+ * \mainpage Video Acceleration (VA) API
+ *
+ * \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
+ */
+
+/**
+ * \defgroup api_core Core API

+
+/**
+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
