what version of ubuntu?– fossfreedom ♦Oct 24, 2011 at 20:15

Accepted Answer below works for Ubuntu 32bit only– A CuervoOct 24, 2011 at 21:54
The imm4 codec is a restricted codec - covered by patents, so for some countries you should check if you are covered to run this decoder.
note I've tested this on 11.10
Install the restricted Medibuntu repository:
sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update
Now install mplayer and w32codecs
sudo apt-get install mplayer w32codecs
Now the important part - mplayer is coded to look for the windows DLL VCMIMM4.dll, however, medibuntu installs a lowercase version that mplayer would not recognised out-of-the-box. Thus to fix this, create a VCMIMM4.dll file in the codecs folder.
sudo ln -s /usr/lib/codecs/vcmimm4.dll /usr/lib/codecs/VCMIMM4.dll
Now play your video - e.g.
Will this work on a 64bit install or only 32bit?– A CuervoOct 24, 2011 at 20:54
I've only tested this on 32bit. I think there is "w64codecs" package - give it a try if you have 64bit ubuntu.– fossfreedom ♦Oct 24, 2011 at 20:57
1I can confrim that fossfreedom solution it works on 32bit. It does NOT on 64 bit because w64codecs only contains a handful of realplayer codecs and does not fully replace w32codecs. If you need to play a format only supported by w32codecs, you will need to install w32codecs to /usr/lib32 and use a 32-bit version of mplayer (or an alternate method for running 32-bit apps, such as a chroot or virtualbox) help.ubuntu.com/community/AMD64– A CuervoOct 24, 2011 at 21:42
