ffmpeg trim .mp3 - output length forced to 2 seconds - ffmpeg
I have just downloaded the latest version of ffmpeg and I am trying to trim the first 14 and the last 6 seconds from a 40 seconds .mp3 file.
The problem I have is that doesn't matter what -t X I use, the output is always only 2 seconds in length. It's my first using ffmpeg but it seems like something is forcing it to limit the output to 2 seconds.
I tried a lot of commands including
ffmpeg -ss 00:00:14.358 -i input.mp3 -ab 32k -t 00:00:20.04 -c:a copy output.mp3 -y
ffmpeg -ss 14 -i input.mp3 -ab 32k -t 20 -c:a copy output.mp3 -y
ffmpeg -ss 14 -i input.mp3 -t 20 -acodec copy output.mp3 -y
ffmpeg -ss 14 -i input.mp3 -acodec copy output.mp3 -y
ffmpeg -ss 14 -t 20 -i input.mp3 output.mp3
ffmpeg -ss 14 -i input.mp3 -t 20 output.mp3
but the result is almost always a 2 sec mp3 file.
Now I'm out of ideas.
As requested this is the output from the console:

What am I doing wrong ?
The following work for me. Here is first 14 seconds:
ffmpeg -i input.mp3 -ab 32k -c:a copy -t 00:00:14 output.mp3 -y
Last 4 seconds (start from 6 seconds before end -> 40-6=34):
ffmpeg -ss 00:00:34 -i input.mp3 -ab 32k -c:a copy -t 00:00:06 output.mp3 -y

How to deal with "[asf XX] too long payload" message in ffmpeg?
I am trying to cut a small section of a video using the following sentence: ffmpeg.exe -i video.wmv -ss 00:20:02 -to 00:20:09 -crf 22 "C:\test.mp4" -y However, ffmpeg hangs showing messages like: [asf # 03327b00] too long payload 0kB time=00:00:00.00 bitrate=N/A speed= 0x Last message repeated 352 times [asf # 03327b00] too long payload 0kB time=00:00:00.00 bitrate=N/A speed= 0x Last message repeated 331 times I have waited for more than 30 minutes and ffmpeg did not finish the cutting.

I figured it out! If you have the same problem just go to youtube stream now / encoder setup / stream name/key, push the reveal button and then the reset button to get a new stream name/key string. Use the new key!
FFMpeg is dropping video track when clipping an mpg video
