I am rather familiar with HTML; but, very new to playing (viewing) videos in an HTML document. When testing my HTML code (e.g. what has been posted at http://camendesign.com/code/video_for_everybody ), I use FireFox 25 to display it. This works fine for nearly everything I have written in HTML; but, I have yet to succeed in playing any video in FireFox --- no matter what I put in my HTML code. And yes I have read what is posted at many Web locations that address video related problems in HTML documents. It could be related to the parameters that one must set (e.g. .htaccess); but, where and how do I set these parameters? I would be glad to provide any additional information that might be useful for the solution of how to play videos in an HTML document. Note, I have tried this on both Windows Vista (32-bit) and Windows 7 (64-bit) platforms.
I should add that my application is as follows. I create an HTML file that contains code to play a video. This file (along with the video) is sent to someone else. I would like for the person to be able view this HTML and video in FireFox 22+, IE 9+ on their Windows Vista+ system. That is, it is a sort-of tutorial in HTML that contains embedded videos. So far, I have been unable to get it play a video on any of my PCs during development.
