ffmpeg relocation error

  • 772

I've tried to install FFmpeg from the default repository on 18.04. 

ffmpeg: relocation error: /usr/lib/x86_64-linux-gnu/libswresample.so.2:   
symbol av_calloc version LIBAVUTIL_55 not defined in file 
libavutil.so.55 with link time reference

I believe I may have broken the shared libraries in the past when I tried to compile ffmpeg from source and then gave up.

Seeing this file in question /usr/lib/x86_64-linux-gnu/libswresample.so.2 was provided by the package libswresample2

$ dpkg-query -L libswresample2
/.
/usr
/usr/lib
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/libswresample.so.2.9.100
/usr/share
/usr/share/doc
/usr/share/doc/libswresample2
/usr/share/doc/libswresample2/copyright
/usr/share/lintian
/usr/share/lintian/overrides
/usr/share/lintian/overrides/libswresample2
/usr/lib/x86_64-linux-gnu/libswresample.so.2
/usr/share/doc/libswresample2/changelog.Debian.gz

I tried to reinstall ffmpeg, libswresample-dev, libswresample2, libavutil55, and libavutil-dev and I'm still receiving the same error. I'm trying to avoid compiling ffmpeg from source again if possible.

  1. You can always download static builds and use them. This will solve your problem. However, I would recommend you to fix this dependency issue so you can use the latest ffmpeg version after apt-get update.
