It is probably possible for some cases and it would be a good idea
either way, but iam not sure theres a volunteer to do this.

btw, I think the most suitable and flexible format for this is the
ffprobe one requiring the ffprobe demuxer patch
It would allow all kinds of transformations to be done with a minimum
of work to create more minimal test cases.

Theres no way i can really say how hundreads of tickets behave if
they are turned from encoding into stream copy. My guess is that for
many that would work for some it would probably not work

Many things microsoft did are stupid, but not doing something just because
microsoft did it is even more stupid. If everything ms did were stupid they
would be bankrupt already.
