OS X and Elgato streamdeck

[mccordgh]

Hi, there! You have some great libraries for the Elgato StreamDeck on Windows.

I am wondering about Mac Support, or if you could point me in the right direction to get something going myself in C# to be able to interact with the StreamDeck (not by making a plugin). I'm trying to make a game for a game jam with the StreamDeck, and hoping to be able to bring something in to use in Unity with C#. Im on OS X.

Hi. Sure.

You could use the node implamentation (https://github.com/Lange/node-elgato-stream-deck) according to the readme it supports macOS.

If you want to write something in C# you would need a library to communicate to hid devices (with a quick google search I found Device.NET and HidSharp but I've no way of testing them.

After that you just need to send the correct payload to the library.
You can browse this library to find out what you need to send, you could for example start with this files:

• StreamDeckHardwareInfo.cs
• StreamDeckMiniHardwareInfo.cs
• BasicHidClient.cs

Let me know if you need something.

Thanks for the reply! I will try and hack on this during this week / weekend on my mac :)

Hi! I'm working on this now w/ @mccordgh.

We managed to find the device on both windows + mac using a combination of Device.Net/Usb.Net, Hid.Net, and Device.Net.LibUsb. I'll try to get the payloads working sometime in the next few days.

Would you be open to a PR that converts this to using .NET Core/Standard instead of Framework? I'm not 100% that all the current dependencies would work, though.

(I deleted and reposted this because apparently it doesn't produce notifications when you're "flagged"?)

[wischi-chr]

yea I'm open for PRs but it should still be possible to build the core stuff with .NET 4 (so you'd probably need a shared project because .NET 4.0 does not implement any .net standard.

Update: Or maybe I drop .NET 4 support I'm not sure at the moment. I'll think about it :-)

[wischi-chr]

Dropped .NET 4 support, switched to HidSharp and netstandard2. I'm not a Mac user, so I can't test it but it should work now (I guess).

Has anyone been able to get this to work? I am running this on Xamarin.Mac and getting this error:

It looks like it is related to System.Drawing.Imaging.ImageCodecInfo.GetImageDecoders (). I have the CoreCompat package installed to use libgdiplus on mac, but still getting this error.
