I have been using avconv without issue, however since upgrading to 15.10 and switching to ffmpeg, I have a library configuration mismatch warning in my script output.

This is my command to rip CDs for my iPod and Fiio X5 Mk2.

#!/bin/bash



cdparanoia -Bv

for f in ./*.wav; do avconv -i "$f" -acodec alac "${f%.*}.m4a"; done

eject

ls

When I replaced avconv with ffmpeg I now see WARNING: library configuration mismatch in the middle of the output:

Checking other sites suggests I have installed ffmpeg on an early version of Ubuntu where avconv was the default, but this wasn't the case here.

Can anyone suggest a resolution for me?

To fix this remove the following package:

sudo apt remove libavcodec-ffmpeg-extra56

Apt will remove the package and replace it with libavcodec-ffmpeg56 resulting in ffmpeg no longer output a warning message.

For details on libavcodec-ffmpeg-extra56 package and why it is likely no needed, see: https://askubuntu.com/a/847566/8570

On Ubuntu 18.04:

sudo apt remove libavcodec-extra57
