◆ GetFrame() [1/2]

std::shared_ptr<openshot::Frame> openshot::ObjectDetection::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.

◆ GetFrame() [2/2]

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

override

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

The frame object is passed into this method, and a frame_number is passed in which tells the effect which settings to use from its keyframes (starting at 1).

Returns: The modified openshot::Frame object

Parameters

frame	The frame object that needs the effect applied to it
frame_number	The frame number (starting at 1) of the effect on the timeline.
