问题 I have an inline video embedded in the home page of a cordova (phonegap) app for iOS. I have added the necessary allow setting to the config.xml <preference name="AllowInlineMediaPlayback" value="true" /> and the the video html looks like this <video webkit-playsinline poster="img/videoplaceholder.png" loop class="video" autoplay="autoplay"> <source src="media/homepage.iphone.mp4"/> </video> When the app first launches the video plays inline and works perfectly.

问题 I'm working on a more secure streaming method for our video player. Because each file requires special token authentication and also only allows each token to be loaded once, I'm running MP4 through a php container.

问题 While searching for difference between HTML4 and HTML5 I came across the point that : HTML5 brings a whole new dimension to web world.
