/**
* \defgroup api_vpp Video processing API
*
* @{
*
* The video processing API uses the same paradigm as for decoding:
* - Query for supported filters;
* - Set up a video processing pipeline;
* - Send video processing parameters through VA buffers.
*
* \section api_vpp_caps Query for supported filters
*
* Checking whether video processing is supported can be performed
* with vaQueryConfigEntrypoints() and the profile argument set to
* #VAProfileNone. If video processing is supported, then the list of
* returned entry-points will include #VAEntrypointVideoProc.
*
* \code
* VAEntrypoint *entrypoints;
* int i, num_entrypoints, supportsVideoProcessing = 0;
*
* num_entrypoints = vaMaxNumEntrypoints();
* entrypoints = malloc(num_entrypoints * sizeof(entrypoints[0]);
* vaQueryConfigEntrypoints(va_dpy, VAProfileNone,
* entrypoints, &num_entrypoints);
*
* for (i = 0; !supportsVideoProcessing && i < num_entrypoints; i++) {
* if (entrypoints[i] == VAEntrypointVideoProc)
* supportsVideoProcessing = 1;
* }
* \endcode
*
* Then, the vaQueryVideoProcFilters() function is used to query the
* list of video processing filters.
*
* \code
* VAProcFilterType filters[VAProcFilterCount];
* unsigned int num_filters = VAProcFilterCount;
*
* // num_filters shall be initialized to the length of the array
* vaQueryVideoProcFilters(va_dpy, vpp_ctx, &filters, &num_filters);
* \endcode
*
* Finally, individual filter capabilities can be checked with
* vaQueryVideoProcFilterCaps().
*
* \code
* VAProcFilterCap denoise_caps;
* unsigned int num_denoise_caps = 1;
* vaQueryVideoProcFilterCaps(va_dpy, vpp_ctx,
* VAProcFilterNoiseReduction,
* &denoise_caps, &num_denoise_caps
* );
*
* VAProcFilterCapDeinterlacing deinterlacing_caps[VAProcDeinterlacingCount];
* unsigned int num_deinterlacing_caps = VAProcDeinterlacingCount;
* vaQueryVideoProcFilterCaps(va_dpy, vpp_ctx,
* VAProcFilterDeinterlacing,
* &deinterlacing_caps, &num_deinterlacing_caps
* );
* \endcode
*
* \section api_vpp_setup Set up a video processing pipeline
*
* A video processing pipeline buffer is created for each source
* surface we want to process. However, buffers holding filter
* parameters can be created once and for all. Rationale is to avoid
* multiple creation/destruction chains of filter buffers and also
* because filter parameters generally won't change frame after
* frame. e.g. this makes it possible to implement a checkerboard of
* videos where the same filters are applied to each video source.
*
* The general control flow is demonstrated by the following pseudo-code:
* \code
* // Create filters
* VABufferID denoise_filter, deint_filter;
* VABufferID filter_bufs[VAProcFilterCount];
* unsigned int num_filter_bufs;
*
* for (i = 0; i < num_filters; i++) {
* switch (filters[i]) {
* case VAProcFilterNoiseReduction: { // Noise reduction filter
* VAProcFilterParameterBuffer denoise;
* denoise.type = VAProcFilterNoiseReduction;
* denoise.value = 0.5;
* vaCreateBuffer(va_dpy, vpp_ctx,
* VAProcFilterParameterBufferType, sizeof(denoise), 1,
* &denoise, &denoise_filter
* );
* filter_bufs[num_filter_bufs++] = denoise_filter;
* break;
* }
*
* case VAProcFilterDeinterlacing: // Motion-adaptive deinterlacing
* for (j = 0; j < num_deinterlacing_caps; j++) {
* VAProcFilterCapDeinterlacing * const cap = &deinterlacing_caps[j];
* if (cap->type != VAProcDeinterlacingMotionAdaptive)
* continue;
*
* VAProcFilterParameterBufferDeinterlacing deint;
* deint.type = VAProcFilterDeinterlacing;
* deint.algorithm = VAProcDeinterlacingMotionAdaptive;
* vaCreateBuffer(va_dpy, vpp_ctx,
* VAProcFilterParameterBufferType, sizeof(deint), 1,
* &deint, &deint_filter
* );
* filter_bufs[num_filter_bufs++] = deint_filter;
* }
* }
* }
* \endcode
*
* Once the video processing pipeline is set up, the caller shall check the
* implied capabilities and requirements with vaQueryVideoProcPipelineCaps().
