apply_colorspace()

void cuda::gl_cuda_vram_t::apply_colorspace ( )

inlineoverridevirtual

Configures shader parameters for the specified colorspace.

Reimplemented from platf::avcodec_encode_device_t.

convert()

int cuda::gl_cuda_vram_t::convert ( platf::img_t & img )

inlineoverridevirtual

Convert the captured image into the target CUDA frame.

Parameters

img	Captured screen image.

Returns

0 on success or -1 on failure.

Reimplemented from platf::avcodec_encode_device_t.

init()

int cuda::gl_cuda_vram_t::init ( int in_width, int in_height, int offset_x, int offset_y )

inline

Initialize the GL->CUDA encoding device.

Parameters

in_width	Width of captured frames.
in_height	Height of captured frames.
offset_x	Offset of content in captured frame.
offset_y	Offset of content in captured frame.

Returns

0 on success or -1 on failure.

set_frame()

int cuda::gl_cuda_vram_t::set_frame ( AVFrame * frame, AVBufferRef * hw_frames_ctx_buf )

inlineoverridevirtual

Initialize color conversion into target CUDA frame.

Parameters

frame	Destination CUDA frame to write into.
hw_frames_ctx_buf	FFmpeg hardware frame context.

Returns

0 on success or -1 on failure.

Reimplemented from platf::avcodec_encode_device_t.
