Python 将有效负载类型为的scapy RTP数据包写入pcap时出错

当我用下面的代码在scapy中创建一个RTP数据包时，我得到一个错误：“TypeError:clone_with（）为关键字参数'payload'获取了多个值”

但移除有效载荷是可行的

rtp = { 
        "sequence": 1,
        "timestamp": 1,
        "marker": 1
    }

pkt = Ether()/IP()/UDP(sport=12345,dport=12346)/RTP(**rtp)
pktdump.write(pkt)

全部输出为

Traceback (most recent call last):
  File "test.py", line 23, in <module>
    pktdump.write(pkt)

回溯（最近一次呼叫最后一次）：
文件“test.py”，第23行，在
pktdump.write（pkt）
文件“/home/eisamar/devel/rtp2pcap/local/lib/python2.7/site packages/scapy/utils.py”，第657行，以书面形式
对于pkt中的p：
文件“/home/eisamar/devel/rtp2pcap/local/lib/python2.7/site packages/scapy/packet.py”，第661行，循环中
对于有效载荷中的有效载荷：

pkt=self.clone_与（有效负载=payl，**done2）
TypeError:clone_with（）为关键字参数“payload”获取了多个值

我做错了什么。。。？有解决办法吗？错误在第666行。。。嗯

谢谢

更改中建议的行通过将字段名称从

payload

更改为

payload\u type

解决了scapy的此问题：
