HTML5 video tag don't play video in ionic 3 ios version

I have an ionic 3 project, on a page I want to display video with html 5 video tag.
<video controls preload="metadata" webkit-playsinline="webkit-playsinline" class="videoPlayer"> <source [src]="article.videoMP4Url | safe" type="video/mp4"/> <source [src]="article.videoOgvUrl | safe" type="video/ogg"/> <source [src]="article.videoWebmUrl | safe" type="video/webm"/> </video>
src I have from back-end. It perfectly work in android version, but don’t work in ios version.
