            Bug ID: 751071
           Summary: applemedia: CMBlockBuffer can be non-contiguous
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Mac OS
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: ilya.konstantinov at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

The function that wraps Apple's CMBlockBuffer --
gst_core_media_buffer_wrap_block_buffer -- makes an incorrect assumption about
CMBlockBuffer being a single memory block, and uses CMBlockBufferGetDataLength
incorrectly.

In fact, they're more like our GstBuffer than GstMemory.
