hi, I am working on a project and I am stuck on video uploading. I need to post a message, image, and video dynamically as done in Facebook. I can successfully send a message to different user connected in LAN. Also the images get uploaded in database and get displayed on web page at run time. Now I need to upload videos at run time.
I have written the code given in the link below
http://www.aspsnippets.com/Articles/Upload-Save-Retrieve-and-Play-MP4-Video-files-with-live-streaming-from-Database-in-ASPNet-using-C-and-VBNet.aspx
but this code does not work. nor does the web video get saved in database.
Can any one help me with the sample code to upload/post the video on webpage which can be visible on multiple browsers..... I have used a generic handler.
(Let me know if my question is improper.)
