Can I avoid the native fullscreen video player with HTML5 on iPhone or android?

Question

In iOS 10+

Apple enabled the attribute playsinline in all browsers on iOS 10, so this works seamlessly:

<video src="file.mp4" playsinline>

In iOS 8 and iOS 9

Short answer: use iphone-inline-video, it enables inline playback and syncs the audio.

Long answer: You can work around this issue by simulating the playback by skimming the video instead of actually .play()'ing it.

There's a property that enables/disables in line media playback in the iOS web browser (if you were writing a native app, it would be the allowsInlineMediaPlayback property of a UIWebView). By default on iPhone this is set to NO, but on iPad it's set to YES.

Fortunately for you, you can also adjust this behaviour in HTML as follows:

<video id="myVideo" width="280" height="140" webkit-playsinline>

...that should hopefully sort it out for you. I don't know if it will work on your Android devices. It's a webkit property, so it might. Worth a go, anyway.

Old answer (applicable till 2016)

Here's an Apple developer link that explicitly says that -

on iPhone and iPod touch, which are small screen devices, "Video is NOT presented within the Web Page"

Safari Device-Specific Considerations

Your options:

• The webkit-playsinline attribute works for HTML5 videos on iOS but only when you save the webpage to your home screen as a webapp - Not if opened a page in Safari
• For a native app with a WebView (or a hybrid app with HTML, CSS, JS) the UIWebView allows to play the video inline, but only if you set the allowsInlineMediaPlayback property for the UIWebView class to true

In iOS 10 beta 4.The right code in HTML5 is

<video src="file.mp4" webkit-playsinline="true" playsinline="true">

webkit-playsinline is for iOS < 10, and playsinline is for iOS >= 10

See details via https://webkit.org/blog/6784/new-video-policies-for-ios/

According to this page https://developer.apple.com/library/archive/documentation/AppleApplications/Reference/SafariHTMLRef/Articles/Attributes.html it is only available if (Enabled only in a UIWebView with the allowsInlineMediaPlayback property set to YES.) I understand in Mobile Safari this is YES on iPad and NO on iPhone and iPod Touch.

I don't know about android, but Safari on the iPhone or iPod touch will play all videos full screen because of the small screen size. On the iPad it will play the video on the page but allow the user to make it full screen.
