some questions
Does this reduce writing speed ? for example when remuxing high
bitrate data like rawvideo ?

does this increase latency as in case of streaming ?
it seemed not from reading the code but iam asking anyway to double

are there any cases where this unreasonably increases memory
consumption ? (thinking of OOM issues here not a few %)
probably not but again asking to be sure, you know the code as
author better ...
