I see we are doing this in a lot of encoders, but this seems just bad to
While it reduces latency, it also reduces performance in some use-cases.
In addition, it is just silly code duplication to have this inside
(almost) every single muxer.
Extracting it in some way and possibly making it configurable seems
like it would be a good thing to do long-term.
