            Bug ID: 767104
           Summary: applemedia: vtenc: Register a hardware-only
                    vtenc_h264_hw element on OSX
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: hfink at toolsonair.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

We ran into the use case where we'd like to fall back to x264enc if vtenc
can't actually encode using the hardware encoder on OSX. This patch adds a
vtenc_h264_hw element that would fail to negotiate if hardware resources
couldn't be acquired. We can then catch this, and replace vtenc_h264_hw with
v264enc (which is much faster than the vtenc_h264 software encoder).
