After a bit of spelunking in ffmpeg.git and the current releases I have determined that these fixes are present in all ffmpeg versions that are currently in the gentoo tree. I'm not sure when exactly this was backported to ffmpeg 4 so I'll just use the current versions to determine the "fixed" version.
