When doing a website, found that the video files, such as, FLV MP4 format on the local can normal to play, but reached the development machine. Player document address is right, is there has been no response.
after a long time experiment, found the problem with the iis Settings. Iis not let play video files by default, the solutions are as follows:

open iis manager on the server, the server down [the website] to find the corresponding website, right-click the point attribute,
(also can be directly right-click default website] [point attribute)
open the properties Settings window and then click the HTTP headers TAB, click the "MIME types" button,
to create a new MIME type, extension: FLV MIME types: FLV - application/octet stream -
# 0 - #

This concludes the body part
