90 * \section intro Introduction
92 * The main motivation for VA-API (Video Acceleration API) is to
93 * enable hardware accelerated video decode and encode at various
94 * entry-points (VLD, IDCT, Motion Compensation etc.) for the
95 * prevailing coding standards today (MPEG-2, MPEG-4 ASP/H.263, MPEG-4
96 * AVC/H.264, VC-1/VMW3, and JPEG).
98 * VA-API is split into several modules:
100 * - \ref api_enc_core
101 * - \ref api_enc_h264
106 * \defgroup api_core Core API
114 The VA API is intended to provide an interface between a video decode/encode/display
115 application (client) and a hardware accelerator (server), to off-load
116 video decode/encode/display operations from the host to the hardware accelerator at various
119 The basic operation steps are:
121 - Negotiate a mutually acceptable configuration with the server to lock
122 down profile, entrypoints, and other attributes that will not change on
123 a frame-by-frame basis.
124 - Create a decode context which represents a "virtualized" hardware decode
126 - Get and fill decode buffers with picture level, slice level and macroblock
127 level data (depending on entrypoints)
128 - Pass the decode buffers to the server to decode the current frame
130 Initialization & Configuration Management
132 - Find out supported profiles
133 - Find out entrypoints for a given profile
134 - Find out configuration attributes for a given profile/entrypoint pair
135 - Create a configuration for use by the decoder
