    <div id="imgOut"></div>
    <script>
       var cut = function (){
            var scale = 0.25;
            var video = document.getElementById("player_html5_api");
            var canvas = document.createElement("canvas");
            canvas.width = video.videoWidth * scale;
            canvas.height = video.videoHeight * scale;
            canvas.getContext('2d').drawImage(video, 0, 0, canvas.width, canvas.height);
            canvas.setAttribute("id", "canvas");
            document.getElementById("imgOut").append(canvas)
            console.log(canvas.toDataURL());
        }

    </script>
</body>

</html>

注：

① canvas.toDataURL()会报错

②实际项目中，需要上传图片接口，获取图片的url
