Member Function Documentation

◆ GetFrame() [1/2]

std::shared_ptr<openshot::Frame> openshot::Whisperization::GetFrame ( int64_t frame_number )

inlineoverridevirtual

This method is required for all derived classes of ClipBase, and returns a new openshot::Frame object. All Clip keyframes and effects are resolved into pixels.

Returns: A new openshot::Frame object

Parameters

frame_number The frame number (starting at 1) of the clip or effect on the timeline.

Implements openshot::ClipBase.

Definition at line 60 of file Whisperization.h.

◆ GetFrame() [2/2]

std::shared_ptr< openshot::Frame > Whisperization::GetFrame	(	std::shared_ptr< openshot::Frame >	frame,
		int64_t	frame_number
	)

overridevirtual

This method is required for all derived classes of ClipBase, and returns a modified openshot::Frame object.

The frame object is passed into this method and used as a starting point / background (pixels). All Clip keyframes and effects are resolved into pixels.

Returns: The modified openshot::Frame object

Parameters

frame	This is ignored on Clip, due to caching optimizations. This frame instance is clobbered with the source frame.
frame_number	The frame number (starting at 1) of the clip or effect on the timeline.

Implements openshot::ClipBase.

Definition at line 49 of file Whisperization.cpp.
