| jsonStr | String | 是       | jitter配置参数的jsonObject转成的String | {"videoJitterUpper":4000, "videoJitterLower": 2000 "audioJitterUpper": 3000, "audioJitterLower": 1000 } |
   
JSON参数说明：
jitter上限（单位：ms）：key：videoJitterUpper，value ；设置接收端jitter buffer 0\~5000
jitter下限（单位：ms）：key：videoJitterLower，value ；设置接收端jitter buffer 0\~5000
jitter上限（单位：ms）：key：audioJitterUpper，value ；设置接收端jitter buffer 0\~5000
jitter下限（单位：ms）：key：audioJitterLower，value ；设置接收端jitter buffer 0\~5000
#### 调用样例
```
// 1. 接口
CloudPhoneClient.Callback.AppCallback callback = new CloudPhoneClient.Callback.AppCallback() {
  public static int setJitterBuffer(String jsonConfig) {
    return CloudPhoneClientInternal.setJitterBuffer(jsonConfig);
  }
};
// 2. 调用
JSONObject jitterBuffer = new JSONObject();
...
CloudPhoneClient.setJitterBuffer(JitterConfig.toString());
```
