youtube embed video wrong dimensions

[Alexufo]

1. try to embed ​http://www.youtube.com/watch?v=5EayDPIjp40 at default wordpress theme.

2. You will see 4:3 but not originally 16:9. I didnt know why videos embeds differently. This video has error of embed height.

Confirmed. These are the parameters sent to YouTube using Twenty Fourteen:

array( 'width' => 474, 'height' => 711, 'discover' => false )

This what we get back from YouTube:

<iframe width="474" height="356" src="http://www.youtube.com/embed/5EayDPIjp40?feature=oembed" frameborder="0" allowfullscreen></iframe>

The correct height for a 16:9 video would be 266px here, but this looks like a YouTube issue.

This loads in 2014 theme as 474 x 232 now, so problem solved. I admittedly don't know when this was fixed...
