Given that libaom 3.2.0 just passed the NEW queue, there's really no benefit
on keeping version 1.0.0.errata1.avif and handling related ABI breaks. In
Debian Sid, I will revert to the old libaom version (the same as in Debian
Testing) and initiate a formal transition from libaom 1.x to libaom 3.x.

Thanks for the report and let me know if there are any further issues (e.g.,
issues related to transition).

Regards,
Boyuan Yang

Bug#997806: aom: possible ABI breakage; causes ffmpeg autopkgtests failures

[Sebastian Ramacher]

Source: aom
Version: 1.0.0-errata1.avif-1
Severity: serious
X-Debbugs-Cc: sramac...@debian.org

From ffmpeg's autopkgtest:
| Test 31:

See
https://ci.debian.net/data/autopkgtest/testing/amd64/f/ffmpeg/16162728/log.gz

Combined with the changes in aom's headers, this looks like ABI breakage
to me.
