I am trying to play a mp4 file from my server on google chrome. but nothing hapens when press play, it lights up for a split second (which shows the does exist) but then fails to stream. If I enable divx webplayer extension on chrome it plays it through divx player, however I need it to be possible to play it without that extention. here is the code I am using:
<video width="560" height="340" controls>
<source src="hood.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2" '>
</video>
Semi-answer: try and use JWPlayer it plays pretty much anything and it automatically downgrades if needed. (Using HTML5 or Flash)
