I don't see why this would be mpv's fault, since it's your antivirus snakeoil thing misbehaving.

[sethazazel]

i am not saying it's mpv's fault just i don't get it why windows services (not only antimalware) use too much cpu when mpv working. when i play same video with smplayer and potplayer nothing unordinary happens

[garoto]

Try a couple previous shinchiro builds to isolate the issue to this specific build perhaps.

[sethazazel]

I tried previos versions and there was no problem. But when i copy my scripts to scripts folder same problem showed up. I delete mpv_thumbnail_script and problem was gone.https://github.com/TheAMM/mpv_thumbnail_script

Thanks for helping me. Please feel free to close the issue.
(if you know any alternative for mpv_thumbnail_script please inform me.)

[Akemi]

you can close your own issue.

[sethazazel]

i didn't know that, i am newbie. Thank you.

This probably happens because Windows is a terrible OS and has gigantic
process creation overhead that gets even worse when the antimalware shit is
involved. Of course the script should try to avoid spawning a process for each
thumbnail it wants to create, but that’s a different problem…
