无法使用Xuggler对视频进行编码 [英] Can't encode video with Xuggler

问题描述

我正在尝试使用Xuggler创建简单的应用程序，Xuggler必须将图片序列编码为视频。
我已经安装了xuggler，如官方网站所述。
以下是代码示例（我在Xuggler维基站点上实际找到的）

I'm trying to create simple application with Xuggler, which has to encode sequence of pictures into video. I've installed xuggler, as described in official site. Here is example of code (which I've actually found on Xuggler wiki site)

import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.xuggle.mediatool.IMediaViewer;
import com.xuggle.mediatool.IMediaWriter;
import com.xuggle.mediatool.ToolFactory;
import com.xuggle.xuggler.ICodec;

import static com.xuggle.xuggler.Global.DEFAULT_TIME_UNIT;
import static java.util.concurrent.TimeUnit.SECONDS;
import static java.util.concurrent.TimeUnit.MILLISECONDS;


public class Test {

    private static final Logger log = LoggerFactory.getLogger(Test.class);
    {
        log.trace("<init>");
    }

    public static void main(String[] args) {

        final long duration = DEFAULT_TIME_UNIT.convert( 3, SECONDS );

        final int videoStreamIndex = 0;
        final int videoStreamId = 0;
        final long frameRate = DEFAULT_TIME_UNIT.convert(15, MILLISECONDS);
        final int width = 320;
        final int height = 200;

        long nextFrameTime = 0;

        final IMediaWriter writer = ToolFactory.makeWriter("/out.mov");

        writer.addVideoStream(videoStreamIndex, videoStreamId, 
                      width, height);

        while ( nextFrameTime < duration )
            {
                BufferedImage frame = new BufferedImage( 320, 200, BufferedImage.TYPE_INT_RGB );
                Graphics2D gr = (Graphics2D) frame.getGraphics();
                gr.setColor(Color.RED);
                gr.drawLine(0, 0, 200, 200);
                writer.encodeVideo(videoStreamIndex, frame, nextFrameTime, 
                       DEFAULT_TIME_UNIT);
                nextFrameTime += frameRate;
            }

        writer.close();

    }

}

启动后，我有异常：

Exception in thread "main" java.lang.UnsupportedOperationException: No converter "null" found.
    at com.xuggle.xuggler.video.ConverterFactory.createConverter(ConverterFactory.java:313)
    at com.xuggle.mediatool.MediaWriter.convertToPicture(MediaWriter.java:967)
    at com.xuggle.mediatool.MediaWriter.encodeVideo(MediaWriter.java:812)
    at Test.main(Test.java:48)

你能告诉我一些解决这个问题的方法吗？
谢谢

Could you advise me something to solve this problem? Thanks

推荐答案

Xuggler抱怨找不到BufferedImage的转换器。

Xuggler is complaining that it cannot find a converter for the BufferedImage.

使用 BufferedImage.TYPE_3BYTE_BGR 创建BufferedImage，而不是 BufferedImage.TYPE_INT_RGB

Create the BufferedImage with BufferedImage.TYPE_3BYTE_BGR instead of BufferedImage.TYPE_INT_RGB
