Problem with Video.js PlugIn

I get the following error message when using the Video.js Plugin.
I tried with different mp4 video files as well as with dynamic and static video sources (all hosted on AWS)

“The media could not be loaded, either because the server or network failed or because the format is not supported.”

What I am trying to achieve is a video upload via file uploader and displaying the video afterwards.
YouTube links work.

Any help is much appreciated.


I finally found a file which woked…Now I know it is generally working however I need to gather the details of the supported file types. Solved for me.
