HTML5 - mp4 video does not play in IE9
问题 I have an mp4 video that I want to play in IE9 using HTML5 <video> tag. I added the MIME type to IIS 7 so if I browse http://localhost/video.mp4 it plays in both Chrome and IE9 but not in HTML5, Chrome plays the video in HTML though. Here's the code: <html> <body> <video src="video.mp4" width="400" height="300" preload controls> </video> </body> </html> Any ideas? Thanks UPDATE: Tried the same file in Firefox 5.0 and it didn't work either, only Chrome is able to play the mp4 video. 回答1: for
