* \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, AV1)
* - \ref api_dec_hevc
* - \ref api_dec_jpeg
* - \ref api_dec_vp8
* - \ref api_dec_vp9
* - \ref api_dec_av1
* - \ref api_vpp
* - \ref api_prot
* - FEI (H264, HEVC)
* - \ref api_fei
* - \ref api_fei_h264
* - \ref api_fei_hevc
*
* \section threading Multithreading Guide
* All VAAPI functions implemented in libva are thread-safe. For any VAAPI
* function that requires the implementation of a backend (e.g. hardware driver),
* the backend must ensure that its implementation is also thread-safe. If the
* backend implementation of a VAAPI function is not thread-safe then this should
* be considered as a bug against the backend implementation.
*
* It is assumed that none of the VAAPI functions will be called from signal
* handlers.
*
* Thread-safety in this context means that when VAAPI is being called by multiple
* concurrent threads, it will not crash or hang the OS, and VAAPI internal
* data structures will not be corrupted. When multiple threads are operating on
* the same VAAPI objects, it is the application's responsibility to synchronize
* these operations in order to generate the expected results. For example, using
* a single VAContext from multiple threads may generate unexpected results.
*
* Following pseudo code illustrates a multithreaded transcoding scenario, where
* one thread is handling the decoding operation and another thread is handling
* the encoding operation, while synchronizing the use of a common pool of
* surfaces.
*
* \code
* // Initialization
* dpy = vaGetDisplayDRM(fd);
* vaInitialize(dpy, ...);
*
* // Create surfaces required for decoding and subsequence encoding
* vaCreateSurfaces(dpy, VA_RT_FORMAT_YUV420, width, height, &surfaces[0], ...);
*
* // Set up a queue for the surfaces shared between decode and encode threads
* surface_queue = queue_create();
*
* // Create decode_thread
* pthread_create(&decode_thread, NULL, decode, ...);
*
* // Create encode_thread
* pthread_create(&encode_thread, NULL, encode, ...);
*
* // Decode thread function
* decode() {
* // Find the decode entrypoint for H.264
* vaQueryConfigEntrypoints(dpy, h264_profile, entrypoints, ...);
*
* // Create a config for H.264 decode
* vaCreateConfig(dpy, h264_profile, VAEntrypointVLD, ...);
*
* // Create a context for decode
* vaCreateContext(dpy, config, width, height, VA_PROGRESSIVE, surfaces,
* num_surfaces, &decode_context);
*
* // Decode frames in the bitstream
* for (;;) {
* // Parse one frame and decode
* vaBeginPicture(dpy, decode_context, surfaces[surface_index]);
* vaRenderPicture(dpy, decode_context, buf, ...);
* vaEndPicture(dpy, decode_context);
* // Poll the decoding status and enqueue the surface in display order after
* // decoding is complete
* vaQuerySurfaceStatus();
* enqueue(surface_queue, surface_index);
* }
* }
*
* // Encode thread function
* encode() {
* // Find the encode entrypoint for HEVC
* vaQueryConfigEntrypoints(dpy, hevc_profile, entrypoints, ...);
*
* // Create a config for HEVC encode
* vaCreateConfig(dpy, hevc_profile, VAEntrypointEncSlice, ...);
*
* // Create a context for encode
* vaCreateContext(dpy, config, width, height, VA_PROGRESSIVE, surfaces,
* num_surfaces, &encode_context);
*
* // Encode frames produced by the decoder
* for (;;) {
* // Dequeue the surface enqueued by the decoder
* surface_index = dequeue(surface_queue);
* // Encode using this surface as the source
* vaBeginPicture(dpy, encode_context, surfaces[surface_index]);
* vaRenderPicture(dpy, encode_context, buf, ...);
* vaEndPicture(dpy, encode_context);
* }
* }
* \endcode

/**
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
