelineManager::stopPipeline_writerImpl()*
{
  g_print("stopPipeline_writerImpl, stopping\n");

  if (!gPipelineMgr->m_writeSink) {
    g_critical("stopPipeline_writerImpl: m_writeSink is NULL!!\n");
    exit(-1);
  }

  // Block all transmissions past m_queueWriterTee
  GstPad* writerSinkPad =
gst_element_get_static_pad(gPipelineMgr->m_writeSink, "sink");
  if (!writerSinkPad) {
    g_critical("stopPipeline_writerImpl: Could not obtain the writer
sinkpad!!\n"); // <---- fails here!
    exit(-1);
  }

  gst_pad_add_probe(writerSinkPad,
                    (GstPadProbeType)(GST_PAD_PROBE_TYPE_EVENT_DOWNSTREAM),
                    writer_eos_cb,
                    m_loop,
                    NULL);
  gst_object_unref(writerSinkPad);

  // Send an EOS on the queue
  GstPad* queueSinkPad = gst_element_get_static_pad
(gPipelineMgr->m_queueWriterTee, "sink");
  gst_pad_send_event(queueSinkPad, gst_event_new_eos ());
  gst_object_unref(queueSinkPad);

  g_print("stopPipeline_writerImpl, done...\n");
}


Thanks again for your help!
