Slow seek performance #22

Works great but can anything be done to improve the seek performance. Running a 4090 + i7 12700k. Are the buffers to be filled the cause of pause on seek? If so, can they be reduced.

I wrote a plugin to help with this, but it's still a work in progress and doesn't work perfectly yet. This Lua script disables upscaling with the model during seek and then restores upscaling when you're done seeking. Download this file:

and place it at this location: mpv-upscale-2x_animejanai\portable_config\scripts

Let me know how it works for you.

It does fix the seek time with some downsides. There is a tiny stutter when the upscale profile kicks in along with the noticeable sharpness change of profile switch. The vapoursynth filter osd msg on the top left is better hidden. If I send multiple seeks at once,the upscaling profile fails to apply some times.
