## How to Develop<a name="en-us_topic_0000001051451869_section1196016315516"></a>

1.  Perform step 1 through step 4 described in development guidelines on photographing.
2.  Obtain the  **FrameConfig**  instance for audio recording.

    ```
    /* Obtain the surface from the recorder. */
    Surface *surface = recorder_->GetSurface(0);
    surface->SetWidthAndHeight(1920, 1080);
    surface->SetQueueSize(3);
    surface->SetSize(1024 * 1024);
    /* Add the surface to the FrameConfig instance. */
    FrameConfig *fc = new FrameConfig(FRAME_CONFIG_RECORD);
    fc->AddSurface(*surface);
    ```

3.  Start and stop video recording.

    ```
    stateCallback->camera_->TriggerLoopingCapture(*fc); // Start recording.
    stateCallback->camera_->StopLoopingCapture(); // Stop recording.
    ```
