That depends on the device you’re using.
Any Android smartphone should start playing without a problem. Also on a regular Windows or Mac computer the video should start playing without problem.

iPhone or iPad
iOS doesn’t play MP4 files by itself, for this you need to install an app.
There are several apps that you may download from the App Store, like PlayerXtreme.
With PlayerXtreme you can play the video’s from a url or from your desktop of laptop.
However, if you only have handheld devices like an iPhone or iPad, you’d better download the video before watching it.
For downloading you need another app, e.g. File Manager.
For playing a video that you have downloaded with the File Manager app, just click it. If the result is a play button on a black screen, then click on the icon at the right top of the screen, select “Open…” and then chose “Copy to PlayXtreme”.
