my mpv config

screenshot-format = "jxl";
screenshot-avif-pixfmt = "yuv420p10le";
# screenshot_$FILENAME_$YEAR-$MONTH-$DAY-$HOURS-$MINUTES-$SECONDS_$PLAYBACKTIME_INCL_MILLISECONDS;
screenshot-template = "%f_%tY-%tm-%td-%tH-%tM-%tS_%P";
screenshot-dir = "~/Pictures/Screenshots/mpv";
screenshot-tag-colorspace = "no";
screenshot-high-bit-depth = "yes";
autofit = "50%";
audio-channels = "stereo";
audio-normalize-downmix = "yes";
vo = "gpu-next";
hwdec = "auto";
#tone-mapping=clip;
af = "lavfi=[loudnorm=I=-16]";
screenshot-sw = "yes";

Additional context

I've using different decoders for avif but none of them work. Setting screenshot-avif-encoder to libsvtav1 takes the screenshot without error but the file is corrupted and cannot be opened.

330056 might solve your webp woes

but if you want jxl you'll probably need to override mpv to use ffmpeg-full

Thanks, I didn't know about that solution. I don't mind at all using ffmpeg-full and testing it just now, all the screenshot formats work, including JXL, AVIF, and WebP.

Reading through the topic you linked made me wonder: why is size considered so important? Shouldn't the program working without throwing errors be more important?
