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：

File source = new File("source.avi");
File target = new File("target.flv");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libmp3lame");
audio.setBitRate(new Integer(64000));
audio.setChannels(new Integer(1));
audio.setSamplingRate(new Integer(22050));
VideoAttributes video = new VideoAttributes();
video.setCodec("flv");
video.setBitRate(new Integer(160000));
video.setFrameRate(new Integer(15));
video.setSize(new VideoSize(400, 300));
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("flv");
attrs.setAudioAttributes(audio);
attrs.setVideoAttributes(video);
Encoder encoder = new Encoder();
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。
