How to make my mp4 play without vimeo

Hi

I want to upload a mp4 video onto my wordpress page. I added the media onto the page but when I go to view it, the video does not play. It stays on the first frame and it does not move forward.

Instead, if I load the video on vimeo and embeed the link into the page, it works indeed. Why? If my option is to use Vimeo then, I would like to remove author, title and image. I came across a post where a member suggested to add the following jquery:

jQuery('#MyContainerID iframe').attr('src', function() {
	  return this.src + '?title=0&byline=0&portrait=0&color=ffffff'
	});

where do I need to add this code? I would also like to remove the share option from the video. Is it possible?

The third option that would resolve all my problems is to use dropbox. But after having uploaded the video and entered the link into the page, the video does not play at all. Would anyone be so kind as to help me out?

Thanks
M
