Gatsby 中怎么加载使用视频文件？

import * as React from 'react'
import dog from '../assets/dog.mp4'

const VideoShow = () => {

    return (
        <div>
            <video width="70%" controls>
                <source src={dog} type="video/mp4" />
            </video>

            <video width="70%" controls>
                <source src="https://api.learn-anything.cn/uploads/dog_14be0bfb5a.mp4" type="video/mp4" />
            </video>
        </div>
    )
}

export default VideoShow;
