As much as I hate to be on Google's side I think they're doing a reasonable thing here. Valid bug reports are valuable contributions on their own, and disclosing security issues is standard practice. Not disclosing them doesn't help anyone. Security through obscurity is not security. If neither FFMPEG nor Google dedicate resources to fixing the issue in 90 days, making it public at least ensures that it gets visibili…
I promise they are spending more on extra compute for resiliency and redundancy for FFMPEG issues than it would cost for a single SWE to just write a fix and then shepherd through the FFmpeg approval process.
