使用xuggler从一组图像创建视频 [英] Video Creation from a set of images with xuggler
本文介绍了使用xuggler从一组图像创建视频的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我发现了一些有趣的事情，但他们没有解决我的问题。我会解释一下。
我有一个视频，我用xuggler研究每一帧。当我得到所有的帧时，我用颜色算法编辑它们。此外，我将音频存储在mp3文件中。
现在我需要从所有框架创建一个视频，当然，这个视频应该具有相同的特性帧速e持续时间。之后，我必须合并音频。
我已经做了第一部分，但是我不知道如何创建一个具有相同特征的视频。我遵循这个代码：
http://www.javacodegeeks.com/2011/02/xuggler-tutorial-frames-capture-video.html
但它需要快照，它使用一个奇怪的循环：
for（int index = 0;索引< SECONDS_TO_RUN_FOR * FRAME_RATE;索引++）
我不知道如何设置正确的特征。这应该很容易，因为我知道有关视频的一切！大小，帧率和帧数。
我的代码：
public static void main（String [] args）throws IOException {
final IMediaWriter writer = ToolFactory.makeWriter（outputFilename）;
writer.addVideoStream（0，0，ICodec.ID.CODEC_ID_MPEG4，
720，304）;
long nextFrameTime = 0;
final long frameRate = 25/1000;
long startTime = System.nanoTime（）;
while（indexVideo< 1597）{
BufferedImage videoImage = null;
try {
videoImage = getVideoImage（）;
} catch（AWTException e1）{
// TODO自动生成的catch块
e1.printStackTrace（）;
}
writer.encodeVideo（0，videoImage，nextFrameTime，
TimeUnit.MILLISECONDS）;
nextFrameTime + = frameRate;
}
writer.close（）;
$ b private static BufferedImage getVideoImage（）throws IOException，AWTException {
File imgLoc = new File（D：/ Gianfranco / Sample /+ indexVideo + .PNG）;
BufferedImage img;
img = ImageIO.read（imgLoc）;
System.out.println（imgLoc.getName（））;
indexVideo ++;
return img;
}
任何人帮助我吗？

I have been looking for a solution everywhere! On this website and on others. I have found some interesting things, but they didn't solve my problem. I will explain it.
I have one video, I grad each frame of it with xuggler. When I get all the frames I edit all of them with a color algorithm. Also, I store the audio in an mp3 file.
Now I need to create a video from all the frames, this video, of course, should have the same characteristics as frame rate e duration. After that I have to merge the audio.
I have done the first part, but I don't know how to create a video with the same characteristics. I am following this code:
http://www.javacodegeeks.com/2011/02/xuggler-tutorial-frames-capture-video.html
Can't encode video with Xuggler
But it takes the snapshot and it uses a strange loop:
for (int index = 0; index < SECONDS_TO_RUN_FOR * FRAME_RATE; index++)
I can't figure out how to set the right characteristic. It should be easy because I know everything about the video! size, frame rate and number of frame.
My code:
public static void main(String[] args) throws IOException {
final IMediaWriter writer = ToolFactory.makeWriter(outputFilename);
writer.addVideoStream(0, 0, ICodec.ID.CODEC_ID_MPEG4,
720, 304);
long nextFrameTime = 0;
final long frameRate =25/1000;
long startTime = System.nanoTime();
while (indexVideo<1597) {
BufferedImage videoImage = null;
try {
videoImage = getVideoImage();
} catch (AWTException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
writer.encodeVideo(0, videoImage,nextFrameTime,
TimeUnit.MILLISECONDS);
nextFrameTime += frameRate;
}
writer.close();
}
private static BufferedImage getVideoImage() throws IOException, AWTException {
File imgLoc = new File("D:/Gianfranco/Sample/"+indexVideo+".png");
BufferedImage img;
img = ImageIO.read(imgLoc);
System.out.println(imgLoc.getName());
indexVideo++;
return img;
}
Ca anyone help me out?
