No. The Sonos ‘app’, or controller, doesn’t handle video at all. You might try setting up your Sonos speakers as computer speakers, there’s a lot of good information here. 

Then you could play the video on your computer, and have the OS to ‘throw’ the resulting sound to Sonos. 

Good information to have, still not what I was looking for, but thanks!

You’re looking for computer speakers, not something that Sonos has gotten in to the market on. So far, at least. There are a lot of other devices out there, it’s probably a hard market to get in to.  While there are workarounds in the link I provided above, it doesn’t really meet their ‘whole home’ idea very well.
