Fix an issue where the video size was incorrectly retrieved from preview size

        const CameraParameters& params,

        int32_t width, int32_t height) {

    // The actual video size is the same as the preview size

    // if the camera hal does not support separate video and

    // preview output. In this case, we retrieve the video

    // size from preview.

    int32_t frameWidthActual = -1;

    int32_t frameHeightActual = -1;

    Vector<Size> sizes;

    params.getSupportedVideoSizes(sizes);

    if (sizes.size() == 0) {

        // video size is the same as preview size

        params.getPreviewSize(&frameWidthActual, &frameHeightActual);

    } else {

        // video size may not be the same as preview

        params.getVideoSize(&frameWidthActual, &frameHeightActual);

    }

    if (frameWidthActual < 0 || frameHeightActual < 0) {

        LOGE("Failed to retrieve video frame size (%dx%d)",

                frameWidthActual, frameHeightActual);
