To me its okay to “demand” from a for profit company (eg google) to fix an issue fast. Because they have ressources. But to “demand” that an oss project fix something with a certain (possibly tight) timeframe.. well I’m sure you better than me, that that’s not who volunteering works
The X days is a concession to the developers that the public disclosure will be delayed to give them an opportunity to address the issue.
Why is Google deliberately running an AI process to find these bugs if they're just going to dump them all on the FFmpeg team to fix?
They have the option to pay someone to fix them.
They also have the option to not spend resources finding the bugs in the first place.
If they think these are so damn important to find that it's worth devoting those resources to, then they can damn well pay for fixing them too.
Or they can shut the hell up and let FFmpeg do its thing in the way that has kept it one of the https://xkcd.com/2347/ pieces of everyone's infrastructure for over 2 decades.
How many people are actively looking for bugs? Google, and then the other guys that don't share their findings, but perhaps sell them to the highest bidder. Seems like Google is doing some good work by just picking big, popular open source projects and seeing if they have bugs, even if they don't intend to fix them. And I doubt Google was actually using the Lucas Arts video format their latest findings were about.
However, in my mind the discussion whether Google should be developing FFmpeg (beyond the codec support mentioned elsewhere in the thread) or other OSS projects is completely separate from whether they should be finding bugs in them. I believe most everyone would agree they should. They are helping OSS in other ways though, e.g. https://itsfoss.gitlab.io/post/google-sponsors-1-million-to-... .
