            Bug ID: 744246
           Summary: gl: Broken VideoAlignment handling?
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: slomo at coaxion.net
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

When using latest GIT master on Android with glimagesink and avviddec_h264, the
following crash usually happens. Putting a tee before glimagesink (which makes
the ALLOCATION query fail and fall back to not use VideoAlignment or anything)
makes it work again.

Crash is a SIGBUS btw, so we probably need to align memory differently somehow
to make libav happy.
