Convert asf format videos using ffmpeg and ffprobe in Linux

Basic conversion would be as below;

ffmpeg -i input.asf output.avi

If we wanted to change the resolution, we would first do;

ffprobe -v error -select_streams v:0 -show_entries stream=width,height -of csv=s=x:p=0 input.asf

which would show us the original resolution, we could then set the resolution of the output as below;

ffmpeg -i input.asf -vf scale=704x506 output.avi
