Alrighty, I most definitely do not disagree on either point. Just that
I noticed the CodecState structure some time ago with regards to
MPEG-2 video, and decided to see how its usage with HEVC would be
viewed. The latter point I mostly brought up because a certain other
container decided to ban all kinds of padding when muxing AVC into it,
so I was interested if anyone would prefer something like that with
Matroska as well. My personal opinion is quite similar to madshi's.
I'm human - no debug
