Detailed Description

video track,the collection of video clips.

A video track is an entity that holds video clips, and users can add, insert, and delete multiple video clips. The video track continues to expand as the clip increases, and video transitions can be inserted between clips. When adding a package transition, users need to install it and get the packageID returned as the handle of the transition. For built-in transition, their names are regarded as handle. Note: The index of the video clip starts from 0.

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

◆ addClip() [1/2]

NvsVideoClip com.meicam.sdk.NvsVideoTrack.addClip	(	String	filePath,
		long	inPoint
	)

inline

add clip.

Parameters

filePath Clip file path. For the clip's path in Android, there are two ways:

a. Creates an assets folder in the local program path, usually in the same directory as the res folder. The corresponding audio and video resources can be placed inside, the path form: "assets: /video20170406101714.mp4".

b. Imports the audio and video resources in the mobile phone through the absolute path, the path form: "/storage/Media/DCIM/IMG_0646.MP4".

Parameters

inPoint The in point of the clip on the timeline (in microseconds) For more information of the in and out points of a clip on the timeline, please refer to the section trimIn and trimOut.

Returns: Return the added video clip object

◆ addClip() [2/2]

NvsVideoClip com.meicam.sdk.NvsVideoTrack.addClip	(	String	filePath,
		long	inPoint,
		long	trimIn,
		long	trimOut
	)

inline

Adds a clip of the specified length.

Parameters

filePath	Clip path. For clip path types, please refer to the parameter filePath of addClip().
inPoint	The in point of the clip on the timeline (in microseconds).
trimIn	clip trim in point (in microseconds).
trimOut	clip trim out point (in microseconds).

Returns: Returns the added video clip object. When users use addClip() to add clips, the clip to be added will split the current clip at the specified in point on the timeline. In the specified in point, the clips contained in the position corresponding to the length of the clip to be added on the track will be deleted. Then the clips to be added can be added. If there is a gap in the corresponding position, it will be covered directly. examples are as follows:

As shown above, there are three video clips C1, C2, C3 on the track, and a clip C4 is to be added. The arrow on the C4 clip points to the trim in amd out points of the clip. The arrow on the track refers to the in-point of the clip on the timeline. After clipping, the corresponding clip is added to the track. The code is implemented as follows: NvsVideoTrack videoTrack; //videoTrack Omits creation here. videoTrack.addClip(filepath,inPoint,trimIn,trimOut);//Filepath is the path of the clip C4, and inPoint is the value of the position indicated by the arrow on the track in the figure, and trimIn and trimOut are the values at the position indicated by the arrow on the C4 clip of the above figure.

When added, the results are as follows:

Warning: This interface will cause the streaming engine state to jump to the engine stop state. For details, please refer to Engine Change.; Parameters need to meet (0 <= trimIn < trimOut). If trimOut is bigger than the file original duration, it will be played in the last frame

◆ setBuiltinTransition()

NvsVideoTransition com.meicam.sdk.NvsVideoTrack.setBuiltinTransition	(	int	srcClipIndex,

inline

Sets built-in transitions.

Parameters

srcClipIndex	Source video clip index.
transitionName	The name of the transition. To get the video transition name, please refer to getAllBuiltinVideoTransitionNames() or built-in effect name list. Note: If the transition name is set to a null string, the original transition will be deleted.

Returns: Returns the video transition object. If the transitionName is set to a null string (namely, to delete the original transition), return null.

For instance: There are four video clips on the track in the below figure, which are C1, C2, C3, and C4, respectively, where clip C1, C2, and C3 are adjacent, and there is a gap between clip C3 and C4. If a transition is set between C1 and C2, it becomes:

               NvsVideoTrack m_videoTrack;//m_videoTrack omitted creation
               int clipCount = m_videoTrack.getClipCount();
               NvsVideoTransition m_videoTransition;
               m_videoTransition = m_videoTrack.setBuiltinTransition(0,transitionName) //srcClipIndex takes the range of (1, clipCount-1), and transitionName is the name of the transition to be set.

If a transition is added between C2 and C3, the index is 1. The transition can only be set between two adjacent clips. Since there is a gap between the C3 and C4 clip in the above figure, it is not possible to add a transition between the two clips.
