Viewing lecture videos on a different screen via Chromecast

Hi team. I would like to know whether it is possible to “cast” lecture videos on a different screen via Chromecast like Netflix? It would be cool if this feature is available as I sometimes travel to a different state for holidays and there is nothing worth watching on tv in a hotel room. Thanks.

If you download lesson videos I do not see why it shouldn’t work, else, lessons are played by the browser, I am not sure that browser can cast videos onto the TV.
