asp.net FMS Development video site

Development steps:

1. Download FMS http://blogs.ugidotnet.org/kfra/archive/2006/10/04/50003.aspx, installation configuration.

2. Use Flash to make FMS video capture controls.

3. The ASPX page embeds the FMS collection control, runs the collection data to the FMS server, modifies the database's video file storage address.

4. The page embeds the Flash playback control and adds the FLV process Flow code:

Modify the configuration file, run the page to pull out the video, playback speed is very good. Although the understatement but has given the application asp.net development video website idea. If you are interested, you can contact me.
