  GStreamer | gst-plugins-base | Ver: git
           Summary: ts-offset property of appsink is ineffective
           Product: GStreamer
           Version: git
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: andreas.frisch at multimedia-labs.de

     GNOME version: Unspecified
   GNOME milestone: Unspecified


Please describe the problem:
on my dreambox architecture, the ts-offset of the appsink element influences
the subtitle handover time in no way, when used as text-sink element for a
playbin2 pipeline with e.g. internal mkv subtitles

Steps to reproduce:
1. took wim's playbin-text example 2009-03-23 15:59:36
2. changed it to not quit the main loop on warnings
3. chose a ts-offset of 5*GST_SECOND 
4. crosscompiled it
5. root at dm8000:/testProgs# ./playbin-text
file:///media/hdd/movie/mkv/with_utf8_sub.mkv


Actual results:
** (playbin-text:26660): WARNING **: gstplaysink.c(1224): gen_audio_chain ():

it.

the subtitles are displayed the same exact time as when compiling without
ts-offset

Expected results:
i'd expect the subtitles to be displayed with the correct offset chosen

Does this happen every time?
yes

Other information:
maybe it has to do with the "Failed to configure latency of 0:00:00.000000000"
warning?
