Detailed Description

Clip, specific description of audio and video files.

A clip is an entity that accommodates audio and video content. It is a description of video and audio files, and is divided into an audio clip (Audio Clip) and a video clip (Video Clip). It defines the common attributes and behaviors of different types of clips. That is, the derived audio clips and video clips can be modified for your demand. These modifications include trim in and out points, left or right volume channels, playback speed and so on. In the SDK framework, corresponding audio clips and video clips can be added to the track.

Warning: In the NvsClip class, all public APIs are used in the UI thread! ! !

Member Function Documentation

void com.meicam.sdk.NvsClip.changeSpeed ( double newSpeed )

inline

Changes the playback speed of the clip.

Parameters

newSpeed New playback speed.

Warning: This interface will cause the streaming engine state to jump to the engine stop state, refer to Engine Change Feature for details.

See also: getSpeed

void com.meicam.sdk.NvsClip.changeSpeed	(	double	newSpeed,
		boolean	keepAudioPitch
	)

Since: 1.15.1

long com.meicam.sdk.NvsClip.changeTrimInPoint	(	long	newTrimInPoint,
		boolean	affectSibling
	)

inline

Modifies the trim in point of the clip.

Parameters

newTrimInPoint	New trim in point (in microseconds).
affectSibling	Whether it affects other clips on the same track (true/false).

Returns: Returns the actual reachable trim in point (in microseconds). Note: The actual achievable trim in point is within [0,trimOut - 1].

Warning: This interface will cause the streaming engine state to jump to the engine stop state, please refer to Engine Change Feature for details.

long com.meicam.sdk.NvsClip.changeTrimOutPoint	(	long	newTrimOutPoint,
		boolean	affectSibling
	)

inline

Modifies the trim out point of the clip.

Parameters

newTrimOutPoint	New trim out point (in microseconds).
affectSibling	Whether it affects other clips on the same track (true/false).

Returns: Returns the actual reachable trim out point (in microseconds). Note: The actual achievable trim out point is within [trimIn + 1, clipDuration] and clipDuration is the clip duration.

Warning: This interface will cause the streaming engine state to jump to the engine stop state, refer to Engine Change Feature for details.
