This is a deficiency in ./mach vendor . Please review the affected files before committing.

We're going to continue processing the update; but we may fail because we couldn't handle these files. If we do succeed, you may want to add these files to the 'exclude' key in the moz.yaml file, so they are excluded from the source tree and ignored in the future.

It looks like we experienced one or more build failures when trying to apply this
update. You will need to apply this update manually; you can replicate the patch
locally with ./mach vendor media/libdav1d/moz.yaml. I'm going to abandon the Phabricator patch and
let you submit a new one.

If the build failure wasn't caused by a library change, and was instead caused by
something structural in the build system please let my maintainers know in
Slack:#secinf.

I do my best to automatically add new files to the build, but some moz.build files
are complicated and you may need to fix them manually.
