Fullscreen video and fullscreen swf does not work in public_html ,why?

Good evening,

I am currently working on fullscreen video and fullscreen swf for two different project.
I set the width and height to 100% and padding all 0,
For the video, i have .webm and .mp4 format

When i view in localhost or double click the index.html, both work nicely and fine in all browser.
However when i upload everything to public_html, and view from a url,
the video keep on jerking and stopped in safari and chrome.
for firefox ,it couldnt play ,show a white screen.

The swf when view from
chrome became 1/3 of the screen.
safari work fine
firefox show a white screen

Browser are updated to the latest version
How do i solve it? Is there an explanation behind it?
