This is the gaia-side patch for bug 821514.
It is based on top of the gaia patches for bug 815791, so this pull request includes two commits. It is only the second commit that we're interested in here, but I don't know how to get github to do that. The first commit will land in bug 815791, and then I can rebase this patch so that it just has the one commit we want.
But the second commit is ready for review, anyway.
Bug 815791 - separate video view activity from video player app
Bug 821514 - display error message if youtube won't play video
r+ awesome job
We dont need to split out the pull requests, they are seperate commits so it just means one less merge commit
