How to autoplay HTML5 mp4 video on Android?

Question

I had developed a mobile page by asp.net to play mp4 video.

I know iOS had disabled the autoplay function to minimize user bandwidth, so how can i autoplay HTML5 mp

Answer 1

I simplified the Javascript to trigger the video to start.

 var bg = document.getElementById ("bg"); 
 function playbg() {
   bg.play(); 
 }

<video id="bg" style="min-width:100%; min-height:100%;"  playsinline autoplay loop muted onload="playbg(); "><source src="Files/snow.mp4" type="video/mp4"></video>
</td></tr>
</table>

*"Files/snow.mp4" is just sample url

Answer 2

Android actually has an API for this! The method is setMediaPlaybackRequiresUserGesture(). I found it after a lot of digging into video autoplay and a lot of attempted hacks from SO. Here's an example from blair vanderhoof:

package com.example.myProject;

import android.os.Bundle;
import org.apache.cordova.*;
import android.webkit.WebSettings;

public class myProject extends CordovaActivity 
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        super.init();
        // Set by <content src="index.html" /> in config.xml
        super.loadUrl(Config.getStartUrl());
        //super.loadUrl("file:///android_asset/www/index.html");

        WebSettings ws = super.appView.getSettings();
        ws.setMediaPlaybackRequiresUserGesture(false);
    }
}

don't use "mute" alone, use [muted]="true" for example following code:

<video id="videoPlayer" [muted]="true" autoplay playsinline loop style="width:100%; height: 100%;">
<source type="video/mp4" src="assets/Video/Home.mp4">
<source type="video/webm" src="assets/Video/Home.webm">
</video>

I test in more Android and ios
