Google does not "want this fixed", this isn't a bug report from a team using ffmpeg, it's a security analysis from a whitehat security project. I think really if there's all these machine generated meaningless security reports, wasting time with that sounds like a very sensible complaint, but then they should point at that junk as the problem. But for the specific CVE discussed it really looks to me like they are doing everything right: it's a real, default-configuration exploitable issue, they reported it and ffmpeg didn't fix or ask for any extension then it gets publicly disclosed after 90 days per a standard security disclosure policy.
