Subject: ffmpeg: add a (possible) build race fix
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9dbd2141b52b24421927d64cd74ec43f6085c4f2;p=thirdparty%2Fopenembedded%2Fopenembedded-core.git

ffmpeg: add a (possible) build race fix

There's been an intermittent build fail that looks like a race:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=16000

While I can't say for sure if this is fixing the issue,
there's no harm in adding a backport that rearranges the
faulty code, and someone can then try to add a real fix on top
of it. Or the race goes away and we're good.
