Yeah, how should a text browser render <video>? If we look at <object 
data=image.jpg>fallback</object>, then it presents the fallback. 
Whereas for <img alt="fallback"> it renders the alt text in a different 
color. 

3 options: 1) Behave like for <object>. 2) Behave like for object but 
still color the text or something. 3) Treat <video> more or less as an 
image map: Introduce a @alt attribute on <video> which is meant to 
represent the video including the first frame. By pressing the video 
element, the user can download the content of the src attribute. If the 
video contains multiple video formats and/or fallback, then let the 
user "open" the video element and navigate inside it to select video 
format to download and read the fallback.

Thoughts?
