Android.Xuggler在视频文件错误中添加音频

Question

我使用xuggler将音频和视频文件组合在一起。它显示了com.xuggler.mediaTool.ToolFactory NoClassDefFound错误异常的错误。如何解决它。 我已经添加了库。

这是我的代码

    IMediaWriter mWriter = ToolFactory.makeWriter(videoPath1 + "/merged.mp4");

    IContainer containerVideo = IContainer.make();
    IContainer containerAudio = IContainer.make();

    // check files are readable
    if (containerVideo.open(videoPath, IContainer.Type.READ, null) < 0)
        throw new IllegalArgumentException("Cant find " + videoPath);
    if (containerAudio.open(audioPath, IContainer.Type.READ, null) < 0)
        throw new IllegalArgumentException("Cant find " + audioPath);


    // read video file and create stream
    IStreamCoder coderVideo = containerVideo.getStream(0).getStreamCoder();
    if (coderVideo.open(null, null) < 0)
        throw new RuntimeException("Cant open video coder");
    IPacket packetvideo = IPacket.make();
    int width = coderVideo.getWidth();
    int height = coderVideo.getHeight();

    // read audio file and create stream
    IStreamCoder coderAudio = containerAudio.getStream(0).getStreamCoder();
    if (coderAudio.open(null, null) < 0)
        throw new RuntimeException("Cant open audio coder");
    IPacket packetaudio = IPacket.make();

    mWriter.addAudioStream(1, 0, coderAudio.getChannels(), coderAudio.getSampleRate());
    mWriter.addVideoStream(0, 0, width, height);

    while (containerVideo.readNextPacket(packetvideo) >= 0) {

        containerAudio.readNextPacket(packetaudio);

        // video packet
        IVideoPicture picture = IVideoPicture.make(coderVideo.getPixelType(), width, height);
        coderVideo.decodeVideo(picture, packetvideo, 0);
        if (picture.isComplete()) 
            mWriter.encodeVideo(0, picture);

        // audio packet 
        IAudioSamples samples = IAudioSamples.make(512, coderAudio.getChannels(), IAudioSamples.Format.FMT_S32);
        coderAudio.decodeAudio(samples, packetaudio, 0);
        if (samples.isComplete()) 
            mWriter.encodeAudio(1, samples);

    }

    coderAudio.close();
    coderVideo.close();
    containerAudio.close();
    containerVideo.close();
    mWriter.close();
