vo=libmpv OpenGL invalid enum

[eyalmazuz]

I'm using Anime4K in MPV and I thought about adding it to memento as well
but when I run memento with the shaders (even when not activated by default)
I get the following error:

~/D/J/A/[Judas] Kimetsu no Yaiba - Mugen Ressha-hen [1080p][HEVC x265 10bit][Multi-Subs]> memento \[Judas\]\ Kimetsu\ no\ Yaiba\ -\ Mugen\ Ressha-hen\ -\ 05.mkv
AO: [pipewire] 44100Hz stereo 2ch floatp
VO: [libmpv] 1920x1080 yuv420p10
[libmpv_render] after creating texture: OpenGL error INVALID_ENUM.
[mpv_thumbnail_script_client_osc] The 'tick' event is deprecated and will be removed.
[libmpv_render] before loading program: OpenGL error INVALID_ENUM.

I also getting this error when trying to use the mpv thumbnail script
But to fix this I can add to the mpv.conf vo=gpu-next isn't compatible with memento since causes other problems

is there a way to fix the OpenGL error?
or is there a plan for future support of other --vo= options?

Looks like it's a problem with Anime4K being incompatible with vo=libmpv. I'd report this to either mpv or Anime4K and get their opinion. There's not anything I can do to fix this.

or is there a plan for future support of other --vo= options?

This will never happen because Memento uses libmpv and vo=libmpv is the only supported vo.

I tried updating to the latest memento-main
and I'm getting the OpenGL error without any script/shaders added
on a very clean install

I'm suspecting it might not be a anime4K issue(?)

Edit:
I'll add that I tested memento on X11 (I'm usually using wayland)
and the Issue still persists, so it's not a wayland issue for the very least

I'm also observing this error on a fresh clone, build & install of this repo; even without Anime4k shaders installed. Running on Manjaro Linux x86_64.

I can verify that it's happening on mpv v0.38.0 without any shaders. Looks like a bug in vo=libmpv. I'll try to collect more information and make a report to mpv.

This issue is being tracked at mpv-player/mpv#15019

Update: with MPV 0.39 (?)

suddenly anime4k works without issues
had to change the shortcuts to ctrl+3-9 instead of ctrl+1-6 + ctrl+0

cause apparently memento uses ctrl+1 and ctrl+2 for subtitle sizes and ctrl+0 to hide/display subtitles

but running memento with the shaders, I can switch between and clear the shaders without issues (at least it looks like it's working)

I still get

[libmpv_render] after creating texture: OpenGL error INVALID_ENUM.
[libmpv_render] before loading program: OpenGL error INVALID_ENUM.

when the video loads for the first time
and

[libmpv_render] after creating texture: OpenGL error INVALID_ENUM.

after every switch of shaders

but I can see changes in the image quality regardless
