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