Member Function Documentation

apply_colorspace()

void platf::dxgi::d3d_base_encode_device::apply_colorspace ( const ::video::sunshine_colorspace_t & colorspace )

inline

Apply the configured colorspace metadata to the active frame.

Parameters

colorspace

Colorimetry information used for conversion or encoding.

convert()

int platf::dxgi::d3d_base_encode_device::convert ( platf::img_t & img_base )

inline

Convert a captured D3D image into encoder input textures.

Parameters

img_base

D3D image supplied by the capture backend.

Returns

Conversion status.

create_black_texture_for_rtv_clear()

shader_res_t platf::dxgi::d3d_base_encode_device::create_black_texture_for_rtv_clear ( )

inline

Create black texture for rtv clear.

Returns

Created black texture for rtv clear object or status.

init()

int platf::dxgi::d3d_base_encode_device::init ( std::shared_ptr< platf::display_t > display, adapter_t::pointer adapter_p, pix_fmt_e pix_fmt )

inline

Initialize shared D3D conversion resources for the encoder.

Parameters

display	Display object or identifier associated with the operation.
adapter_p	Adapter p.
pix_fmt	Sunshine pixel format to convert or allocate for.

Returns

0 on success; nonzero or negative platform status on failure.

init_output()

int platf::dxgi::d3d_base_encode_device::init_output ( ID3D11Texture2D * frame_texture, int width, int height )

inline

Create D3D11 output textures, views, and shaders for frame conversion.

Parameters

frame_texture	Frame texture.
width	Frame or display width in pixels.
height	Frame or display height in pixels.

Returns

0 when output resources are initialized; nonzero on D3D failure.

initialize_image_context()

int platf::dxgi::d3d_base_encode_device::initialize_image_context ( const img_d3d_t & img, encoder_img_ctx_t & img_ctx )

inline

Initialize encoder-side D3D resources for a captured image.

Parameters

img	Image or frame object to read from or populate.
img_ctx	Cached encoder resources associated with the image ID.

Returns

0 when the shared texture is opened and bound; nonzero on D3D failure.
