推荐一款基于Java的音视频处理开源项目--JAVE

JAVE（Java Audio Video Encoder），是一款将音频和视频在不同格式间进行转化的工具，是基于ffmpeg项目的Java封装。

JAVE，需要J2SE 1.4+、Windows 或 Linux 操作系统均可运行。

JAVE支持的编码和解码格式见下表：

JAVE的使用非常简便，将包jave-1.0.jar导入工程路径即可。下面给出一段将AVI转换成FLV的代码片段：

[java] view plaincopy

1. File source = new File("source.avi");  
2. File target = new File("target.flv");  
3. AudioAttributes audio = new AudioAttributes();  
4. audio.setCodec("libmp3lame");  
5. audio.setBitRate(new Integer(64000));  
6. audio.setChannels(new Integer(1));  
7. audio.setSamplingRate(new Integer(22050));  
8. VideoAttributes video = new VideoAttributes();  
9. video.setCodec("flv");  
10. video.setBitRate(new Integer(160000));  
11. video.setFrameRate(new Integer(15));  
12. video.setSize(new VideoSize(400, 300));  
13. EncodingAttributes attrs = new EncodingAttributes();  
14. attrs.setFormat("flv");  
15. attrs.setAudioAttributes(audio);  
16. attrs.setVideoAttributes(video);  
17. Encoder encoder = new Encoder();  
18. encoder.encode(source, target, attrs);  

细心看这段代码，不难找到其中可以设置压缩码率、分辨率、音频解码率等参数，非常的简便。
