title: Setting runtime depth frame rate not successful
body: <p>I am trying to set the runtime depth frame rate but it is not successful. No error is returned but the depth frame rate keeps unchanged. I used the following code the set the depth frame rate.</p>
  
  <pre><code>TangoErrorType SetRuntimeDepthFrameRate(uint32_t frameRate)
  {
      TangoConfig runtimeConfig = TangoService_getConfig(TANGO_CONFIG_RUNTIME);
      if (runtimeConfig == nullptr) {
          LOGE("failed to get runtime config");
          return TANGO_ERROR;
      }
      TangoErrorType err = TangoConfig_setInt32(runtimeConfig, "config_runtime_depth_framerate", frameRate);
      if (err != TANGO_SUCCESS) {
          LOGE("failed to set runtime depth framerate to %d", frameRate);
          return err;
      }
      err = TangoService_setRuntimeConfig(runtimeConfig);
      if (err != TANGO_SUCCESS)
          LOGE("ailed to set runtime config");
  
      LOGI("the runtime depth framerate is set to %d", GetRuntimeDepthFrameRate());
  
      return err;
  }
  </code></pre>
  
  <p>I used the following code the query the runtime depth frame rate.</p>
  
  <pre><code>    int GetRuntimeDepthFrameRate() const {
      TangoConfig runtimeConfig = TangoService_getConfig(TANGO_CONFIG_RUNTIME);
      if (runtimeConfig == nullptr) {
          LOGE("failed to get runtime config");
          return -1;
      }
      int32_t depthFrameRate;
      TangoErrorType err = TangoConfig_getInt32(runtimeConfig, "config_runtime_depth_framerate", &amp;depthFrameRate);
      if (err != TANGO_SUCCESS) {
          LOGE("failed to get runtime depth framerate");
          return -1;
      }
      return depthFrameRate;
  }
  </code></pre>
  
  <p>The runtime depth frame rate is never changed, it is always 5. My program keeps calling the depth callbacks when I try to set the depth rate to 0 which means the rate is not set successfully.</p>
  
  <p>Is there anything wrong with what I am doing? 
  Thank you for any answers in advance.</p>
