Subject: [PATCH 13/18] Add directviv to glimagesink to improve playback
 performance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1.Add a physical buffer uploader in glupload plugin and using viv direct
  texture to bind physical continious buffer with texture to avoid memory
  copy from videobuffer to texture to gain good performance.
2.Reduce glimagesink load latency by override glimagesink ALLOCATION query to
  avoid memory copy.

Upstream-Status: Inappropriate [i.MX specific]
