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?

The library mismatch warning is due to the use of the 'extra' packages/packaging. It's benign & can be ignored — doug, Dec 26 '15 at 14:30
Is there any way to hide the terminal spam without removing the libavcodec-ffmpeg-extra56 package? — Hitechcomputergeek, May 16 '16 at 23:05
I found a way; although this doesn't answer the original question, which uses a bash script, I put for i in ffmpeg ffplay ffprobe ffserver; do alias $i="$i -hide_banner"; done in my .bashrc file. — Hitechcomputergeek, May 16 '16 at 23:43

@Hitechcomputergeek I wish I had seen your comment sooner. Considering this is only a "warning" and can safely be ignored, knowing about that command-line switch is necessary for so ignoring. — Adam Mackler, Nov 12 '17 at 07:42

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

it resolved same issue in ubuntu 16.04 as well. – Ejaz Sep 24 '16 at 03:52

In ubuntu 17.10, this has become libavcodec-extra57 / libavcodec-extra. Amazing that this is still a thing. – Dav Clark Dec 12 '17 at 23:53
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.) – Michael Scheper Aug 19 '18 at 15:41
The comment of @DavClark is still valid for Ubuntu 18.04 – Elvis Dukaj Oct 27 '18 at 10:15

Thanks @DavClark! It works on ubuntu 18.04. I get rid of the warning via sudo apt remove libavcodec-extra57. – hao Jun 18 '19 at 05:43
On Ubuntu 20.04 i get 'Unable to locate package libavcodec-ffmpeg-extra56'
So it seems the version to remove is 58 – Leon D Sep 18 '20 at 20:27
On 20.04 remove libavcodec-extra58. Had to reinstall ffmpeg after removing that. – millerdev Feb 06 '21 at 17:32

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.

You are a star! This worked for me on Mint 20.2, but the earlier answers here didn't. Thank you! – FumbleFingers Nov 06 '21 at 15:29
I confirm this answer is the only one that worked for me on Mint 20.3 as well. Much appreciated! – Adrien Jun 20 '22 at 13:35

On Ubuntu 22.04 I just had to install libavcodec58. It warned that it would remove libavcodec-extra and libavcodec-extra58.

This is because your libs built from ffmpeg source and libs in your system(/usr/lib/ or /usr/local/lib/) are in conflict. So

find . -name "avcodec"

If libavcodec.so.* in /usr/local/lib, /usr/lib/, /usr/lib/x86_64-linux-gnu or /usr/lib/i386-linux-gnu, please replace them with the libs built from ffmpeg source and create soft links.

cp -r /the/path/to/ffmpeg/build/lib/* /usr/local/lib/
sudo ln -s /usr/local/lib/libavcodec.so.59.18.100 /usr/local/lib/libavcodec.so.59

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