From 3c740f2d9f573542313ea64d7ab45fd1669ee511 Mon Sep 17 00:00:00 2001 From: Derek Buitenhuis Date: Thu, 30 Apr 2020 20:06:43 +0100 Subject: avcodec/librav1e: Use the framerate when available for ratecontrol Rav1e currently uses the time base given to it only for ratecontrol... where the inverse is taken and used as a framerate. So, do what we do in other wrappers and use the framerate if we can.
