- Company: Vodei
Vodei is a file format consisting of a short AVI file with an additional encrypted/obfuscated segment appended to the end.
The AVI portion of the file usually contains a short advertisement for vodei.com encoded with Microsoft RLE. Vodei.com sells software which will decode the additional segment. Although advertised as a "free download", this is adware which will persistently nag the user for payment.
Vodei is not a codec, and after extracting the additional data from the end of the AVI file, simply passes it to the standard Video For Windows interface for decoding. (Since the Vodei software contains no codecs, the Vodei web site recommends that the user install ffdshow.)
It is also believed that Vodei itself is encoding movies in vodei format to entice users into buying vodei just for a few movies.
