I have tried a few different variations but this is what i have currently. This code works on everything pc and android but NOT IOS. I also used IFRAMEs originally but had the same effect but it wouldn't let me embed the mov. file

<div class="container bg-white">
<div class="row">
<div class="col-xl-8 "    style ="padding-top: 25px">

<div class="embed-responsive embed-responsive-16by9  bg-secondary">

<embed 

src="video/IMG_6921_webm.webm" allowfullscreen   
src="video/IMG_6921_avi.avi"  allowfullscreen 
src="video/IMG_6921_mp4.mp4" allowfullscreen
src="video/IMG_6921_mov.mov" width="32" height="32">

</embed>

</div>
  
</div>

字符串
我试过使用Iframes，但效果一样。这些视频在Chrome、Opera、FireFox、Edge、Android和Kindle上都能正常播放，但在iOS（苹果产品）上就不行了。“
