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。
