Backport the commit from master instead:
https://git.openembedded.org/meta-openembedded/commit/?id=c7b77535e0b08e8c89f41fa0508d3b275c95ab80

in this case it's the same, but using the same commit message and author will better indicate that it's straight cherry-pick from newer branch.

ffmpeg isn't enabled by default. Fixes yocto-layer-check error:

ERROR: Nothing PROVIDES 'ffmpeg' (but /home/builder/src/base/meta-openembedded/meta-gnome/recipes-gnome/tracker/tracker-miners_2.3.3.bb DEPENDS on or otherwise requires it)
ffmpeg was skipped: because it has a restricted license 'commercial'. Which is not whitelisted in LICENSE_FLAGS_WHITELIST
ERROR: Required build target 'meta-world-pkgdata' has no buildable providers.
Missing or unbuildable dependency chain was: ['meta-world-pkgdata', 'tracker-miners', 'ffmpeg']

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.
