HTML5 <video> element on Android

According to:

http://developer.android.com/sdk/android-2.0-highlights.html

Android 2.0 should support the HTML5 video element. I haven't been able to get this to work using a Motorola Droid, and haven't been able to successfully view a video on any of the HTML5 video example pages out there. Since there currently isn't support for QuickTime or Flash, this is the only other thing I can think of for embedding mp4 video in a web page. Has anyone had any luck with this?


I've just done some experimentation with this, and from what I can tell you need three things:

  1. You must not use the type attribute when calling the video.
  2. You must manually call video.play()
  3. The video must be encoded to some quite strict parameters; using the iPhone setting on Handbrake with the 'Web Optimized' button checked usually does the trick.

Have a look at the demo on this page: http://broken-links.com/tests/video/

This works, AFAIK, in all video-enabled desktop browsers, iPhone and Android.

Here's the markup:

<video id="video" autobuffer height="240" width="360">
<source src="BigBuck.m4v">
<source src="BigBuck.webm" type="video/webm">
<source src="BigBuck.theora.ogv" type="video/ogg">
</video>

And I have this in the JS:

var video = document.getElementById('video');
video.addEventListener('click',function(){
  video.play();
},false);

I tested this on a Samsung Galaxy S and it works fine.


Roman's answer worked fine for me - or at least, it gave me what I was expecting. Opening the video in the phone's native application is exactly the same as what the iPhone does.

It's probably worth adjusting your viewpoint and expect video to be played fullscreen in its own application, and coding for that. It's frustrating that clicking the video isn't sufficient to get it playing in the same way as the iPhone does, but seeing as it only takes an onclick attribute to launch it, it's not the end of the world.

My advice, FWIW, is to use a poster image, and make it obvious that it will play the video. I'm working on a project at the moment that does precisely that, and the clients are happy with it - and also that they're getting the Android version of a web app for free, of course, because the contract was only for an iPhone web app.

Just for illustration, a working Android video tag is below. Nice and simple.

<video src="video/placeholder.m4v" poster="video/placeholder.jpg" onclick="this.play();"/>

Here I include how a friend of mine solved the problem of displaying videos in HTML in Nexus One:

I never was able to make the video play inline. Actually many people on the internet mention explicitly that inline video play in HTML is supported since Honeycomb, and we were fighting with Froyo and Gingerbread... Also for smaller phones I think that playing full screen is very natural - otherwise not so much is visible. So the goal was to make the video open in full screen. However, the proposed solutions in this thread did not work for us - clicking on the element triggered nothing. Furthermore the video controls were shown, but no poster was displayed so the user experience was even weirder. So what he did was the following:

Expose native code to the HTML to be callable via javascript:

JavaScriptInterface jsInterface = new JavaScriptInterface(this);
webView.getSettings().setJavaScriptEnabled(true);
webView.addJavascriptInterface(jsInterface, "JSInterface");

The code itself, had a function that called native activity to play the video:

public class JavaScriptInterface {
    private Activity activity;

    public JavaScriptInterface(Activity activiy) {
        this.activity = activiy;
    }

    public void startVideo(String videoAddress){
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(Uri.parse(videoAddress), "video/3gpp"); // The Mime type can actually be determined from the file
        activity.startActivity(intent);
    }
}

Then in the HTML itself he kept on failing make the video tag work playing the video. Thus, finally he decided to overwrite the onclick event of the video, making it do the actual play. This almost worked for him - except for no poster was displayed. Here comes the most weird part - he kept on receiving ERROR/AndroidRuntime(7391): java.lang.RuntimeException: Null or empty value for header "Host" every time he set the poster attribute of the tag. Finally he found the issue, which was very weird - it turned out that he had kept the source subtag in the video tag, but never used it. And weird enough exactly this was causing the problem. Now see his definition of the video section:

<video width="320" height="240" controls="controls" poster='poster.gif'  onclick="playVideo('file:///sdcard/test.3gp');" >
   Your browser does not support the video tag.
</video>

Of course you need to also add the definition of the javascript function in the head of the page:

<script>
  function playVideo(video){
    window.JSInterface.startVideo(video);
  }
</script>

I realize this is not purely HTML solution, but is the best we were able to do for Nexus One type of phone. All credits for this solution go to Dimitar Zlatkov Dimitrov.
