I propose that a MPEG-1 subset should be considered as the required
codec for the HTML-5 video tag.
== MPEG-1 Background ==
MPEG-1 was published as the ISO standard ISO 11172 in August 1993. It
is a widely used standard for audio and video compression. Both
Windows Media and Apple Quicktime
That is a potential problem, but for MPEG-1 it is less of a problem than with
newer codecs. Since the near complete MPEG-1 committee draft was publicly
available in December 1991, remaining patents for decoding of the full MPEG-1
spec should be expiring in the 2012 timeframe or before.

There are concerns or issues
I read section 4.8.7 The video element and I have some questions:
1. What happens if the user agent supports the video tag but does not support
the particular video codec that the video file has? Should it display the
fallback content in that case, and if so, can a video tag be put inside
Okay. Thanks.
Maybe to make this more clear section 4.8.7.1 should add a sentence somewhere
like:
Authors may provide multiple source elements to provide different codecs for
different user agents.
Thank you.
