Question / Help Emulated keystrokes

[xavierm02]

Hi,

I have a G751 so I have extra keys on the keyboard, including one (that I'll call CAMERA) to toggle record. It's supposed to work with Shadowplay but Shadowplay isn't quite usable yet so I use OBS instead. So I rebind the key using some piece of software that allows to either run a program with the key is pressed or simulate a Ctrl + Alt + Shift + Something keystroke.

My problem is that I can use that key to set put that keystroke in the shortcuts settings but when I try to use it afterwards, it doesn't work. In other words, both CAMERA and Ctrl + Alt + Shift + S work in the settings of OBS but only Ctrl + Alt + Shift + S works to actually start the stream.

I also tried make a program to make the keystroke myself using https://inputsimulator.codeplex.com/:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WindowsInput;
using WindowsInput.Native;

namespace Keystrokes
{
    class Program
    {
        static void Main(string[] args)
        {
            IKeyboardSimulator keyboard = new InputSimulator().Keyboard; System.Threading.Thread.Sleep(1);
            keyboard.KeyDown(VirtualKeyCode.LCONTROL); System.Threading.Thread.Sleep(1);
            keyboard.KeyDown(VirtualKeyCode.LMENU); System.Threading.Thread.Sleep(1);
            keyboard.KeyDown(VirtualKeyCode.LSHIFT); System.Threading.Thread.Sleep(1);
            keyboard.KeyDown(VirtualKeyCode.VK_S); System.Threading.Thread.Sleep(1);
            keyboard.KeyUp(VirtualKeyCode.VK_S); System.Threading.Thread.Sleep(1);
            keyboard.KeyUp(VirtualKeyCode.LCONTROL); System.Threading.Thread.Sleep(1);
            keyboard.KeyUp(VirtualKeyCode.LMENU); System.Threading.Thread.Sleep(1);
            keyboard.KeyUp(VirtualKeyCode.LSHIFT); System.Threading.Thread.Sleep(1);
        }
    }
}

I used the solution of this thread to avoid having a prompt showing up: http://superuser.com/questions/140047/how-to-run-a-batch-file-without-launching-a-command-window

And I have the exact same problem: it works to set it in the settings but I can't use it.

I guess it has something to do with focus. When I'm in the settings, OBS captures everything while the rest of the time, it doesn't. But I don't get why even when I focus the OBS main window, it doesn't work.

Please let me know if you know some way to fix this.

Thank you in advance for your answers.
