有出现过阿里云视频点播播放视频的时候一卡一卡的吗？

补充说一下, 客户端用的是web html5播放

            var player = new Aliplayer({
                id: 'J_prismPlayer',
                width: '100%',
                height: '768px',
                autoplay: true,
                vid: '{{ videoId }}',
                playauth: '{{ auth }}',
                cover: '{{ cover }}',
                playsinline: true,
                controlBarVisibility: "hover",
                useH5Prism: true

            }, function (player) {
                document.getElementById("videoStatus").value = 1;
            });
