From reddit discussion ( https://www.reddit.com/r/firefox/comments/17ywbjj/comment/k9... ): > To clarify it more, it's simply this code in their polymer script link: > setTimeout(function() { c(); a.resolve(1) }, 5E3); > which doesn't do anything except making you wait 5s (5E3 = 5000ms = 5s).

That is not correct. The surrounding code gives some more context: h=document.createElement("video");l=new Blob([new Uint8Array([/* snip */])],{type:"video/webm"}); h.src=lc(Mia(l));h.ontimeupdate=function(){c();a.resolve(0)}; e.appendChild(h);h.classList.add("html5-main-video");setTimeout(function(){e.classList.add("ad-interrupting")},200); setTimeout(function(){c();a.resolve(1)},5E3); return m.return(a.promise)})}…

VLC somehow refuses to play it, but its nominal length can be verified with a short JS code like: v = document.createElement('video');
v.src = `data:video/webm;base64,`;
await new Promise(resolve => v.onloadedmetadata = resolve);
console.log(v.duration);
