如何从Android中的图像数组创建视频（） _Android

【如何从Android中的图像数组创建视频（）】千磨万击还坚劲，任尔东西南北风。这篇文章主要讲述如何从Android中的图像数组创建视频？相关的知识，希望能为你提供帮助。
我想调用一个函数并从图像列表中构建一个视频，然后将其本地保存在设备上：

public void CreateAndSaveVideoFile(List< Bitmap> MyBitmapArray) { // .. }

试验：

在java/xuggle - encode array of images into a movie之后，答案中的链接是一个死链接
在How to encode images into a video file in Java through programming?之后，接受的答案中建议的库不支持android。
上面的下一个答案有针对Android用户的方法，但我不清楚该功能的输入和输出（他在哪里提供图像？他在哪里获得视频？） - 我留下了一个问题评论
上面的下一个答案提供了一个完整的类，但是要包含的所需库有一个损坏的文件（当我尝试从提供的链接下载它时） - 我留下了一个问题评论
在Java: How do I create a movie from an array of images?之后，顶部答案中建议的库使用了我不熟悉的命令，我甚至不知道如何使用它们。喜欢：

从当前目录中的所有JPEG文件创建MPEG-4文件：
mencoder mf://*.jpg -mf w=800:h=600:fps=25:type=jpg -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell -oac copy -o output.avi

我不知道如何在java / Android项目中使用上述内容。
任何人都可以帮助指导我或/并为我提供一个方法来完成我的任务吗？提前致谢。
答案您可以使用jcodec SequenceEncoder将图像序列转换为MP4文件。
示例代码：

import org.jcodec.api.awt.SequenceEncoder; ... SequenceEncoder enc = new SequenceEncoder(new File("filename")); // GOP size will be supported in 0.2 // enc.getEncoder().setKeyInterval(25); for(...) { BufferedImage image = ... // Obtain an image to encode enc.encodeImage(image); } enc.finish();

它是一个java库，所以很容易将它导入到Android项目中，你不必像ffmpeg那样使用NDK。
有关示例代码和下载，请参阅http://jcodec.org/。
另一答案使用JCodec

public static void main(String[] args) throws IOException { SequenceEncoder encoder = new SequenceEncoder(new File("video.mp4")); for (int i = 1; i < 100; i++) { BufferedImage bi = ImageIO.read(new File(String.format("img%08d.png", i))); encoder.encodeImage(bi); } encoder.finish(); }

现在要将Bitmap转换为BufferedImage，您可以使用此类：
