Question / Help Numeric hotkeys not working on Windows OBS studio

Naweo · Sep 13, 2016

Hello!

I was only able to find this problem in the MAC forums, but I have the same problem with windows.

Numeric hotkeys do not work while OBS studio is not active.

Is there a fix to this?

Thanks! =)

Admin mode?

Heya!

Yeah I have set the compaitibility mode to run as administrator, my user account on windows is an administrator, and it does not seem to work.

What actions? Scene switching? Please, post a log.

Naweo · Sep 13, 2016

Scene switches, though I would like to note that I am using a keyboard without a numeric pad so I am using a autohotkey script to execute those keyinputs, I will try testing a different input method and see if that works, could be that OBS studio does not register such key inputs from the script I have running. If I use any hotkey that my keyboard actually has physically then it works.

If that does not work I will get back to you with a log.

So, you cannot setup hotkey at Settings>Hotkeys ?
Also, try to run autohotkey with admin rights too.

Naweo · Sep 13, 2016

Well I can make the hotkeys, but they do not seem to work, even when Autohotkey is run as administrator hmm

Suslik V · Sep 13, 2016

So strange, I can trigger any action in OBS Studio even using on-screen keyboard. Post a log where you are switching scenes and it doesn't work.

Naweo · Sep 13, 2016

Alright, uploaded a log file. It simply does not register my input at the end. Please let me know if you find anything, I appreciate it.

On-screen keyboard works for me too, but I am trying to use Autohotkey to send keystrokes automatically, though I am not sure which input to use to make it work with OBS studio, provided that it is possible.

Suslik V · Sep 13, 2016

Have you an autohotkey script (.ahk file or post it as .txt, please)? I can test it on my side.

Naweo · Sep 13, 2016

Sure, I will make a simpler version as the one I have now is quite heavy, give me 2 mins please

- It did not want to let me upload, so here is the short version. Basically just make two hotkeys for NUM1 and NUM9 and see if you can make it register with autohotkey.

I don't like few parameters from your script (HotkeyInterval and MaxHotkeysPerInterval values for example) but
let's test it like this:

Code:

Send, {Numpad1 Down}
Sleep, 10 ; pause 10ms to allow application to recognize the pressed state
Send, {Numpad1 Up}

or "compile" this scripts with AutoHotkey (make exe):

Code:

; OBS Studio existing keys test (Studio v0.15.4, ahk v1.0.47.3)

; Start loop as auto-execute, loop until ScrollLock is pressed!!!
; Infinite loop!!! Simulates f3, f6 keypress at ~3 sec intervals

Loop {

Send, {F3 Down}
Sleep, 10 ; pause 10ms to allow application to recognize the pressed state
Send, {F3 Up}

Sleep, 3000

Send, {F6 Down}
Sleep, 10 ; pause 10ms to allow application to recognize the pressed state
Send, {F6 Up}

Sleep, 3000
}

;;;;;;;;;;;;;;;;;;;;;;;;;

; Pause timers and loops on ScrollLock press.
ScrollLock::
{
Pause
}
return

Code:

; OBS Studio non-existing keys test (Studio v0.15.4, ahk v1.0.47.3)

; Start loop as auto-execute, loop until ScrollLock is pressed!!!

Loop {

Send, {F13 Down}
Sleep, 10 ; pause 10ms to allow application to recognize the pressed state
Send, {F13 Up}

Sleep, 3000

Send, {F16 Down}
Sleep, 10 ; pause 10ms to allow application to recognize the pressed state
Send, {F16 Up}

Sleep, 3000
}

To setup non-existing keys in OBS Studio use this script:

Code:

; OBS Studio non-existing keys test assignment (Studio v0.15.4, ahk v1.0.47.3)

; assign f1-f12 to non-existing on my keyboard f13-f24

F1::F13
F2::F14
F3::F15
F4::F16
F5::F17
F6::F18
F7::F19
F8::F20
F9::F21
F10::F22
F11::F23
F12::F24

;;;;;;;;;;;;;;;;;;;;;;;;;

; Let's program the script suspend by ScrollLock press,
; (for easy script termination when important keys in use).
ScrollLock::
{
Suspend
}

Please, replace all "ScrollLock" strings from the scripts with key that exist on your keyboard (by pressing it you pause or suspend script from execution).
Simple scripts simulates f3, f6 keypress at ~3 sec intervals (or F13, F16)
"Advanced" scripts has 2 loops: one loop triggered by F1 key and stopped by F4 key, another loop running infinite (test F2 key press or any other statement) from the beginning.

P.S. About auto-scene switcher plugin it was added: https://github.com/jp9000/obs-studio/commit/39592ff5ebb9aa641ae460b7c044e3fc1cc0196f , wait for new release.

Actually I fixed this by executing a controlsend command instead of a send command, although it is a bandaid!

Thanks anyway! :)
