neroaac -he -q 0.7 -if 01.wav -of test.mp4
and the error message and progress message show correctly.
then i added "2> temp.txt", the output doesn't work. after i press ctrl-c, there's only a "^C" staying in the temp.txt.
i'd hope to write a simple command line wrapper for it so i'd like to know how to redirect the message out. (of cuz i'll use pipe
)
