Hello.
I've PC (Intel Core i9-9900X), and question is how to direct all powers of 10-cores to 1 big process.
But the process is video controling on some monitors of several hundreds of simultaneously working copies of the VLC player.
I know it depends on Software of VLC
And only software dicede work with multi-slow of cores or block them and work with only one of them.
If it was blocked everything will work on one core, another's on safe mode
It's look like follow...

Hi, I didn't really understand what you're trying to achieve, but "multi-thread support" is generally not something you enable or not. What is your issue?
