Hi Eric,

Currently not, since Android is the only platform that currently returns true
for canLoadPoster(). However, I expect that other mobile platforms may have the
same problem and may need this.

>Do other <video>
> implementations use the poster image?  

Yes, all of them. It is part of the spec.

>Why does android need it?  

The problems is as follows: currently the HTMLVideoElement creates a
RenderImage and loads the poster. This poster is shown on the page (where the
video should render) until the media player has buffered enough content and is
able to generate a thumbnail based on the first few frames of the video. 

However, this doesn't work for our player, which cannot currently generate such
a thumbnail. On the other hand, if the user has specified the "poster"
attribute, our player can just show the user-provided poster instead. In order
to use it, it needs to know its URL. Hence this change.

>And why can't
> we test this?  

I wasn't entirely sure how to test this. As I said above, we're the only
platform that returns 'true' in canLoadPoster() so all other platforms are
currently unaffected by this change...Do you have a suggestion?


>the OOPS! in your ChangeLog will cause this to fail to land.

Oh, I did not know. I will just remove it if we agree what to do about testing.

Thanks,
Andrei
