How do I get rid of ffmpeg `WARNING: library configuration mismatch` message?

Question

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?

Solution 1

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

Solution 2

Adding what worked for me personally (Ubuntu 20.10) because this is one of the first results when searching for this error, and it's been making me mad for the past couple days:

sudo apt install --reinstall libavcodec58 libavdevice58 libavfilter7 libavformat58 libavresample4 libavutil56 libpostproc55 libswresample3 libswscale5

I didn't even need to reinstall FFmpeg.

it resolved same issue in ubuntu 16.04 as well.

In ubuntu 17.10, this has become libavcodec-extra57 / libavcodec-extra. Amazing that this is still a thing.

[Michael Scheper]

At the risk of upsetting the Ubuntu Police: This also worked on Mint 18. (Great answer, BTW—The quick fix, the explanation, and the reference link. Thank you.)

[Elvis Dukaj]

The comment of @DavClark is still valid for Ubuntu 18.04

[hao]

Thanks @DavClark! It works on ubuntu 18.04. I get rid of the warning via sudo apt remove libavcodec-extra57.

[Leon D]

On Ubuntu 20.04 i get 'Unable to locate package libavcodec-ffmpeg-extra56' So it seems the version to remove is 58

[millerdev]

On 20.04 remove libavcodec-extra58. Had to reinstall ffmpeg after removing that.

[FumbleFingers]

You are a star! This worked for me on Mint 20.2, but the earlier answers here didn't. Thank you!

[Admin]

I confirm this answer is the only one that worked for me on Mint 20.3 as well. Much appreciated!
