you continue to talk about something completely unrelated to what i
you: take best code
I: for code to be ever in FFmpeg it must either be developed on top
of FFmpeg or it must be rebased/ merged/integrated at some point. Its
better if its developed and tested on top of FFmpeg in the first place
as this is less work and has a lower chance of bugs.
The difference here is the "question" that is awnsered
like in "there are 2 X implementations, which should we use" vs.
"I want to write a X implementation, on top of what codebase should
i do the work"

you really are missunderstanding what i meant
I did not mean to suggest to push
something to main FFmpeg master, i suggested or intended to suggest,
that code be developeed on top of FFmpeg, code generally is developed
by a devloper locally on his box or in his own public repo.

From your point of view its indeed a strawman, and from my point of
view your arguments are a strawman because we just talk about 2
completely different things from the begin.

and if so, how can this be tested ?
knowing this will be usefull to anyone working on the code
