I am using a UIWebView in a Tab Bar application and I am having a <video> tag for some m4v clips. I have the desired behavior so far, however when the device goes from portrait to landscape, the video (and the controllers) remain as before. I am not 100% sure, but I suspect that the UITabBarController is "locking" the orientation change...
I am reading a document about HTML5. A few lines down from where I linked, a sample DOM tree is displayed for the sample HTML code given. Why is there no text node directly before the <head> element? Why is there no text node between the DOCTYPE and <html> nodes? Error or feature? ...

On other browsers it will render properly, like on the iPhone it will bring up the e-mail keyboard layout. I’d like to use this in a project but my input fields are <asp:TextBox> controls. How can I us...

I am wondering how I might set vim to color the new html5 elements (ie "canvas" and "video") as it does with the existing "script", "body" elements (or reserved words in other languages like python's "def") etc. Current version is from MacPorts typically used in a terminal emulator. ...

According to this Mozilla article on Ogg media, media works more seamlessly in the browser with an X-Content-Duration header, giving the length in seconds of the piece. Assuming that I have that length stored somewhere (certainly in a database, perhaps also in the filename itself (video-file-name.XXX.ogv, where XXX is the time in second...
Hi, I'm trying to pull together the javascript to seek through video by individual frames using HTML5. I had a few questions: 1) When you change the video.currentTime property, does this automatically re-render the video at the new time position.

However in the Webkit browsers (Safari and Chrome) the poster is dumped in favor of the first frame from the video as soon as the video metadata is fetched.

For the life of me I can figure out how to do a simple fast forward and rewind on the iPhone for an audio player using HTML5. All the Apple documentation says that the playbackRate should be used for this. I have watched the WWDC 2009 and 2010 sessions on this and downloaded all the example source code I can find but I still can't figure...
