Java RTP如何解决数据包只有1480字节大小的限制

Question

发送端代码：
public static void openSession() {
InitSession test = new InitSession();
byte[] data = new byte[1500];
System.out.println("Send Length:"+data.length);

    long timeStarted = System.currentTimeMillis();
    int i = 0;
    while(i<3){
        test.rtpSession.sendData(data);
        i++;
    }

    long timeStop = System.currentTimeMillis();
    System.out.println("发送用时："+(timeStop-timeStarted));
}

错误：
RtpPkt.setPayload: Cannot carry more than 1480 bytes for now.

RtpPkt() failed, check with checkPkt()
Exception in thread "main" java.lang.NullPointerException
