Detailed Description

FFmpeg software encode device used when no hardware frames are required.

Member Function Documentation

apply_colorspace()

void video::avcodec_software_encode_device_t::apply_colorspace ( )

inlineoverridevirtual

Apply the configured colorspace metadata to the active frame.

Reimplemented from platf::avcodec_encode_device_t.

convert()

int video::avcodec_software_encode_device_t::convert ( platf::img_t & img )

inlineoverridevirtual

Accept a software frame without additional hardware conversion.

Parameters

img	Image or frame object to read from or populate.

Returns

Conversion status.

Reimplemented from platf::avcodec_encode_device_t.

init()

int video::avcodec_software_encode_device_t::init ( int in_width, int in_height, AVFrame * frame, AVPixelFormat format, bool hardware )

inline

Initialize FFmpeg software encoding for the requested codec.

Parameters

in_width	In width.
in_height	In height.
frame	Video or graphics frame being processed.
format	Pixel, audio, or protocol format being converted.
hardware	Whether the frame is backed by hardware resources.

Returns

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

prefill()

void video::avcodec_software_encode_device_t::prefill ( )

inline

When preserving aspect ratio, ensure that padding is black

set_frame()

int video::avcodec_software_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.
