I have created a minimal PhoneGap app that has just this in the index.html:
<!-- ... -->
<body>
<video src="test.m4v" autoplay onerror="alert('Error')"></video>
</body>
In the PhoneGap.plist I have set MediaPlaybackRequiresUserAction to NO.
Yet I still cannot get the video to autoplay when the page loads. I have tried different ways of scripting it but to no avail.
Does anybody have a clue what I'm doing wrong?
Solved it. Turned out to be a bug in PhoneGap 1.3 which was fixed in version 1.4 released yesterday(!).
From the release notes:
Fixed CB-42 – MediaPlaybackRequiresUserAction can now be set to NO
AutoPlay attribute work in ios :
<video src="test.m4v" autoplay="autoplay"></video>
Given this line autoplay function
"autoplay" attribute will not work in iOS so you need to use JavaScript to get it to play.
Here is some sample code:
var video = document.getElementById('someVideoId');
video.play();
