LD_PRELOAD in Windows?

[baesek]

How or can i use this script for OBS running on Windows 10? I tried to follow your instructions, but I don't know how to start OBS with LD_PRELOAD. I assume I somehow have to put the line C:/Program Files/Python37/python37.dll somewhere.

I use Debian and I have a Windows 10 partition to test... but, before rebooting my computer and test it by myself, try this: https://support.shotgunsoftware.com/hc/en-us/articles/114094235653-Setting-global-environment-variables-on-Windows. If it doesn't work, tell me: we gonna find the way.

Hi Mario! Thanks so much for your fast response. This is what I tried, I added your script in the Tools/Scripts menu of abs and added the path to my python installation in the next tab there too. (C:\Program Files\Python37) then I ran the code on the left bottom of the screenshot below. But the scene did not change by doing so. Greetings from Hamburg, Germany

Someone from Python Argentina Telegram channel told me what to do: in OBS, go to Tools -> Scripts -> Python Settings and configure path there.

[baesek]

(changed my username...) Okay I found out, that I have to install Python 3.6 instead of 3.7. After adding the path (C:/Program Files/Python36/) to theTools -> Scripts -> Python Settings, I get a Scripting log which says:

[obs_osc_pythonscript.py] Traceback (most recent call last): [obs_osc_pythonscript.py] File "C:/Users/User/automat-display/obs/obs-osc/obs-osc-pythonscript-main\obs_osc_pythonscript.py", line 36, in [obs_osc_pythonscript.py] from obs_osc_api import ( [obs_osc_pythonscript.py] ModuleNotFoundError: No module named 'obs_osc_api'

[baesek]

I could somehow get it working now by changing some lines in obs_osc_pythonscript.py

"""
from obs_osc_api import (
    scene_change, 
    consola, 
    consola_hslider, 
    c1, c2, c3, 
    c, 
    th
)
"""

from obs_api import (
    # I inserted these 5 from the obs_osc_api import above
    consola, 
    consola_hslider, 
    c1, c2, c3, 
    c, 
    th,

    scene_change, 
    item_set_visible,
    item_remove, 
    item_duplicate,
    item_reference,
    item_set_transform,
    item_get_transform,
    item_set_pos,
    item_set_scl,
    item_set_rot,
    item_set_alignment,
    item_set_visible,
    item_set_crop,
    item_set_scl_filter,
    item_get_order_index,
    item_set_order_index,
    item_swap_order_index,
    item_set_private_setting,
    item_create_group,
    item_create_text,
    item_create_image,
    item_create_video,
)

After that i had to install two python packages for my python36 installation to get it working by entering the following lines into a powershell which was run as an administrator

C:/Program Files/Python36/python.exe -m pip install requests
C:/Program Files/Python36/python.exe -m pip install pillow

I also removed LD_PRELOAD from my windows environment variables and it still worked...

[MarioMey]

So... does it work? Congratulations!

[baesek]

Yes! Super cool script and super fast! Thank you for this. I am just wondering how to find out what commands are possible. For example setting the projector the fullscreen via an osc message.

[MarioMey]

Well... no, I didn't do that. My scripts (you can see in action in IG @videoconfestejo) are for treat OBS as a game engine: almost all the functions are for manipulate sceneitems and scources. Creating them, transforming them, removing them, etc.

Check https://github.com/upgradeQ/OBS-Studio-Python-Scripting-Cheatsheet-obspython-Examples-of-API for more commands.
