Null Refrence Exception in Encoding Thread

[Platratio34]

Overview

I basically copied the code from the GUI example (witch was working with the same versions of everything), and when I run it I get a null reference exception when I try to connect to a mumble server. It is connecting to the mumble server, witch is the uMurmur server integrated in CitizenFX Framework (FiveM/RedM), and I have confirmed that it did actuality join with a standard client also in the server. There is also about a 5 second delay from when I run the connect function, and when I get the error, and it receives 7 messages during that time.

Stack Trace

Can you please check that opus.dll is copied over in the output Subfolder "\Audio\Codecs\Opus\Libs\32bit"

[Platratio34]

There is an opus.dll at bin\Debug\net6.0-windows\Audio\Codecs\Opus\Libs\32bit\ as well as one in the 64bit folder. I am running it in VS Code.

The Nuget package has been updated to v2.0.1 so that the needed codecs files opus.dll are automatically copied to the output folder of projects referencing the nuget package, this should solve your issue. Please report if it did solve your issue or not, thanks.
