How to use only one core when encoding

[JesusChavezArias]

Hi, I'm a bit new to the Python language, so I would like to know if when coding in a .heif/heic image I can use a single core/thread of my CPU, because I don't want my processor to be at 100% in a task like this.

Thanks and sorry for my bad English.

Hi, of course you can pass encoding options to .heif/.heic for the x265 encoder. I don't think it's all tested, I'm doing some small autotests on it, but this is the first question about encoder options.
So if something doesn't work, ask in this repository and we'll see what's wrong.
Here is a thread control option i found: option-pools

im = Image.open("input.png")
im.save("output.heic", enc_params={"x265:pools": "0"})

Note: Since x265 is a video encoder and we are working with images, we are always working with one frame.

Starting with version 0.9.0 I will add simpler options for this and for managing number of decode threads, stay tuned.

Thanks for the solution, I will keep an eye on future versions of pillow_heif.
