Problems putting MP3 files together

Post by ChrisMadog » Fri Feb 27, 2015 4:31 am

Hi Everyone,

I've had a look around and can't find the answer to this one.
I am in a Community Radio Station and we have a new news feed that arrives via FTP. I want to add and Intro and an Outro to the track to make one track, and play the resultant track to air.

I have three files I want to join together, one after the other.
AIRNewsINTRO.mp3 + airnews.mp3 + AIRNewsOUTRO.mp3 ==> AIRNEWS1.mp3

All files are mp3's at 128kbps sample rate.

The command line I have is:
c:\Zeranoe\bin\ffmpeg.exe -i concat:"AIRNewsINTRO.mp3|airnews.mp3|AIR
NewsOUTRO.mp3" -codec copy AIRNEWS1.mp3

The problem I am having is that the resultant audio track (AIRNEWS1.mp3) shows the correct length at 5m:23s but playing the file it stops after the end of what was the first track (4.55s) :(
Audacity plays it just fine. Windows Media Player has the problem and so does RadioDJ.

Any suggestions please ?

Regards,
Chris
