Installing Dolphin 4.0 on Ubuntu 14.04 64 bits

[ciryon]

Hello

I'm trying to install dolphin-emu 4.0 on Ubuntu 14.04 but dependancies are lacking.

The Ubuntu software center tell me libavcodec53 et libavcodec-extra-53 are missing.

I've checked the software center and I have libavcodec54 already installed. I've installed libavcodec54-extra but it replaces libavcodec54 and I hope that will not make the video/audio playin on my system impossible. I have also installed libavcodec-dev and libavcodec-extra but that do not resolve the dependancy issue. Is there a way to install the emulator anyway ?

Thanks team
