Description

For whatever reasons the script is extremely sluggish and/or stuck with this - Chuunibyou demo Koi ga Shitai! Ren by Kametsu (or more) specific release. The script is working fine with my other files. I am not sure if this is mpv fault, script fault or encoders' fault (file plays normally in mpv).

Seems like a broken file, I guess. You should probably report this to the mpv repo itself. Here's the command line if you want to reproduce the issue without using this script (you could drop a lot of the options, and the parameter escaping is probably borked, but it might help a bit):

Looks like it was fixed before I even updated mpv, thanks for looking into it. No issues with it with the following mpv version:

Well, I'm happy it fixed itself..? Anyway, I'll close this then, feel free to reopen if the problem appears again.
