+Overview 
+
+The VA API is intended to provide an interface between a video decode/encode/display
+application (client) and a hardware accelerator (server), to off-load 
+video decode/encode/display operations from the host to the hardware accelerator at various 
+entry-points.
+
+The basic operation steps are:
+
+- Negotiate a mutually acceptable configuration with the server to lock
+  down profile, entrypoints, and other attributes that will not change on 
+  a frame-by-frame basis.
+- Create a decode context which represents a "virtualized" hardware decode 
+  device
+- Get and fill decode buffers with picture level, slice level and macroblock 
+  level data (depending on entrypoints)
+- Pass the decode buffers to the server to decode the current frame
+
+Initialization & Configuration Management 
+
+- Find out supported profiles
+- Find out entrypoints for a given profile
+- Find out configuration attributes for a given profile/entrypoint pair
+- Create a configuration for use by the decoder
