构造函数。

<ParameterList title="参数">
<Parameter name="probeUplink">

是否探测上行网络。有些用户，如直播频道中的普通观众，不需要进行网络探测：

- 0: 探测
- 1: 不探测

</Parameter>
<Parameter name="probeDownlink">

是否探测下行网络：

- 0: 探测
- 1: 不探测

</Parameter>
<Parameter name="expectedUplinkBitrate">

用户期望的最高发送码率，单位为 bps，范围为 [100000, 5000000]。声网推荐参考 setVideoEncoderConfiguration 中的码率值设置该参数的值。

</Parameter>
<Parameter name="expectedDownlinkBitrate">

用户期望的最高接收码率，单位为 bps，范围为 [100000, 5000000]。
