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