Open Video mp4 on client from webserver

Trying to find a way to do instruction manual videos to be access from the client.
this videos are now on mp4. so i’m trying to open the video without the need of having to download them into the client."")

the download the video and then i can open, but everytime someone wants to vide the video it will download again. anyway to play a video without doing the dowload. like to actually open it from the file in the webserver?

got it working with

 system.util.execute(["C:\Program Files (x86)\Windows Media Player\wmplayer.exe", ""])
