Creo que este es un problema conocido cuando se trata de la Multi-Architecturegestión de paquetes. apt-getpresenta la solución preferida para mantener el arco instalado actual de los mismos paquetes, que no es lo que desea en algunos casos.
En este caso, la mejor solución era reemplazar esos :i386(libavcodec54 o libavcodec-extra-54, libavformat54, ... otros paquetes del árbol de dependencias) con los :amd64paquetes correspondientes .
AFAIK, la solución más fácil es el uso aptitudeque proporciona todas las demás soluciones posibles y le permite seleccionar lo que prefiera.
Probado en un VirtualBox (Ubuntu 14.04). Lo instalé:
sudo apt-get install gstreamer1.0-libav:i386 libavcodec54:i386 libavformat54:i386 \
libopus0:i386
Intentar instalar gstreamer1.0-libav genera el mismo mensaje de error:
# apt-get install gstreamer1.0-libav
