我正在使用VideoJs 4.2播放器。
在iOS设备的Safari浏览器中打开videojs播放器时，默认情况下会使用本机控件。 当我暂停播放器时，我在视频上显示叠加按钮（链接到其他页面）。但是如果我在iOS上点击按钮，则无法触发。在桌面浏览器中运行良好。
如果我将nativeControlsForTouch设置为false，则会显示自定义控件。在这里，叠加按钮和自定义控件是可以工作的，但会很慢，我无法在视频上滚动，并且不如本机控件平滑。
请给我建议
- 如果我使用原生控件，则必须使叠加按钮正常工作
- 如果我使用自定义控件，则视频播放器将与本机控件相比更加流畅
这是我的代码：
videojs("ex_video",{"controls":true, "preload":"metadata","width":"auto", "height":"auto",
"poster":"/images/test.png"},function(){
var current_player=this;
current_player.imageOverlay({
opacity: 0.5,
height: '100%',
width: '50%'
});
current_player.on("pause", function(){
current_player.bigPlayButton.show();
});
current_player.on("play", function(){
current_player.bigPlayButton.hide();
});
});
覆盖按钮代码
