What location shows in your browser when you access the html file ?

file:///home/ubuntu_workspace/c/test.html
[download]

Is this you are asking?

This is why it works and what Corion already said. The video serves because the context is the file:/// tree. But once you serve the HTML through any kind of webserver, the path to the video will not exist in that context. Probably one of these will work but it depends on the type and configuration of the webserver you are using–

<source src="video.mp4" type="video/mp4">
<source src="c/video.mp4" type="video/mp4">
...etc...

Maybe shouting will help :D

file:// IS NOT THE INTERNET, file:// IS NOT HTTP, file:// IS NOT CGI, file::// IS NOT THE INTERNET

http://.... is the internet

http://....cgi is the internet

http://....mp4 is the internet

Your webserver maps ...cgi to a directory on your harddisk ( like /home/foo/bar )

/home/.../cgi-bin maps to http://.../cgi-bin

/home/.../public_html/foo.html maps to http://.../foo.html

FYI

Every perl/CGI problem can be solved if you work through these checklists, when you find a problem on the list, use a solution from the list, when you find a problem not on the list (rare), post the error message and problem description here
