How to install the custom OBS build?
In order for the playlist to not restart from the first file whenever settings are changed, this custom OBS build is needed. However, I can not provide a Windows installer (other than the zip).
Before proceeding with any of these installation steps, please back up your scene collection in OBS by clicking Scene Collection > Export.
You can then select where to save the backup.
To restore the backup, just click Scene Collection > Import and select the backup file.
A portable OBS installation saves the OBS profiles and scene collections to the same folder as the OBS folder, which means that existing profiles and scene collections in the normal OBS installation will not be used, as if you made a new user. Download obs-studio-windows-x64-4c46db596.zip. Right click the zip, then extract the contents.
Inside the zip, there is another zip. Repeat the extraction process.
IMPORTANT: Next, open Notepad and save it with the filename "portable_mode.txt" (keep the contents empty), in the obs-studio folder.
Note: If you run OBS without this file, it will use the existing scene collections but without the other plugins you have already installed, which can cause you to break your setup. If you manage to break it, you can import your backup.
Then, open the bin\64bit folder, and right click 'obs64.exe', and click Create Shortcut.
You can double click that shortcut to run the program, and you can move that shortcut anywhere you want. If you prefer, you can also move the created folder anywhere you want.
This basically applies an update to your existing OBS folder, so you would be able to access your existing profiles and scene collections.
Follow the downloading and extraction steps above, then simply copy the "bin", "data", and "obs-plugins" folders to the existing OBS installation, overwriting the contents of the folder.
Should you wish to revert to the original OBS version, you can simply re-run the official OBS installation.
