102 * \mainpage Video Acceleration (VA) API
104 * \section intro Introduction
106 * The main motivation for VA-API (Video Acceleration API) is to
107 * enable hardware accelerated video decode and encode at various
108 * entry-points (VLD, IDCT, Motion Compensation etc.) for the
109 * prevailing coding standards today (MPEG-2, MPEG-4 ASP/H.263, MPEG-4
110 * AVC/H.264, VC-1/VMW3, and JPEG, HEVC/H265, VP8, VP9) and video pre/post
113 * VA-API is split into several modules:
115 * - \ref api_enc_xxx (xxx = h264, hevc, jpec, mpeg2, vp8, vp9)
116 * - \ref api_dec_xxx (xxx = hevc, jpec, vp8, vp9)
121 * \defgroup api_core Core API
129 The VA API is intended to provide an interface between a video decode/encode/processing
130 application (client) and a hardware accelerator (server), to off-load
131 video decode/encode/processing operations from the host to the hardware accelerator at various
134 The basic operation steps are:
136 - Negotiate a mutually acceptable configuration with the server to lock
137 down profile, entrypoints, and other attributes that will not change on
138 a frame-by-frame basis.
139 - Create a video decode, encode or processing context which represents a
140 "virtualized" hardware device
141 - Get and fill the render buffers with the corresponding data (depending on
142 profiles and entrypoints)
143 - Pass the render buffers to the server to handle the current frame
145 Initialization & Configuration Management
147 - Find out supported profiles
148 - Find out entrypoints for a given profile
149 - Find out configuration attributes for a given profile/entrypoint pair
150 - Create a configuration for use by the application
