How to play MPEG4 Visual with HTML5 <video>?

Question

I currently use this to play AVC (H.264 or MPEG-4 Part 10) videos.

<video controls preload>
  <source src="xyz.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
</video>

However, that doesn't work for MP4V (MPEG-4 Visual or MPEG-4 Part 2) videos. I tried codecs="mp4v.20.8, mp4a.40.2" but that doesn't seem to work either.

Does any of the major browsers support MP4V in HTML5 <video>? If yes, what type/codecs should I specify in the <source> tag? Alternatively, do Flash players like flowplayer support MP4V?
