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 * - Encoder (H264, HEVC, JPEG, MPEG2, VP8, VP9)
116 * - \ref api_enc_h264
117 * - \ref api_enc_hevc
118 * - \ref api_enc_jpeg
119 * - \ref api_enc_mpeg2
122 * - Decoder (HEVC, JPEG, VP8, VP9)
123 * - \ref api_dec_hevc
124 * - \ref api_dec_jpeg
130 * - \ref api_fei_h264
131 * - \ref api_fei_hevc
135 * \defgroup api_core Core API
143 The VA API is intended to provide an interface between a video decode/encode/processing
144 application (client) and a hardware accelerator (server), to off-load
145 video decode/encode/processing operations from the host to the hardware accelerator at various
148 The basic operation steps are:
150 - Negotiate a mutually acceptable configuration with the server to lock
151 down profile, entrypoints, and other attributes that will not change on
152 a frame-by-frame basis.
153 - Create a video decode, encode or processing context which represents a
154 "virtualized" hardware device
155 - Get and fill the render buffers with the corresponding data (depending on
156 profiles and entrypoints)
157 - Pass the render buffers to the server to handle the current frame
159 Initialization & Configuration Management
161 - Find out supported profiles
162 - Find out entrypoints for a given profile
163 - Find out configuration attributes for a given profile/entrypoint pair
164 - Create a configuration for use by the application

481 * \brief Decode processing support. Read/write.
483 * This attribute determines if the driver supports video processing
484 * with decoding using the decoding context in a single call, through
485 * vaGetConfigAttributes(); and if the user may use this feature,
486 * through vaCreateConfig(), if the driver supports the user scenario.
487 * The user will essentially create a regular decode VAContext. Therefore,
488 * the parameters of vaCreateContext() such as picture_width, picture_height
489 * and render_targets are in relation to the decode output parameters
490 * (not processing output parameters) as normal.
491 * If this attribute is not set by the user then it is assumed that no
492 * extra processing is done after decoding for this decode context.
494 * Since essentially the application is creating a decoder config and context,
495 * all function calls that take in the config (e.g. vaQuerySurfaceAttributes())
496 * or context are in relation to the decoder, except those video processing
497 * function specified in the next paragraph.
499 * Once the decode config and context are created, the user must further
500 * query the supported processing filters using vaQueryVideoProcFilters(),
501 * vaQueryVideoProcFilterCaps(), vaQueryVideoProcPipelineCaps() by specifying
502 * the created decode context. The user must provide processing information
503 * and extra processing output surfaces as "additional_outputs" to the driver
504 * through VAProcPipelineParameterBufferType. The render_target specified
505 * at vaBeginPicture() time refers to the decode output surface. The
506 * target surface for the output of processing needs to be a different
507 * surface since the decode process requires the original reconstructed buffer.
508 * The “surface” member of VAProcPipelineParameterBuffer should be set to the
