ffmpeg libvpx ABI mismatch
Closed, ResolvedPublic



Attempting to use the system version of ffmpeg to encode to webm/vp9 target results in the following error:

[libvpx-vp9 @ 0x1a77b80] Failed to initialize encoder: ABI version mismatch


ffmpeg -i source.mp4 -y -an -vcodec libvpx-vp9 -filter:v scale=w=1200:h=480 -crf 2 -b:v 0 output.mp4

Encoding with a 4.4 static-build binary works fine with the above command.

Event Timeline

This should be fixed with a rebuild of ffmpeg. Probably other revdeps of libvpx might be affected by this?

gstreamer-1.0-plugins-good can be skipped, it was already rebuilt.

Didn't rebuild qt5-webengine due to it killing my pc but a quick vp9 test in falkon shows no problems. Didn't rebuild cinelerra-gg due to build failure. I imagine ffmpeg should always have a safety rebuild in future after codec updates.

Just confirming the issue is resolved with today's update.

Thanks everyone!
