I have a mkv file. It's video codec is avc and audio codec is ac3.
How can i put it into a html5 video tag?
I use the
<source src="01.mkv" type="video/x-matroska" codecs="a_ac3, avc">
but in safari 5 or chorome4 it doesn't works.
Your <source> tag is malformed. You need to put the codec information inside the value of the type attribute instead, eg:
<source src="01.mkv" type='video/x-matroska; codecs="a_ac3, avc"'>
The type attribute contains a full MIME specification, and codecs is an optional parameter for some MIME types. There is no separate codecs attribute on the <video> tag.

<source is not the top level HTML5 video tag, which is named <video>. You can find out more from this tutorial. Are you using <source> inside of <video>?
