The more codecs are supported in different browsers, the less interoperability
you get. It's not good for the Web to want to introduce more variety on
supported file formats - the target should be one, not all.

> BTW, which codecs can FLV contain?

It's a container like Quicktime, Ogg, Matroska, and MP4 - they can all support
all codecs, even though you would not typically find all codecs in all formats.
But as I said: the answer to this question doesn't matter - it's not desirable
to support more codecs/containers.
