I could not get to your staging site because it requires a user name and password. Anyhow, browsers download content when they do not know how to display it. That means a browser either needs to know how to handle MP4 natively or there needs to be a plugin installed that does that. A lot depends on the browser that you use, some support more formats natively than others.
Also, most browsers support mp4 only when it is encoded as H.264. For other mp4 encodings it looks as that it is necessary to have Apple Quicktime installed for a browser to display the video inline. While searching online I also came across this page:
http://camendesign.com/code/video_for_everybody . They provide HTML5 code that makes use of the HTML5 video tag. That is supported by most modern browsers, see here:
http://caniuse.com/video
All these options do without the MadCap specific attributes, which may or may not be a benefit.
I also wonder about this:
Code: Select all
src="Resources/Multimedia/config eform.mp4"
There is a space in front of "eform.mp4". Does the file name of the mp4 contain a space or is there a slash missing? If the slash is missing the browser might interpret the source attribute as folder and thus show something else than expected. In case the file name does contain a space, try removing it or replacing it with an underscore and see if that makes things any better.
Hope I could help.
