2.4.1版本之前
/**
* @param context 上下文
* @param srcVideoPath 输入视频路径

@Override
public void onStart() {
}
@Override
public void onFinish() {
}
@Override
public void onFail(int errorCode, String msg) {
}
});2.4.1版本之后
/**

@Override
public void onStart() {
}
@Override
public void onFinish() {
}
@Override
public void onFail(int errorCode, String msg) {
}
});4.6 视频变速
/**

* @param destPath 输出视频路径
* @param speed 变速倍率 取值0.5f~2.0f
* @param listener 处理过程回调
*/

@Override
public void onStart() {
}
@Override
public void onFinish() {
}
@Override
public void onFail(int errorCode, String msg) {
}
});
4.7 添加音乐、贴纸和气泡文字
添加音乐时要先通过MusicSet类进行音乐设置。
MusicSet musicSet = null;
if (isAddMusic) {
musicSet = new MusicSet();
int startMusicPos = startCutMusicPosition / 1000;
//设置音乐路径
musicSet.setMusicPath(bacMusicPath);
//设置音乐开始的位置，单位：秒
musicSet.setStartMusicPos(startMusicPos);
//原声大小 0.0~1.0f
musicSet.setOriginVolume(originVolume);
//音乐大小 0.0~1.0f
musicSet.setMusicVolume(musicVolume);
}
添加贴纸和气泡文字时，通过StickerSet进行贴纸和气泡文字设置。
List<StickerSet> stickerSets = new ArrayList<>();
StickerSet stickerSet = new StickerSet();
//设置贴纸和气泡文字开始显示的时间，单位：秒
stickerSet.setStartShowTime(sticker.getStartShowTime());
//设置贴纸和气泡文字结束显示的时间，单位：秒
stickerSet.setEndShowTime(sticker.getEndShowTime());
//设置X轴偏移位置
stickerSet.setxOffSet(xOffSet);
//设置y轴偏移位置
stickerSet.setyOffSet(yOffSet);
//设置贴纸和气泡文字路径
stickerSet.setStickerPath(stickerPath);
stickerSets.add(stickerSet);只添加音乐时，传入参数musicSet，stickerSets传入参数null。只添加贴纸和气泡文字时，传入参数stickerSets，musicSet传入参数null。同时添加音乐、贴纸和气泡文字时，传入参数stickerSets和musicSet。
/**
* @param context 上下文
* @param srcVideoPath 输入视频路径
* @param destPath 输出视频路径
* @param musicSet 音乐设置
* @param stickerSets 贴纸和气泡设置
* @param listener 处理监听器
*/
ShortVideoHelper.AddMusicAndSticker(context, srcVideoPath, destPath, musicSet, null, new HandleProcessListener() {
@Override
public void onStart() {
}
@Override
public void onFinish() {
}
@Override
public void onFail(int errorCode, String msg) {
}
});
4.8 为视频添加黑边合成新视频
/**
* @param context 上下文
* @param srcVideoPath 输入视频路径
* @param destPath 输出视频路径
* @param videoWidth 输入视频宽度
* @param videoHeight 输入视频高度
* @param destVideoWidth 输出视频宽度
* @param destVideoHeight 输出视频高度
* @param listener 处理监听器
*/
ShortVideoHelper.changeVideoSize(context, srcVideoPath, destPath, videoWidth, videoHeight, 720, 1280, new HandleProcessListener() {
@Override
public void onStart() {
}
@Override
public void onFinish() {
}
@Override
public void onFail(int errorCode, String msg) {
}
}); 4.9 图片合成视频
为图片设置展示时长。
//单位：毫秒
image.setImageTime(int time);为图片设置动画效果。
//animType=0:无动画效果，animType=1:放大 ，animType=2:缩小，animType=3:左滑，animType=4:右滑
image.setImageAnimType(int animType);设置转场效果。
//transitionType=0:无转场，transitionType=1：重叠，transitionType=2：闪黑，transitionType=3：闪白，transitionType=4：圆形
image.setTransitionType(int transitionType);设置转场时长。
//单位：毫秒
image.setTransitionTime(int time);生成预览视频。
/**
* @param context 上下文
* @param selectedImages 图片集合
*/
ImagesVideo imagesVideo = ImagesToVideoHelper.makeImagesVideo(activity, selectedImages);//播放预览视频
SurfaceImagesVideoRenderer surfaceImagesVideoRenderer = new TextureImagesVideoRender(ivTextureView);
ImagesVideoPlayer imagesVideoPlayer = new ImagesVideoPlayer(activity);
imagesVideoPlayer.setImagesVideoRenderer(surfaceImagesVideoRenderer);
imagesVideoPlayer.setImagesVideoListener(this);
imagesVideoPlayer.setLoop(true);
imagesVideoPlayer.setDataSource(imagesVideo);
imagesVideoPlayer.prepare();
imagesVideoPlayer.setOnPreparedListener(new ImagesVideoPlayer.OnPreparedListener() {
@Override
public void onPreparing(ImagesVideoPlayer imagesPlayer, float progress) {
}
@Override
public void onPrepared(ImagesVideoPlayer imagesPlayer, int prepared, int total) {
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
isPrepared = true;
imagesVideoPlayer.start();
}
});
}
@Override
public void onError(ImagesVideoPlayer imagesPlayer) {
}
});
控制播放器暂停、播放、滑动。
//播放
imagesVideoPlayer.start();
//暂停
imagesVideoPlayer.pause();
//滑动
imagesVideoPlayer.seekTo(int pos);播放界面销毁时，销毁播放器。
@Override
protected void onDestroy() {
super.onDestroy();
if (imagesVideoPlayer != null) {
imagesVideoPlayer.destroy();
}
}将图片合成视频。
ImagesVideoMaker imagesVideoMaker = new ImagesVideoMaker(activity);
/**
* @param width 视频宽度
* @param height 视频高度
* @param frameRate 帧率
* @param bitRate 比特率
* @param iFrameInterval 关键帧间隔
* @param outputPath 输出路径
*/
imagesVideoMaker.setConfig(int width, int height, int frameRate, int bitRate, int iFrameInterval, String outputPath);
ImagesVideo newImagesVideo = ImagesToVideoHelper.makeImagesVideo(activity, selectedImages);
SurfaceImagesVideoRenderer videoRenderer = new SurfaceImagesVideoRenderer(surfaceImagesVideoRenderer);
videoRenderer.setImagesVideo(newImagesVideo);
imagesVideoMaker.setDataSource(videoRenderer);
imagesVideoMaker.startMake(new ImagesVideoMaker.OnMakeListener() {
@Override
public void onMakeFinish(boolean success) {
}
@Override
public void onMakeProgress(int makedDuration, int totalDuration) {
}
});
