           Summary: dv1394src delivers stuttering video/audio

            Status: UNCONFIRMED

        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: paul at luon.net

     GNOME version: 2.13/2.14
   GNOME milestone: Unspecified


When using the dv1394src in a pipeline that is directly displayed leads to some
synchronization problems that leads to 1fps-like displaying.  The same holds
also for the sound, the audiosink immediately stop.

This may be a result of the start timestamp errors that the dv1394src reports:

% gst-launch --gst-debug-level=5 -vt dv1394src ! dvdemux name="demux" ! dvdec !
xvimagesink  2>&1  | egrep -i 'invalid'
