MPD symbol lookup error problem since update (~2 weeks ago)

Hello !

I'm unable to start mpd since a few weeks.

[l'pc@archmobile etc]$ sudo mpd --verbose
mpd: symbol lookup error: /usr/lib/libavcodec.so.52: undefined symbol: vpx_codec_destroy

I've  tried different versions of mpd and of ffmpeg (which provides libavcodec) to no avail...

Output of ls -l /usr/lib/libavcodec*

-rw-r--r-- 1 root root 6123578  5 nov 10:24 /usr/lib/libavcodec.a
lrwxrwxrwx 1 root root      21  5 nov 10:24 /usr/lib/libavcodec.so -> libavcodec.so.52.94.3
lrwxrwxrwx 1 root root      21  5 nov 10:24 /usr/lib/libavcodec.so.52 -> libavcodec.so.52.94.3
-rwxr-xr-x 1 root root 5314696  5 nov 10:24 /usr/lib/libavcodec.so.52.94.3

There is nothing relevant in the mpd logs.
I'm using mpd 0.15.15-1 and ffmpeg 25679-1

And I just noticed that VLC also can't read videos but can read audio files.
VLC error with a video :

[0xb3203694] main decoder error: no suitable decoder module for fourcc `mp4v'. VLC probably does not support this sound or video format.

It is maybe related ?

How to fix this ?

Edit : forgot to mention package versions...
Edit 2 : Added the VLC problem

Re: MPD symbol lookup error problem since update (~2 weeks ago)

You need to recompile some custom package, can you post the output of:

pacman -Qo /usr/lib/libavcodec.so.52

and

pacman -Qo /usr/bin/mpd

Here are the outputs you asked for:

[l'pc@archmobile etc]$ pacman -Qo /usr/lib/libavcodec.so.52
/usr/lib/libavcodec.so.52 appartient à ffmpeg 25679-1

and

[l'pc@archmobile etc]$ pacman -Qo /usr/bin/mpd
/usr/bin/mpd appartient à mpd 0.15.15-1

I hope I won't need to compile something, because I've never done it...
Guess I'll learn something today !

Thank you for your rapid answer.

Ps: sorry I forgot to mention the versions...
