Have a try Julia v1.5.1 for arm32bit

This method might help you.

install ffmpeg via apt and copy to path/to/FFMPEG_jll

https://github.com/Julia-Embedded/jlcross/issues/21

OK great, this looks promising. I’m not sure I’m doing it right though… I ran

cp /usr/lib/arm-linux-gnueabihf/libx265.so.165 /home/pi/.julia/artifacts/4aa3a4154795fad4cba5fdb55d9be30840315788/lib

but still get the same error:
