AVI is a container format - a framework for storing video and audio
streams multiplexed into a single file.
AVI - the framework itself - does not specify the actual format of the
streams. Instead, each AVI file has a header which tells which codecs
should be used for viewing the file. If you don't have suitable codecs
installed in your system, you can't play back the file.
For more information, see:
