jamendo.com/en/) and Magnatune (www.magnatune
.com). Both are libraries offering free access to music. Jamendo focuses on free distribution of music
to help musicians grow their audiences. Magnatune helps musicians by licensing their music to those
who would like to use it in commercial ventures (such as films, commercials, Web sites and so on),
while still allowing the musicians to maintain rights to their music.
Exploring Codecs
If you want to play a video or audio file, you need the appropriate codec installed and ready for
use by your media player. A codec is a software-based encoder-decoder used to take existing digital
audio/video data and decode the content. Often, codecs use compression technology to reduce the
size of the data files while retaining the quality of the output.
If you encounter a media file that you know is a working, playable file and you cannot play the file,
you might need to identify and install the proper codec. This often involves installing the proper
playback application, such as DivX 5.0.5 for Linux, which installs the MPEG4 codec for video and
audio playback.
Many codecs are available, so getting the ones you need is usually not an issue. Advances in codec
technology have continued to increase the quality of the encoded content, while reducing file size.
