Is there a list of browser support for various video formats?

Solution 1:

If you're asking which browsers codec support for the HTML5 <video> tag, the Wikipedia entry for HTML5 Video is fairly informative (taken 5th May 2013).

It looks like Theora and VP8 are the most widely supported right now.

Solution 2:

Video formats:

• Internet Explorer 9+, Chrome 6+ and Safari 5+ can play MP4's (type="video/mp4")
• Chrome 6+, Firefox 3.6+ and Opera 10.6+ can play WebM's (type="video/webm")
• Chrome 6+, Firefox 3.6+ and Opera 10.6+ can play OGG's (type="video/ogg")

Audio formats:

• Internet Explorer 9+, Chrome 6+ and Safari 5+ can play MP3's (type="audio/mpeg")
• Chrome 6+, Firefox 3.6+, Safari 5+ and Opera 10.6+ can play WAV's (type="audio/wav")
• Chrome 6+, Firefox 3.6+ and Opera 10.6+ can play OGG's (type="audio/ogg")

I wish there was at least one type of video & audio they all supported, and I wish they could all play .mid files and .avi files.
