[FFmpeg-user] remove audio in the latest version windows 20180429-19c3df0-win64-static

[juan carlos rebate]

Since the last version something must have changed because it doesn't work
as it should, or at least not as it always has.
I have a file with 2 audio tracks and I want to remove one of them,the file
has three tracks, one video track and two audio tracks,in previous versions
I usually do the following:
ffmpeg-i imput.avi -map 0:0 -vcodec copy -map 0:1 -acodec copy -map 0:2 -an
aoutput.avi
instead of removing only one, both are removed,but the wiki indicates the
steps that I have described,Could someone tell me how to do this correctly
for the new version?
