AngelPotion Definitive MPEG-4

AngelPotion is a hacked version of the Microsoft MPEG-4 V3 codec. The .APL file of this codec includes a packed version of the Microsoft MPEG-4 codec. The AngelPotion DLL manages call between the Microsoft codec and the application. The big problem is that the DLL sometimes modifies the format of the video stream before passing it to the packed Microsoft codec. The impact of this bug can be that Windows Media Player's automatic codec download breaks and that some programs that use DirectX won't be able to decode or play AVI files properly. Because video formats pass through most if not all of the installed codecs during the process of format negotiation, AngelPotion can destroy any video format in any application which can crash your OS.

The AngelPotion format can be decoded with any other version of Microsoft MPEG-4 V3 by changing the two instances of AP41 in the AVI header to the FOURCC of another MPEG-4 V3 codec.

Because this hack is dangerously unstable we suggest that you remove this codec from your computer if you have it installed.
