Overview

时间切片信息

`– initWithTimeRange:`

根据 TuSDKMediaTimeRange 初始化 TuSDKMediaTimelineSlice

- (instancetype)initWithTimeRange:(TuSDKMediaTimeRange *)timeRange

Parameters

`timeRange`	时间区间

Return Value

TuSDKMediaTimelineSlice

Availability

v3.0

Declared In

`– initWithCMTimeRange:`

根据开始时间和结束时间初始化时间范围。当开始时间大于结束时间时为倒序读取模式

- (instancetype)initWithCMTimeRange:(CMTimeRange)timeRange

Parameters

`timeRange`	时间区间

Return Value

TuSDKMediaTimeRange

Availability

v3.0

Declared In

`– initWithStart:end:`

根据开始时间和结束时间初始化时间范围。当开始时间大于结束时间时为倒序读取模式

- (instancetype)initWithStart:(CMTime)start end:(CMTime)end

Parameters

`start`	开始时间
`end`	结束时间

Return Value

TuSDKMediaTimeRange
