How can I play mp4 files from a USB live iso of Ubuntu 11.04? I can mount my external hard drive, but totem wouldn't allow me to play my mp4 files. Trying to find the ubuntu restricted packages with "apt-cache search restricted" gives me nothing back.
I imagine you'd have to first change your sources lists first. Medibuntu is how I used to do it.
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
Once you've done this you should be able to install
You can install these packages from a live USB session and keep them in a reserved space if you had set up your USB-drive for this feature.
