  GStreamer | gst-plugins | 1.0.1

           Summary: videoflip causes critical errors in gstreamer 1.0
    Classification: Platform
           Product: GStreamer
           Version: 1.0.1
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: claudio at cloudzilla.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


While using the following pipeline I get a spew of critical errors and I can't
figure out if this is due to a gstreamer bug or an issue with my pipeline:

$ gst-launch-1.0 tcpserversrc port=5503 ! videoparse format=11 width=300
height=200 framerate=20/1 ! videoconvert ! videoflip method=3 ! autovideosink

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
(gst-launch-1.0:21259): GStreamer-CRITICAL **: gst_segment_to_stream_time:
assertion `segment->format == format' failed
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
(gst-launch-1.0:20617): GStreamer-CRITICAL **: gst_segment_to_stream_time:
assertion `segment->format == format' failed
(gst-launch-1.0:20617): GStreamer-CRITICAL **: gst_segment_to_stream_time:
assertion `segment->format == format' failed
(gst-launch-1.0:20617): GStreamer-CRITICAL **: gst_segment_to_stream_time:
assertion `segment->format == format' failed
...

Interestingly, the video is shown correctly despite the critical errors.
If I remove the videoflop element, then the critical errors disappear.

The problem doesn't reproduce on gstreamer-0.10, where the following pipeline
works fine with no critical errors:

$ gst-launch tcpserversrc port=5503 ! videoparse format=10 width=300 height=200
framerate=20/1 ! ffmpegcolorspace ! videoflip method=3 ! autovideosink


My setup is Ubuntu 12.10 (desktop) with the gstreamer1.0-* and gstreamer0.10-*
packages installed:

$ gst-launch-1.0 --version
gst-launch-1.0 version 1.0.1
GStreamer 1.0.1

$ gst-launch --version
gst-launch-0.10 version 0.10.36
GStreamer 0.10.36
