-+ *
-+ * \section intro Introduction
-+ *
-+ * The main motivation for VA-API (Video Acceleration API) is to
-+ * enable hardware accelerated video decode and encode at various
-+ * entry-points (VLD, IDCT, Motion Compensation etc.) for the
-+ * prevailing coding standards today (MPEG-2, MPEG-4 ASP/H.263, MPEG-4
-+ * AVC/H.264, VC-1/VMW3, and JPEG, HEVC/H265, VP8, VP9) and video pre/post
-+ * processing
-+ *
-+ * VA-API is split into several modules:
-+ * - \ref api_core
-+ * - Encoder (H264, HEVC, JPEG, MPEG2, VP8, VP9)
-+ * - \ref api_enc_h264
-+ * - \ref api_enc_hevc
-+ * - \ref api_enc_jpeg
-+ * - \ref api_enc_mpeg2
-+ * - \ref api_enc_vp8
-+ * - \ref api_enc_vp9
-+ * - Decoder (HEVC, JPEG, VP8, VP9)
-+ * - \ref api_dec_hevc
-+ * - \ref api_dec_jpeg
-+ * - \ref api_dec_vp8
-+ * - \ref api_dec_vp9
-+ * - \ref api_vpp
-+ * - FEI (H264, HEVC)
-+ * - \ref api_fei
-+ * - \ref api_fei_h264
-+ * - \ref api_fei_hevc

-+Overview
-+
-+The VA API is intended to provide an interface between a video decode/encode/processing
-+application (client) and a hardware accelerator (server), to off-load
-+video decode/encode/processing 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 video decode, encode or processing context which represents a
-+ "virtualized" hardware device
-+- Get and fill the render buffers with the corresponding data (depending on
-+ profiles and entrypoints)
-+- Pass the render buffers to the server to handle 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 application
