I hate this kind of blitzkrieg, that tries to establish new Status Quo.
I'm afraid you just turn a struggle into full scale war.

Actually this is how our struggle with Diego started. He ignored the
discussion and made highly disputable commit. Then things escalated.
Do you want the same?

What are we going to use for wav tags for audio formats that doesn't
have official one?
I have asked this quiestion about 5 times already.

That would be better to be named "SourceStreamTag" .

I'd also like to have "SourceEncoder" that contains the name and
version of the encoder.

BTW, why  chapter_id/start/len are mandatory fields in the info packet
and not entries like all the rest?
