[Solved] Cannot get ffmpeg to use libjxl

I have ffmpeg version 5.1.2, which is supposed to support libjxl. I installed libjxl, and I already had the required library aom. But ffmpeg does not seem to want to use libjxl:

ffmpeg -i --enable-libjxl 20221017_0007.png -c:v libjxl 20221017_0007.jxl

I got the --enable-libjxl option from "man ffmpeg". I also tried rebooting after installing libjxl, but it did not help. What am I missing?

ffmpeg from the Arch repositories is not built with libjxl support,  as such installing libjxl has no effect.  You would need to rebuild ffmpeg with libjxl installed possibly passing the option --enable-libjxl to the  configure script.

On a side note, Image Magick works fine with .jxl files. It can convert to them and display them.

Firefox has a flag to enable them, but it does not work except in Firefox Nightly.
