           Summary: "clock problem" happend when doing seek in avidemux
           Product: GStreamer
           Version: 0.10.12
          Platform: Other

Please describe the problem:
I’ve added seek function in a sample player, but seems the seek function
failed. The playback resumed at the same pause point.
I tried the following 2 functions, same error message. Any inputs?
    if (!gst_element_seek (player_status->demux, 1.0, GST_FORMAT_TIME,
GST_SEEK_FLAG_FLUSH, GST_SEEK_TYPE_SET, time_nanoseconds,           
GST_SEEK_TYPE_NONE, GST_CLOCK_TIME_NONE)) {
        g_print("Seek failed!\n");
    }

   if (!gst_element_seek_simple(player_status->demux, GST_FORMAT_TIME,
GST_SEEK_FLAG_FLUSH, time_nanoseconds)) {
        g_print("Seek failed!\n");
   }

Here demux is gstreamer official "avidemux". I didn't use the "pipeline" in the
first argument because it does not work. One thing to be mentioned is that I
use 3rd party decoders, video/audio sink and clock. The 3rd party clock is
already set to the whole pipeline.
Error message:
--------------------------------------------------------------------------
Warning: Internal GStreamer error: clock problem.  Please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.


Steps to reproduce:
1. Wrote application code in sample player to link all necessary elements
2. Start the sample player, call the seek function to jump forward.



Actual results:
The playback paused with error message, after a while, the player resumed 
playback at the pause point.

Expected results:
I expect the playback jump to the seek point specified by "time_nanoseconds"

Does this happen every time?
Yes
