Greetings,

I've had
R vf toggle hflip
in my mpv.conf for years but it stopped working some time earlier this year. I used it to flip videos horizontally because many ASMR girls shoot videos with the front facing camera and upload them mirrored which is annoying.
It registers the keystroke and it even says video filter hflip [] but then nothing actually happens. Any idea why this is?

Thanks,
