Videos not playing in browsers

Question

I am having 6 different types of video formats, namely .avi, .mkv, .mov, .ogv, .wmv,

Answer 1

To cover most situations convert each video to an Ogg, Webm and MP4 version, display it on a web page using:

For IE8 and earlier use flash (see http://videojs.com)

For IE9 the preload tag must be present and set to auto or none.
