After more discussing it seems as this may not be enough, because some monitors do not correctly tone-map the black point *down* as intended. I will fix it in a...

There's SVP which is like minterpolate but GPU-accelerated. Other than that I don't know of anything besides the default blend-style interpolation.

If your ffmpeg is built with the corresponding options, you can use the `vf_libplacebo` filter in ffmpeg to apply shaders, including Anime4K, while transcoding.

@lsl330 @aypro it's implemented as a vulkan filter so you have to upload the frame to vulkan first: ``` ffmpeg -i CLIP -init_hw_device vulkan -vf hwupload,libplacebo,hwdownload -vcodec libx264 OUT ```

That's a bit wasteful, it would be much better to `cat` all shaders into the same file and load that. (Though I'll probably fix `vf_libplacebo` to accept multiple shaders soon-ish)...

Hi, if you're using drm with vulkan, libplacebo master now supports sending HDR metadata via Vulkan (on supported drivers). Unfortunately, as far as I can tell, neither ANV nor RADV...

~~I can't reproduce this with the command line options given. Playback is completely smooth for me with those options.~~ Edit: Nvm, my bad. I was testing incorrectly. I can reproduce...

So, what happens here is that, for some reason, the initialization with a different speed causes the mpv frame pts calculations to be 1) out-of-cadence (16 vs 17) with respect...
