OSC Messages from CasparCG Server 2.3.x

I am developing a client application in standalone VB.NET (form appliation using .NET framework) connecting to CasparCG Server 2.0.7, 2.1.x and 2.3.x versions.

I receive OSC messages using Bespoke.Common.dll and Bespoke.Common.Osc.dll. I use UDP with port 6250. With server versions 2.0.7 and 2.1.x I receive OSC messages flawlessly and promptly. I use them to build a video playlist. I have been using them for the past 4-5 years without any issue.

But when I use CasparCG Server 2.3.x (with the same code) the OSC messages arrive at the application very very late. Sometimes they are received after 6-10 seconds later which make them effectively useless data. (The AMCP commands are working promptly. There is no issue with the AMCP commands.)

Why this behaviour? Has any one faced this? How to correct?

Thanks in advance…


Using it a lot and have no issues like this. C# wpf don’t remember which OSC lib I use, can check it next week.


You have to use a background worker to process the OSC data
