Member Typedef Documentation

◆ Parent

using av::VideoEncoderContext::Parent = VideoCodecContext<VideoEncoderContext, Direction::Encoding>

Constructor & Destructor Documentation

◆ VideoEncoderContext() [1/2]

av::VideoEncoderContext::VideoEncoderContext ( )

default

◆ VideoEncoderContext() [2/2]

av::VideoEncoderContext::VideoEncoderContext ( VideoEncoderContext && other )

Member Function Documentation

◆ encode() [1/2]

Packet av::VideoEncoderContext::encode	(	const VideoFrame &	inFrame,
		OptionalErrorCode	ec = `throws()`
	)

encodeVideo - encode video frame

Note: Some encoders need some amount of frames before beginning encoding, so it is normal, that for some amount of frames returns empty packets.

Parameters

	inFrame	frame to encode
[in,out]	ec	this represents the error status on exit, if this is pre-initialized to av::throws the function will throw on error instead

Returns

◆ encode() [2/2]

Packet av::VideoEncoderContext::encode ( OptionalErrorCode ec = throws() )

encodeVideo - Flush encoder

Stop flushing when returns empty packets

Parameters

[in,out] ec this represents the error status on exit, if this is pre-initialized to av::throws the function will throw on error instead

Returns

◆ operator=()

VideoEncoderContext & av::VideoEncoderContext::operator= ( VideoEncoderContext && other )