* This function can be used to validate the number of reference frames are
* needed by the specified deinterlacing algorithm, the supported color
* primaries, etc.
* \code
* // Create filters
* VAProcPipelineCaps pipeline_caps;
* VASurfaceID *forward_references;
* unsigned int num_forward_references;
* VASurfaceID *backward_references;
* unsigned int num_backward_references;
* VAProcColorStandardType in_color_standards[VAProcColorStandardCount];
* VAProcColorStandardType out_color_standards[VAProcColorStandardCount];
*
* pipeline_caps.input_color_standards = NULL;
* pipeline_caps.num_input_color_standards = ARRAY_ELEMS(in_color_standards);
* pipeline_caps.output_color_standards = NULL;
* pipeline_caps.num_output_color_standards = ARRAY_ELEMS(out_color_standards);
* vaQueryVideoProcPipelineCaps(va_dpy, vpp_ctx,
* filter_bufs, num_filter_bufs,
* &pipeline_caps
* );
*
* num_forward_references = pipeline_caps.num_forward_references;
* forward_references =
* malloc(num__forward_references * sizeof(VASurfaceID));
* num_backward_references = pipeline_caps.num_backward_references;
* backward_references =
* malloc(num_backward_references * sizeof(VASurfaceID));
* \endcode
*
* \section api_vpp_submit Send video processing parameters through VA buffers
*
* Video processing pipeline parameters are submitted for each source
* surface to process. Video filter parameters can also change, per-surface.
* e.g. the list of reference frames used for deinterlacing.
*
* \code
* foreach (iteration) {
* vaBeginPicture(va_dpy, vpp_ctx, vpp_surface);
* foreach (surface) {
* VARectangle output_region;
* VABufferID pipeline_buf;
* VAProcPipelineParameterBuffer *pipeline_param;
*
* vaCreateBuffer(va_dpy, vpp_ctx,
* VAProcPipelineParameterBuffer, sizeof(*pipeline_param), 1,
* NULL, &pipeline_buf
* );
*
* // Setup output region for this surface
* // e.g. upper left corner for the first surface
* output_region.x = BORDER;
* output_region.y = BORDER;
* output_region.width =
* (vpp_surface_width - (Nx_surfaces + 1) * BORDER) / Nx_surfaces;
* output_region.height =
* (vpp_surface_height - (Ny_surfaces + 1) * BORDER) / Ny_surfaces;
*
* vaMapBuffer(va_dpy, pipeline_buf, &pipeline_param);
* pipeline_param->surface = surface;
* pipeline_param->surface_region = NULL;
* pipeline_param->output_region = &output_region;
* pipeline_param->output_background_color = 0;
* if (first surface to render)
* pipeline_param->output_background_color = 0xff000000; // black
* pipeline_param->filter_flags = VA_FILTER_SCALING_HQ;
* pipeline_param->filters = filter_bufs;
* pipeline_param->num_filters = num_filter_bufs;
* vaUnmapBuffer(va_dpy, pipeline_buf);
*
* // Update reference frames for deinterlacing, if necessary
* pipeline_param->forward_references = forward_references;
* pipeline_param->num_forward_references = num_forward_references_used;
* pipeline_param->backward_references = backward_references;
* pipeline_param->num_backward_references = num_bacward_references_used;
*
* // Apply filters
* vaRenderPicture(va_dpy, vpp_ctx, &pipeline_buf, 1);
* }
* vaEndPicture(va_dpy, vpp_ctx);
