07-16-2008, 7:06 ShodawN Joined on 07-15-2008 Posts 11 Network streaming: Delay Hello, I'm developing a videoconference application on VB.NET 2005 using Multimedia SDK v15. When i start the videoconference i have 1 second delay, but 20 minutes later i have 3 seconds delay. What's happend? I'm using DivX as video codec and GSM as audio codec. Thank you    Report

Also, can you reproduce this using one of our demos, or you only get it using your application? Yasir Alani LEADTOOLS Technical Support support@leadtools.com    Report

Whit your demos i have not delay increment. My code...

Please put your code in a small working project (not your full application), pack your project in a ZIP or RAR file and post it here. If you don't want to post your project here, you can email it to support@leadtools.com, and mention this forum post in the email.
