           Summary: schroenc + gst-rtsp-server results in out-of-sync
                    audio and video streams
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: fabian.deutsch at gmx.de
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


If the following pipeline is used with test-launch (example part of
gst-rtsp-server)
./test-launch "( v4l2src do-timestamp=true ! videorate ! aspectratiocrop
aspect-ratio=16/9 ! videoscale !
video/x-raw-yuv,width=640,height=360,framerate=12/1 ! schroenc
force-profile=vc2_main quality=8 queue-depth=5 ! queue ! rtpgstpay pt=96
name=pay0   pulsesrc do-timestamp=true ! flacenc ! queue ! rtpgstpay pt=97
name=pay1 )"
the resulting video stream on the client side is out of sync with the
corresponding audio stream.

If the schroenc element is replaced with some different encoder, e.g. vp8enc,
this problem does not appear.
