一、设置编码参数
对于IPC默认的编码参数可能并不是我们所想要的，这时候可以设置IPC设备的编码参数，通过SetVideoEncoderConfiguration来设置
二、获取编码参数实现
1、创建tcp socket，IP为192.168.100.123，端口：8099；
2、填写token="000",Name="VideoE_000"，编码格式Encoding = H264,视频分辨Resolution = 1280*720,帧率FrameRateLimit = 15,码流BitrateLimit = 1792，I帧间隔GovLength = 1,设备IP = 192.168.100.123,端口 Port = 8099；
3、通过ONVIF Device Test Tool工具SetVideoEncoderConfiguration数据:
4、发送(send)数据：
<?xml version="1.0" encoding="utf-8"?>
