This commit has no known use case ATM as there are no unsupported video codecs in flv and could
theoretically be use to generate broken files allthough that would be not entirely easy as
tags/codecs still get sanity checked

This reverts commit 76f4b117.

This allows stream copying video codecs before they are explicitly
supported. The same feature was in the past useful for audio codecs
in flv

This basically switches to the implementation from f6f7d150
which seems faster

previously they where only updated when decoding started and would thus have
been inconsistent for a longer period of time leaving more chances for
problems
