            Bug ID: 764363
           Summary: videoaggregator: Setting aspect ratio crops the frame
    Classification: Platform
           Product: GStreamer
           Version: 1.6.0
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: slomo at coaxion.net

        Depends on: 756207
     GNOME version: ---

+++ This bug was initially created as a clone of Bug #756207 +++

That last patch breaks pipeline like:

gst-launch-1.0 videotestsrc num-buffers=30 pattern=solid-color
foreground-color=0 ! videoconvert ! video/x-raw,format=RGBA !  textoverlay
text='test yes yo' color=5293848812 valignment=center font-desc='Serif Italic
36' ! compositor !  videoconvert ! autovideosink

where the compositor should force an ALPHA channel downstream as upstream has
one so that. Currently instead of showing the compositor checkerboard as
expected it shows the text over a black frame.... which totally breaks titles
in pitivi.
