  GStreamer | gst-plugins-bad | Ver: 0.10.12
           Summary: GStreamer DVB tuning too quick for some devices
           Product: GStreamer
           Version: 0.10.12
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: austin.lund at gmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.25/2.26
   GNOME milestone: Unspecified


Please describe the problem:
The dvb source in gstreamer-plugins-bad goes from the FE_SET_FRONTEND ioctl to
the FE_READ_STATUS ioctls too quickly.  My device (Afatech AF9013 DVB-T) takes
about 1 second to tune to a channel.  The way gstdvbsrc.c is coded at the
moment in gst_dvbsrc_tune() it only allows for about 500ms before it gives up.  

By increasing the length of time waited at the FE_READ_STATUS cycle, things are
slower but at least my device does eventually tune.  I've noted that other
players use a poll() to perform this step instead of a fixed length of time to
tune.

Steps to reproduce:
1. Get a DVB device that takes > 500ms to tune.
2. Run: gst-launch playbin 'uri=dvb://BLAH'


Actual results:
Gives up trying to tune very quickly and returns.

Expected results:
Tunes to selected station

Does this happen every time?
Yes
