They are, but it's not stdin/stdout pipes that are non-portable with
--input-file, but (a) a fifo socket, (b) binary to create fifo socket
("mkfifo"), and (c) binary to read from fifo socket ("cat").

I think there're some kind of replacements for all of these on windows,
and probably on other more werid platforms that emacs/mpv support, so
there might also be a cross-platform abstraction for these, but maybe
won't help anyway, as mentioned.
