Here is the output from ffmpeg -i filename.mpg:

Here is the output from gst_element_query_duration:

3:37:14.178723991

As you can see there a difference of more than 20 minutes.  I looked for any
existing bugs, but did not find anything.  Here is how it is implemented:

        case GDK_k:
        {

                gint64 dur_ns;
                GstFormat format;

                format = GST_FORMAT_TIME;

                gst_element_query_duration(pipeline,&format,&dur_ns);
                g_print ("%" GST_TIME_FORMAT "\n", GST_TIME_ARGS (dur_ns));

                return TRUE;


        }
        break;

Am I missing something?  I can't attach the file as it is ~25 GB.  Is there a
simple way to trim off a couple minutes of the file without changing the
encoding?
