            Bug ID: 747707
           Summary: applemedia: expose GstCoreMediaMeta to app
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: Normal
         Component: gst-plugins-base
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: ilya.konstantinov at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

An OS X and iOS app might use appsink to get resulting GstBuffers from a
pipeline containing applemedia elements. Furthermore, it can wish to access
(and retain) the underlying CMSampleBufferRef or CMPixelBufferRef, as they're
needed:

 1) to work with AVFoundation, Core Video and Core Image 

 2) for GL rendering done by app

How can we expose some of the applemedia stuff (e.g. coremediabuffer.h) as API?
