How to play MP4 video on window webserver in quick time and flash player(flv player)

I have two mp4 video files on webserver, i wanted to play them in flash player(flv player) on m开发者_StackOverflow社区y asp.net page, but i couldn't be able to play them, i also tried to play them in quick time player the same prob occured. but i waz giving the accurate path, there were no spaces in mp4 file names etc.

Does it need to have mp4 player(or codec etc) installed on webserver?

I have also some wmv files on that server , and i am playing perfectly using silver light player, and media player object on my website.

So please share your knowledge... thanks in advance...

You need to convert them to FLV first. I use a program called AVS Video Convertor, its not free but is a great tool.
