Anyone figure me out, thanks

[Carl Eugen Hoyos]

Please provide the complete, uncut console output for the failing command line and please provide the sample.

The file is too large about 410M, this is the link ​http://116.204.127.26/test/iv41.avi.

When I run the cmd "ffmpeg -i iv41.avi -y -f image2 -ss 00:00:10 -s 360X240 -t 1 -vframes 1 iv41.jpg > o.txt", the screen scrolls very fast, I can not catche the first screen.

Thanks for your help.

I add one parameter to run the command, then get the uncut console output.
