Detailed Description

D3D11 encode device that exposes captured textures to FFmpeg AVCodec.

Member Function Documentation

apply_colorspace()

void platf::dxgi::d3d_avcodec_encode_device_t::apply_colorspace ( )

inlineoverridevirtual

Apply the configured colorspace metadata to the active frame.

Reimplemented from platf::avcodec_encode_device_t.

convert()

int platf::dxgi::d3d_avcodec_encode_device_t::convert ( platf::img_t & img_base )

inlineoverridevirtual

Convert a captured D3D texture for FFmpeg AVCodec encoding.

Parameters

img_base

D3D image supplied by the capture backend.

Returns

Conversion status.

Reimplemented from platf::avcodec_encode_device_t.

init()

int platf::dxgi::d3d_avcodec_encode_device_t::init ( std::shared_ptr< platf::display_t > display, adapter_t::pointer adapter_p, pix_fmt_e pix_fmt )

inline

Initialize the D3D11 AVCodec encode device.

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_hwframes()

void platf::dxgi::d3d_avcodec_encode_device_t::init_hwframes ( AVHWFramesContext * frames )

inlineoverridevirtual

Configure FFmpeg hardware frames for D3D11 encoder input textures.

Parameters

frames

FFmpeg hardware frames context to initialize.

Reimplemented from platf::avcodec_encode_device_t.

prepare_to_derive_context()

int platf::dxgi::d3d_avcodec_encode_device_t::prepare_to_derive_context ( int hw_device_type )

inlineoverridevirtual

Prepare the D3D device before FFmpeg derives a child hardware context.

Parameters

hw_device_type

FFmpeg hardware device type requested for context derivation.

Returns

0 when context derivation may continue; nonzero to abort.

Reimplemented from platf::avcodec_encode_device_t.

set_frame()

int platf::dxgi::d3d_avcodec_encode_device_t::set_frame ( AVFrame * frame, AVBufferRef * hw_frames_ctx )

inlineoverridevirtual

Attach frame resources used by the next conversion or encode operation.

Parameters

frame	Video or graphics frame being processed.
hw_frames_ctx	FFmpeg hardware frames context associated with the frame.

Returns

Status from updating frame.

Reimplemented from platf::avcodec_encode_device_t.
