Cast to device context menu is empty, but can cast from YouTube

I can cast from YouTube on my Wi-Fi connected laptop with no problem, but when I right-click an MP4 file and hover over the Cast to Device context menu item, I get a never-ending Searching for devices... status.

I'm not sure what to make of this. Since I can cast YouTube without any problem, shouldn't I just as easily be able to cast an MP4 video?

How can I watch an MP4 video in the same manner as I watch YouTube?


Solution 1:

I have also run into the same problem, of being unable to cast a video by using Windows.

My solution was to display the video in Chrome and use Chrome's Menu > Cast... command. This method works as well for YouTube, so might be the one that already works well for you.
