Description stephen.smith3141 2021-12-07 11:12:37 UTC

The ebuild for www-client/firefox-95.0, with USE=system-av1 depends on >=media-libs/dav1d-0.9.3, but the latest version of dav1d is currently 0.9.2, so this dependency can never be satisified.

Reproducible: Always

Steps to Reproduce:
emerge =www-client/firefox-95.0 with USE=system-av1

Actual Results:  
The system-av1 USE flag is forced off by Portage. I haven't allowed the compile to proceed, due to how long it takes, but I assume it would build Firefox configured to use its own AV1 decoder.

Expected Results:  
Firefox would be built to use dav1d for AV1 decoding.

At the moment you have to build the internal copy of dav1d, which reads as USE="-system-av1", as mozilla pulled an unreleased snapshot of dav1d into their stable firefox-95.0 release. Hence the package.use.mask kungfu.

That being the case, this isn't a bug, and can be closed. I apologise for the waste of time.
