I can't seem to repro on 1.70.0-nightly (f63ccaf25 2023-03-06), arch as well. Can you try installing through my AUR package?

Closing this unless I get more info here

I ran into this as well on Ubuntu Mate (jammy), same error message. The version being sourced is probably the one I compiled from source:

Although I only did that to compile OBS and I mostly use the one that comes with Snap, and I have no idea how to pass that to cargo, hehe.

EDIT: I came here from a google search and thought this was the ffmpeg-next github repo, but since it wasn't mentioned, this error happens while building the ffmpeg-next-sys dependency.

It seems FFMPEG_DIR env var can be used to use a custom ffmpeg
