Restart Pipeline

[killerrats]

I found out that if I grabbed out the element from the pipeline and assigned
it like i just created it in the beginning it will reset the depays (example
below). the only problem is that it gets to a point where it says internal
stream error after awhile. I don't understand that.

if i don't do this it will come up with the cannot link the audio and video
pads to each of the depays. the first marks are from the "pad-removed"
signal which show the pads are unlinked from the previous play. marks below
are the new ones coming in after a restart.

GstElement* pipe,* source,* depay;

void unlink();

int main()
{
    GMainLoop* loop;

    pipe = gst_pipeline_new("pipeline");
    source = gst_element_factory_make("rtspsrc", "source");
    depay =  = gst_element_factory_make("rtph264depay", "depay");

    gst_element_set_state(pipe, GST_STATE_PLAYING);

    do
    {
      g_main_loop_run(loop);
      unlink();
    }
}

void unlink()
{
     depay = gst_bin_get_by_name(GST_BIN(pipe), "depay");
     
     gst_element_set_state(pipe, GST_STATE_NULL);

     gst_bin_remove(GST_BIN(pipe),depay);

     gst_bin_add(GST_BIN(pipe),depay);
}
