MP3 contcat error => Application provided invalid, non monotonically increasing dts to muxer in stream 0

[Riles]

Hello all,

I have a problem to merge two mp3.

The command i use to merge two mp3 files is:

ffmpeg.exe -y -f concat -safe 0 -i list.txt -c copy final.mp3

The file final.mp3 is unreadable and inside the console i can see in a loop the following error message:

Application provided invalid, non monotonically increasing dts to muxer in stream 0

Resources are:

1.mp3 => ​http://dl.free.fr/fLNv2uVQX
2.mp3 => ​http://dl.free.fr/n7vveNoCO
list.txt => ​http://dl.free.fr/smu2sIBBl
final.mp3 => ​http://dl.free.fr/nVIPO6zw9

This files are available only 30 days from now.

Thanks a lot for your help.

Regards,
Riles
