二. RTSP的常用命令与解释
       其中C是客户端，S是服务端。
2.1 OPTIONS
       C->S:       OPTION request //询问S有哪些方法可用
       S->C:       OPTION response //S回应信息中包括提供的所有可用方法
      使用举例：
客户端到服务端：

Java代码
OPTIONS rtsp://218.207.101.236:554/mobile/3/67A451E937422331 RTSP/1.0
Cseq: 1

OPTIONS rtsp://218.207.101.236:554/mobile/3/67A451E937422331 RTSP/1.0
Cseq: 1 服务端对OPTIONS的回应：

Java代码
RTSP/1.0 200 OK
Server: PVSS/1.4.8 (Build/20090111; Platform/Win32; Release/StarValley; )
Cseq: 1
Public: DESCRIBE, SETUP, TEARDOWN, PLAY, PAUSE, OPTIONS, ANNOUNCE, RECORD

RTSP/1.0 200 OK
Server: PVSS/1.4.8 (Build/20090111; Platform/Win32; Release/StarValley; )
Cseq: 1
Public: DESCRIBE, SETUP, TEARDOWN, PLAY, PAUSE, OPTIONS, ANNOUNCE, RECORD

2.2 DESCRIBE

      C->S:      DESCRIBE request //要求得到S提供的媒体初始化描述信息
      S->C:      DESCRIBE response //S回应媒体初始化描述信息，主要是sdp

     使用举例：

3.1 接口IEvent.java

接口IEvent.java的代码如下：

package com.amigo.rtsp;   
  
import java.io.IOException;   
import java.nio.channels.SelectionKey;   
  
/** *//**  
* IEvent.java 网络事件处理器，当Selector可以进行操作时，调用这个接口中的方法.  
* 2007-3-22 下午03:35:51  
* @author sycheng  
* @version 1.0  
*/  
public interface IEvent {   
    /** *//**  
    * 当channel得到connect事件时调用这个方法.  
    * @param key  
    * @throws IOException  
    */  
    void connect(SelectionKey key) throws IOException;   
  
    /** *//**  
    * 当channel可读时调用这个方法.  
    * @param key  
    * @throws IOException  
    */  
    void read(SelectionKey key) throws IOException;   
  
    /** *//**  
    * 当channel可写时调用这个方法.  
    * @throws IOException  
    */  
    void write() throws IOException;   
  
    /** *//**  
    * 当channel发生错误时调用.  
    * @param e  
    */  
    void error(Exception e);   
}
