Hello, I have to insert video into the site. The codec is mpeg4 (avi), I used http://github.com/zencoder/video-js as player (html5) with attributes:
<source src="some.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
This works great in Google Chrome, but not in Firefox, IE, etc. Any ideas, why? Or what I have to do? Maybe convert video to the webm or ogv? I Also tried some flash players (flow) but they don't support mp4 playing and flv quality is bad.
