According to a Google+ post on Saturday by Francois Beaufort, Chromium Evangelist at Google, the 'last Dev Update of Chrome OS' (found here) includes the updated Video Player app for Chromecasting movies directly from their Google Drive accounts, as well as an updated version of the File Manager.
Now Chrome OS users can simply open the Files app, select the Drive section, play a movie and they will see the new Chromecast icon in the Video Player app to cast it to a big screen with the help of Chromecast dongle. Those who don't see the new Chromecast icon will have to first install or enable the Google Cast Extension.
