I am giving the input file in the command line like this:

ffmpeg -i catch.flv.

The information about the file such as resolution, frame rate, bit rate etc is displayed in the terminal. I want this information to be stored as a (.txt) file. I have tried ffmpeg -i catch.flv > catch.txt. The .txt file was created successfully but the information is not stored in it. Could someone please help?

This question came from our site for professional and enthusiast programmers.

ffmpeg prints that information to the standard error, not to the standard output; to capture it, you should use e.g.

ffmpeg -i catch.flv 2> catch.txt

(you can have a look here to learn more about standard streams redirection)
