            Bug ID: 779145
           Summary: dmabuf export from vaapi encoders fails
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gstreamer-vaapi
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: scott.d.phillips at intel.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
                CC: bsreerenj at gmail.com, vjaquez at igalia.com
     GNOME version: ---

Example pipeline:

v4l2src io-mode=dmabuf-import ! video/x-raw,format=YUY2 ! vaapijpegenc !
fakesink

The cause here is that the vaSurface's provided by vaapijpegenc still have the
derived image existing. This causes vaBeginPicture to fail with a "surface
busy" error.
