关于Java视频压缩的问题

我用的是视频转码方式进行压缩
AudioAttributes audio = new AudioAttributes();
audio.setCodec(“libmp3lame”);
audio.setBitRate(new Integer(100000));
audio.setChannels(new Integer(1));
audio.setSamplingRate(new Integer(22050));
// 视频设置
VideoAttributes video = new VideoAttributes();
video.setCodec(“mpeg4”); // 视频编码格式mpeg4
video.setBitRate(new Integer(600000));
video.setFrameRate(new Integer(15)); // 视频帧率15
EncodingAttributes attrs = new EncodingAttributes();
// 视频封装类型
attrs.setFormat(“mp4”);
attrs.setVideoAttributes(video);
Encoder encoder = new Encoder();
encoder.encode(source, target, attrs);
