i dont know,
you know these protocols better than i do so you better
know if its needed or if a simpler system like failing with an error
code and reconnecting with un/pw set through AVOptions but not
vissible on  the command line could be used.
one way could be to read the options value from a file/pipe and only
specify the file/pipe name on the command line
(but wait with implementing that to give others time to comment first)

There are several potential places this could be implemented in
The code needing a un/pw could perform the fileopen and extract the
un/pw,

the common command line handling for ffplay/ffmpeg could read from
a file and set the AVOption accordingly, other applications would
then need a similar change

what do people prefer, in case this path is choosen ?

Thanks

there is nothing more to fear from them, then he is always stirring up
some war or other, in order that the people may require a leader. -- Plato
