I am using Ubuntu 9.10. Recently I had convert my pendrive from FAT32 to NTFS format to save mkv files. Then when I insert and play it in Ubuntu it doesn't play. The following error occurs:

The required software to play this file is not installed. The playback software MPEG-4 AAC decoder is required.

How can I get, install and play it on Ubuntu 9.10?

Flagged off-topic because 9.10 was EOL 1 year before this question was asked. – kraxor Jun 9 '14 at 17:49

You need to install the codec to allow your video program to understand MPEG-4 AAC audio. The Ubuntu site doesn't have the 9.10 Karmic packages listed anymore, but it is probably the same as in 10.04 Lucid.

So, you need to install the faad codec and tools which are in the universe repository.

You could try using a terminal program and typing

sudo apt-get install faad libfaad2

If that doesn't help, let us know what video program you are using.

For the ubuntu movie player, this might help

Or this is for VLC,
