Detailed Description

D3D11 encode device that exposes captured textures to NVENC.

Member Function Documentation

convert()

int platf::dxgi::d3d_nvenc_encode_device_t::convert ( platf::img_t & img_base )

inlineoverridevirtual

Convert a captured D3D texture for NVENC encoding.

Parameters

img_base

D3D image supplied by the capture backend.

Returns

Conversion status.

Implements platf::encode_device_t.

init_device()

bool platf::dxgi::d3d_nvenc_encode_device_t::init_device ( std::shared_ptr< platf::display_t > display, adapter_t::pointer adapter_p, pix_fmt_e pix_fmt )

inline

Create D3D11 and NVENC resources for texture-based encoding.

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

True when the D3D11 device resources are initialized.

init_encoder()

bool platf::dxgi::d3d_nvenc_encode_device_t::init_encoder ( const ::video::config_t & client_config, const ::video::sunshine_colorspace_t & colorspace )

inlineoverride

Initialize the platform encoder for the client stream configuration.

Parameters

client_config	Client stream configuration negotiated for this session.
colorspace	Colorimetry information used for conversion or encoding.

Returns

True when the NVENC encoder initializes for the client configuration.
