This method is the only reason for the existence of this class.  This class was
created to clarify the distinction that this method only makes sense in the GPU
process (not in the renderer process, where there are also implementations of
the VDA interface): https://chromiumcodereview.appspot.com/23125014/#msg12

If this interface is going to live in a not-scoped-to-the-gpu-process directory,
and not have any gpu-specific name attached to it, then this method might as
well be added to video_decode_accelerator.h and this file deleted, and with it
the need for media/types?
