红5通过直播和Xuggle生成FLV

我使用Red5录制来自用户的实时流。我可以将流保存到磁盘,它生成一个FLV文件。

任何洞察力都将不胜感激。

下面是我的相关Red5(JAVA)代码:

public void record(IConnection conn, String streamName) 
{
  ClientBroadcastStream stream = (ClientBroadcastStream) getBroadcastStream(
  conn.getScope(), streamName);
  try {
        stream.saveAs(streamName, false);
  } catch (Exception e) {
        System.out.print(e.getMessage());
  }
}

public void encodeWithXuggler(IConnection conn, String streamName)
{
   String nm = "C:\\Program Files\\Red5\\webapps\\Red5Recorder\\streams\\"+
              streamName+".flv";
   File f = new File(nm);

   if (f.exists()) {

   IMediaReader reader = ToolFactory.makeReader(nm);

   reader.addListener(ToolFactory.makeWriter("output.mov", reader));

   while (reader.readPacket() == null);

   } else {
       System.out.print("NOT EXiST");
   }

}
