How to set autoplay for iframeHtml ?

[BlackProgTime]

I use ngx-embed-video/dist for my video section on web page. I try to set autoplay like it is write in documentation but it don't work for me. Who can help me with fixing it ?
Here I set iframeHtml

`
"<div class="videoPlayer" [innerHTML]="iframeHtml">"

loadVideo() {
if (this.validUrl.transform(this.video.url)) {
this.iframeHtml = this.embedService.embed(this.video.url, {
query: { autoplay: 1 }
});
}
}
`
