How do I play video immediately on chrome ?

in other browsers, videos can be played directly when the layout is loaded. why can't chrome do it?

Most browsers are moving to an approach that blocks autoplay in order to avoid annoying users with unexpected audio playback. The playback can only be started in a click or touch event. I think Chrome did this first but you can expect all other browsers to follow.

so, what should I do so that the video can be played? I put one button to start playing the video but the video doesn't appear too. Firefox and Safari can do it well, even though Safari can't play it automatically. is it a codex video problem? or maybe the built-in flash player problem ?

now, i have turned off autoplay on the video and put a single button. When i clicked the button, the video started and then stopped. i don't know wheter it was buffering or lagging. the video just stop and i don't know what's happened (google chrome only). is google chrome needs to download pepperflash to play video on construct 2 ?
