转换代码：

public static void aviconvertmp4(File source, File target){
    AudioAttributes audio = new AudioAttributes();
    audio.setCodec("libmp3lame"); //音频编码格式
    audio.setBitRate(new Integer(64000));
    audio.setChannels(new Integer(1));
    audio.setSamplingRate(new Integer(22050));
    VideoAttributes video = new VideoAttributes();
    video.setCodec("libx264");//视频编码格式
    video.setBitRate(new Integer(180000));
    video.setFrameRate(new Integer(1));
    EncodingAttributes attrs = new EncodingAttributes();
    attrs.setFormat("mp4");
    attrs.setAudioAttributes(audio);
    attrs.setVideoAttributes(video);
    Encoder encoder = new Encoder();
    MultimediaObject multimediaObject = new MultimediaObject(source);
    try {
        encoder.encode(multimediaObject, target, attrs);//转换开始。。。
    } catch (EncoderException e) {
        e.printStackTrace();
    }
}
