           Summary: [videomixer] needs mode that syncs streams based on
                    timestamps
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: t.i.m at zen.co.uk
         QAContact: gstreamer-bugs at lists.sourceforge.net
      GNOME target: ---
     GNOME version: ---


Currently it only looks at durations, it seems, try:

    gst-launch-0.10 videomixer name=mix ! ffmpegcolorspace ! timeoverlay !
xvimagesink \
        videotestsrc pattern=circular timestamp-offset=10000000000 ! alpha
alpha=0.5 ! mix. \
        videotestsrc ! alpha alpha=0.5 ! mix.


The circular pattern should only show up after 10 seconds have passed, but it
shows up immediately with the current video mixer.
