decodebin2

[Steffen.Roeber at hella.com]

Hi
I'm usng a pipeline that contains a filesrc, a decodebin, an appsink and 
some other elements. What I want to get is the duration of  the current 
element.
For this I'm using
GstQuery *frameDuration = gst_query_new_duration(GST_FORMAT_DEFAULT);
gst_element_query(reinterpret_cast<GstElement *>(m_pipeline), 
frameDuration);
sint64 temp = 0;
gst_query_parse_duration(frameDuration, 0, &temp);

I have two problems with this approach. First, this works only after I 
called
GstBuffer *buffer = gst_app_sink_pull_buffer(m_appSink);
which is very annoying.
And the second problem is that it does not work at all if I change the 
filename of the filesrc:
gst_element_set_state(reinterpret_cast<GstElement *>(m_pipeline), 
GST_STATE_NULL);
setProperty(reinterpret_cast<GObject *>(aviSrc), "location", filename);
...

The duration is always the same for each new filename.
What could I do?

Kind Regards
