           Summary: gstreamer 1.0 ignores v4l2 quirk flags; video
                    upside-down
    Classification: Platform
           Product: GStreamer
           Version: 1.x
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: grawity at gmail.com

     GNOME version: ---


My Asus laptop's webcam is mounted upside-down (which seems to be rather
common), and the v4l-utils libraries have a flag [1] to handle this issue, so
programs using gstreamer-0.10 (such as Cheese) display the video correctly.

However, the v4l flags are completely ignored in gstreamer-1.0 and it again
displays everything upside-down, unless I manually LD_PRELOAD the
"v4l2convert.so" library (which is provided by v4l-utils to make broken
programs work).

Normal:
# unset LD_PRELOAD
# gst-launch-0.10 v4l2src ! autovideosink

Upside-down:
# unset LD_PRELOAD
# gst-launch-1.0 v4l2src ! autovideosink

Normal again:
# export LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so
# gst-launch-1.0 v4l2src ! autovideosink
