[Solved] ffmpeg Failed to initialize encoder: ABI version mismatch

ffmpeg is not able to produce a webm file using libvpx.  Here's what I see:

It has no problem generating a mkv, mov, mp4 or any other type of output.

Here's what I think are the related packages that are installed

$ pacman -Q | grep -E '(ffmpeg|libvpx|gst)'
clutter-gst 3.0.27-3
ffmpeg 2:4.3.2-3
gst-editing-services 1.18.4-1

lib32-libvpx1.3 1.3.0-2
libvpx 1.10.0-1
libvpx1.3 1.3.0-3

I've tried reinstalling all of the above, but no luck.  Any suggestions on how to debug further?

Re: [Solved] ffmpeg Failed to initialize encoder: ABI version mismatch

ffmpeg might have to be recompiled with the new libvpx.

$ CUTF pacman -Si ffmpeg libvpx | grep -e Name -e Date
Name            : ffmpeg
Build Date      : 2021-03-18 W11-4 11:48:43 +0100
Name            : libvpx
Build Date      : 2021-03-25 W12-4 08:41:05 +0100

Re: [Solved] ffmpeg Failed to initialize encoder: ABI version mismatch

Sounds like it should be reported to the ffmpeg packager, then?  I confirmed downgrading libvpx to 1.9 from August 2020 works.

Thank you!

Re: [Solved] ffmpeg Failed to initialize encoder: ABI version mismatch

I'm still getting this error: "ABI version mismatch"

Did anybody report this anywhere? If so I would love a link to the issue so I can follow it.

Re: [Solved] ffmpeg Failed to initialize encoder: ABI version mismatch

This was fixed long ago. What version of the ffmpeg package do you have?
