Struct FrameTimeWithRate

A struct that represents a time in a frame sequence.

Namespace: Unity.LiveCapture

Assembly: Unity.LiveCapture.dll

Syntax

public readonly struct FrameTimeWithRate

Remarks

A time specified relative to a frame sequence cannot be converted to other representations or generally compared unless the frame rate of the sequence is also known. This struct stores both pieces of data needed to fully represent the time.

Parameters

Type	Name	Description
FrameRate	frameRate	The frame rate to convert to.

Returns

Type	Description
FrameTimeWithRate	A new FrameTimeWithRate remapped to the the target frame rate, or default if frameRate is invalid.

ToSeconds()

Gets the time represented by this FrameTimeWithRate in seconds.

Declaration
