Is there a way to edit the x264 settings this plugin uses?

As the title says, is there? I can't seem to find how to do it, or what version of x264 it's even using when encoding mp4 videos.

you can find out by running mpv -ovcopts help and looking for the Additionally, for libx264: section. the same applies for all the other video codecs' additional flags: libvpx for VP8, libvpx-vp9 for VP9, and h264_nvenc for H.264/NVENC.

I just went through this myself, so i'll save you the trouble—this is as of v0.33.0-397-g4a80de90d2 webm_ovcopts.txt

EDIT: whoops, forgot to tell where you put these opts—they go in the additional_flags section of your webm.conf, i.e. additional_flags=--ovcopts=aq-mode=3
