PowerPointToOBSSceneSwitcher

A .NET core based scene switcher that connects to OBS and changes scenes based note meta data. Put "OBS:Your Scene Name" on its own line in your notes and ensure the OBS Web Sockets Server is running and this app will change your scene as you change your PowerPoint slides.

Note this won't build with "dotnet build," instead open a Visual Studio 2019 Developer Command Prompt and build with "msbuild"

This video explains how it works!

Usage

• Set a scene for a slide with

OBS:{Scene name as it appears in OBS}

Example:

OBS:Scenename

• Set a default scene (used when a scene is not defined) with

OBSDEF:{Scene name as it appears in OBS}

Example:

OBSDEF:DefaultScene

UPDATE: For many this just clones and builds, but for some folks (unknown why) it doesn't.

CI/CD Pipelines failing in my private repository.

I cloned this repo and set my remote as a private repository. I setup a CI/CD pipeline to build the project

But I am getting these errors:

##[error]Program.cs(4,17): Error CS0234: The type or namespace name 'Office' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)
##[error]Program.cs(30,50): Error CS0246: The type or namespace name 'SlideShowWindow' could not be found (are you missing a using directive or an assembly reference?)
##[error]Program.cs(11,24): Error CS0246: The type or namespace name 'Application' could not be found (are you missing a using directive or an assembly reference?)

What am I doing wrong?

Thanks!

LAN support

Hi,

Big fan of this awesome piece of code. I'm curious if there is a fix for the "thing" I'm running into.

I'm using 2 laptops, 1 for presenting and 1 for streaming, the presenterfeed is send to the stream pc via NDI.

How can I enable this scene switcher to communicate with OBS on the other computer within the same LAN network?

I have tried to change the localhost ip into the other computers name and also tried the IP but this doesnt seem to be enough to make it work.

Any suggestions?

Can't advance slides in PowerPoint

When the PowerPointToOBSSceneSwitcher console application is running and I start the slideshow the first slide appears and OBS switches to the correct scene. However powerpoint has lost control, as in I can't advance to the next slide with a key press or mouse click until I exit the console app.

Steps to recreate

• Run PowerPoint (in my case PowerPoint 2019, not O365 version)
• Load up my freshly creately PPTX file with the OBS:Scene1, OBS:Scene2, etc
• Open OBS Studio
• Run PowerPointToOBSSceneSwitcher (I've tried running from VS2019 and as a publish console app)
• Start SlideShow

OBS switched to Scene1 correctly and on my first monitor the slideshow starts.

But I now can't advance to the next slide.

Ideas?

It doesn't build with msbuild

error CS0246: The type or namespace name 'ObsWebSocket' could not be found (are you missing a usi
ng directive or an assembly reference?)

App crashes if Scene name not found in OBS

The app throws an exception if the scene name in powerpoint can't be found in OBS

error NU1101

I always get this error after try to build yout code to an exe:
error NU1101: Unable to find package OBS.WebSocket.NET. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages
