[FFmpeg-user] Reidrecting showinfo output

[Tim Nicholson]

I find the showinfo output useful for various diagnostic tasks, but 
would find it more so if I could redirect its output to file.

I have tried the following:-

ffmpeg -i infile -vf showinfo -f mp4 -an -c:v copy -y /dev/null 2> info.txt

with variations on 1>, 2> &> | tee etc

However I either get nothing or just the usual ffmpeg header info, and 
when nothing goes to file I get no console output either.

Is there a way of achieving this?
