emby manual compile imagemagick without openmp

[jody 4]

Hi ppl, 

I'm doing a manual install of emby and on the download page under manual it says:

Install Dependencies

• mono 3.4 or above
• sqlite3
• MediaInfo
• ImageMagick (preferably Q8, without OpenMP, without HDRI)
• arm users will need to install ffmpeg (including ffprobe)

Why ImageMagick without OpenMP? OpenMP is for multicore CPU support so on a multicore CPU it would speed things up or is there a specific reason for it?

thanks in advance

OpenMP provides multithreaded processing of individual images. It's great for large images, but can degrade performance when working with large numbers of smaller images.

 

For Emby it is more ideal to have multiple threads each processing their own separate images rather than the other way around.
