49.5.2. Warp IP Software Code Examples

UHD 60 Hz Workflow example

This example shows the workflow and basic warp software usage of the C++ source code to generate and apply 15 degree rotation warp. The example is for 3840x2160@60Hz video, which requires the processing to be split between two warp engines. The frame buffer and warp coefficient base addresses in the example are arbitrary. Actual values depend on a particular system design. 

const uint32_t FRAMEBUF_BASE_ADDR	= 0x80000000;
const uint32_t COEF_BASE_ADDR		= 0xa0000000;
const uint32_t SKIP_RAM_PAGE		= 0;
intel_vvp_warp_base_t base			= INTEL_VVP_WARP_BASE;
intel_vvp_warp_instance_t wrp0;

// Initialize driver instance
intel_vvp_warp_init_instance(&wrp0, base);

// Create warp channel
intel_vvp_warp_channel_t* ch0 = intel_vvp_warp_create_double_channel(&wrp0, 0, 0, 1, 0);

Warp mesh usage

Define required warp using the WarpMesh object. The example shows the simplest case of 1:1 (unity) warp for a 3840x2160 video. 

intel_vvp_warp::WarpMesh mesh{3840, 2160};

for(uint32_t v = 0; v < mesh.GetVNodes(); ++v)
{
	mesh_node_t* node = mesh.GetRow(v);

	for(uint32_t h = 0; h < mesh.GetHNodes(); ++h)
	{
					  node->_x = (h * mesh.GetStep()) << 4;
		  node->_y = (v * mesh.GetStep()) << 4;
	}
}

Mesh coordinates use the least significant four bits as fractional part for subpixel precision. In the example above the fractional part is always 0. Store subpixel positions in the following way: 

mesh_node_t* node = mesh.GetRow(v);
…
float pos_x = 10.6f;
node->_x = static_cast<int32_t>(roundf(pos_x * 16.0f));

Easy warp example

When you turn on Easy warp you can rotate the input video to 0, 90, 180 or 270 degrees or mirror the video without the need of transform mesh and associated warp data. 

const uint32_t FRAMEBUF_BASE_ADDR	= 0x80000000;
const uint32_t width			= 1920;
const uint32_t height			= 1080;
intel_vvp_warp_base_t base		= INTEL_VVP_WARP_BASE;
intel_vvp_warp_instance wrp0;

// Initialize driver instance
intel_vvp_warp_init_instance(&wrp0, base);

// Allocate Easy warp channel
intel_vvp_warp_channel_t* ch0 = intel_vvp_warp_create_easy_warp_channel(&wrp0, 0, 0);
assert(ch0 != NULL);
assert(intel_vvp_warp_check_easy_warp_capable(ch0) == 0);

// Configure channel
intel_vvp_warp_channel_config_t cfg;

// Configure in 4K, RGB Full colourspace
cfg.ram_addr = FRAMEBUF_BASE_ADDR;
cfg.cs = ERGB_FULL;
cfg.width_input = width;
cfg.height_input = height;
cfg.width_output = width;
cfg.height_output = height;
cfg.lfr = 0;

intel_vvp_warp_configure_channel(ch0, &cfg);	

// Mirror input video
// Enable video bypass, keep original resolution
intel_vvp_warp_bypass(ch0, 1, 0, width, height);
// Configure Easy warp mirror
intel_vvp_warp_set_easy_warp(ch0, 0x4);

// Rotate input video 90 degrees CCW
// Enable video bypass, flip input width and height
intel_vvp_warp_bypass(ch0, 1, 0, height, width);
// Configure Easy warp rotation
intel_vvp_warp_set_easy_warp(ch0, 0x01);	

// Release warp channel
intel_vvp_warp_free_channel(ch0);
assert(wrp0.num_engines > 0);

Warp latency parameters generation example

The example shows how to generate recommended minimum latency parameters for a given video transformation. These parameters are necessary to configure video pipeline for low latency operation. 

// Example video and system clock
static constexpr uint32_t EXAMPLE_CLOCK	= 300000000;
// UHD video dimensions
static constexpr uint32_t WIDTH_UHD		= 3840;
static constexpr uint32_t HEIGHT_UHD		= 2160;
static constexpr uint32_t FULL_HEIGHT_UHD	= 2250;
// Output frame rate x100
static constexpr uint32_t OUTPUT_FRAME_RATE	= 6000;

// In this example system and video clock are the same
const uint32_t system_clock = EXAMPLE_CLOCK;
const uint32_t video_clock = EXAMPLE_CLOCK;

// Warp channel
intel_vvp_warp_channel_t* ch0{nullptr};

// Allocate and initialize a warp channel here
//	...
//////////////////////////////////////////////

// Generate a 4K mesh for 5 degree CCW rotation
WarpConfigurator configurator{WarpDataHelper::GetHwContext(ch0)};

configurator.SetInputResolution(WIDTH_UHD, HEIGHT_UHD);
configurator.SetOutputResolution(WIDTH_UHD, HEIGHT_UHD);
configurator.Reset();
configurator.SetRotate(5.0f);

WarpMeshSet mesh_set{configurator.GenerateMeshFromFixed()};

// Parameters required for warp data generation
WarpDataContext ctx{
	WarpDataHelper::GetHwContext(ch0),
	WIDTH_UHD, HEIGHT_UHD,
	WIDTH_UHD, HEIGHT_UHD
};
			
WarpDataGenerator data_generator;

WarpDataPtr user_data = data_generator.GenerateData(ctx, mesh_set);

// Obtain latency params for the configured warp
WarpLatencyParams latency_params = data_generator.GenerateLatencyParams(ctx, user_data, system_clock, video_clock, FULL_HEIGHT_UHD, OUTPUT_FRAME_RATE);

// Upload and apply generated warp data here
// …
// intel_vvp_warp_apply_transform(ch0, …);
// …

// Pass on “output_latency” to the driver
intel_vvp_warp_set_output_latency(ch0, latency_params._output_latency);

// The “total_latency” member represents the recommended minimum offset
// between the input and output frames
// The value is in axi4s_vid_out_0_clock clock cycles
// Use the this parameter to configure the rest of the video pipeline
// as appropriate
//
//	latency_params._total_latency;
//assert(wrp0.num_engines > 0);
