  GStreamer | gst-plugins-good | Ver: 0.10.20
           Summary: Seek bugs when playing rtsp video in m.youtube.com
           Product: GStreamer
           Version: 0.10.20
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: chao.zhang at access-company.com

     GNOME version: 2.19/2.20
   GNOME milestone: Unspecified


Please describe the problem:
1. Seek fails when playing rtsp video in m.youtube.com. Rtspsrc sends a `PLAY'
method which includes a `Range' header to implement seeking but youtube
requires `PAUSE' first. In short words, we should send `PAUSE', then `PLAY' to
make seek works. Send `PLAY' directly will make youtube server responses a bad
request.
2. I use `gst_element_seek(pipeline, 1.0, GST_FORMAT_TIME, GST_SEEK_FLAG_FLUSH,
GST_SEEK_TYPE_SET, seek_position, GST_SEEK_TYPE_NONE, GST_CLOCK_TIME_NONE)' to
perform the seek. Seek works but the return value of this call is FALSE.

Steps to reproduce:
1. Use rtspsrc to play the movie in m.youtube.com then seek.

Actual results:
Seek fails and gst_element_seek returns FALSE

Expected results:
gst_element_seek returns TRUE and the seeking is correct

Does this happen every time?
Yes
