 Why do you think so?
 (Especially without investigating.)

 Or do you mean that whenever FFmpeg does not support a specific sample of
 a supported file (or codec) format, the file is ''at fault''? I guess this
 could be said but since we like samples, this is not a particular useful
 approach if we want to improve FFmpeg.

 from every broken encoder.

 This is what we do (for more than a decade) and I believe there are
 indications that we are very successful with this approach, despite the
 ''maintenance burden, code curn, log/mailing list/bug tracker noise''
 (that I do not agree with).
 I agree that the possible security issues were less important in the past
 (and are more important now) but imo, that shouldn't stop us from trying
 to fix issues and implement new features without introducing new security
