我试图使用调用ffmpeg的JAVE将*.mov文件转码为*.mp4文件.输入文件和输出文件都是InputStream和OutputStream形式.这意味着我需要将InputStream和OutputStream作为-f和-y parematers传递给ffmpeg.我怎么做 ？

    //Read a movfile.mov converted into a FileInputStream  
    InputStream fileInputStream = getFileInputStream();  
    OutputStream fileOutputStream = new FileOutputStrea(outputMP4File) //Output        
    Process p = Runtime.exec("ffmpeg -i - -y -");  
    InputStream pInStrm = p.getInputStream();  
    OutputStream pOutStrm = p.getOutputStream();  
    int vin = 0, vout = 0;   

    Thread read = new Thread() {  
         byte[] buff = new byte[4096];  
          void run() {   
            while ((vin=fileInputStream.read(buf))!=-1) {   
                 pOutStrm.write(buf, 0, vin);   
            }   
         }   
      }; read.start();

    Thread write = new Thread() {  
        byte[] buff = new byte[4096];  
        void run() …
