This allows ending up with a normal, non-fragmented file when

is finished properly.)
This results in a file where the mdat atom contains (and hides)
all the moof atoms that were part of the fragmented file structure
initially.

v2: Made the flag implicitly set FF_MOV_FLAG_FRAGMENT (as it makes
no sense without it).
Updated the description of the flag to "Write a fragmented file that
is converted to non-fragmented at the end".
Kept the flag named "hide_fragments", but I'm also pondering if we
maybe should go for a name like "hybrid_fragmented" or so, as a
better description of _what_ it produces, as opposed to _how_ it
does things. (One could also consider "hybrid_mp4", but even if mp4
is the main thing, the same also goes for mov and a bunch of other
related formats.)
I'd otherwise want to push this, but I'm not entirely satisfied with
the option name quite yet. I'm pondering if we should call it
"hybrid_fragmented" - any opinions, Dennis or Timo?
How about `resilient_mode` or `recoverable`?
I agree that the how is secondary.
Those are good suggestions as well - but I think I prefer
"hybrid_fragmented" still.
In theory, I guess one could implement resilient writing in a number
of different ways, whereas the hybrid fragmented/non-fragmented only
is one.
So with a couple other voices agreeing with the name
"hybrid_fragmented", I'll post a new patch with the option in that
form - hopefully you don't object to it.
The term hybrid is not applicable here. The fragmented state is
transient during writing and contingent in the finished artifact
depending on how the writing process concluded.
Hybrid implies both modes available e.g.. a hybrid vehicle can use both
types of energy sources. The artifact here will be one _or_ the other.
