I've seen posts complaining that you cannot autoplay a video on mobile device.

But, this CAN be done. I've visited youtube website on android and iOS and video does indeed start to play without any user interaction. How can I mimic this behaviour?

EDIT: if you visit direct link, it does not work. If you first visit youtube.com and than click on some video, it works. No idea why.

  • Just don't do it! I sure don't want auto videos eating through my precious data allowances! – Ian Jun 30 '17 at 18:21
  • I understand your concerns. Mute gifs are 5x as big as mp4 video, yet nobody gives a damn. – sanjihan Jun 30 '17 at 18:26

You can use autoplay in video tag. like this:

<video width="320" height="240" controls autoplay>

For more information, you can learn from here: https://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_video_autoplay

For mobile, you should not do auto play because it will cost user's bandwidth(money). See this post for more detail: Can you autoplay HTML5 videos on the iPad?

  • @JackLuo, very correctly and well said, you should post this in your answer with a update. – divy3993 Jun 30 '17 at 17:58
