Asp.net FMS develops video website

Development steps:
1. Download FMS http://blogs.ugidotnet.org/kfra/archive/2006/10/04/50003.aspx , install and configure.
2. Use flash to create controls for FMS video collection.
3. The aspx page embeds the FMS collection control, runs the collection data to upload to the FMS server, and modifies the video file storage address of the database.
4. The page embeds Flash playback control and adds FLV processing stream code:

1using System;
2using System.IO;
3using System.Web;

95 Modify the configuration file and run the page to call up the video. The playback speed is very good. Although it is an understatement, the idea of ​​using Asp.net to develop a video website has been given. If interested please contact me.
