+2014-09-xx - xxxxxxx - lavu 54.04.0 - pixdesc.h
+  Add API to return the name of frame and context color properties.

 2014-09-xx - xxxxxxx - lavc 56.2.0 - vdpau.h
   Add av_vdpau_bind_context(). This function should now be used for creating
   (or resetting) a AVVDPAUContext instead of av_vdpau_alloc_context().
