re: "can't you be more optimistic"

Stephan, computer security is a deeply depressing subject. There truly are no silver bullets. The best one can hope for is diligent application of best practices: code auditing, fuzzing, static and dynamic analysis, logging of crashes in field, monkeybots, compiler and OS level mitigations (e.g. address space randomization), sandboxing, and eternal vigilance.

The Firefox people think it would a large maintenance and security issue to support video codecs other than Theora however Chrome seems set to do this with ffmpeg and H.264

How does Google intend to manage security issues arising in ffmpeg?

Thanks for writing this up.
