[whatwg] MPEG-1 subset proposal for HTML5 video codec

[Den.Molib]

I'm afraid that if using a subset of a bigger, patented, standard. 
Some browsers will include the full codec. Web authors see their videos 
reproduce correctly, and put them in the web thinking they're 'standard',
while the user agents including only the license-free version won't be 
able to view them.
Thus de facto requiring the full support for the web, in what could be 
considered a variant of 'embrace and extend' issues, even if not 
intentional.
