I need a DirectShow Filter that will act as the avi source for avi files which use proprietary encryption; we shall classify these files as XVP files for now. Each AVI file consists of three parts: 1) A standard avi file encoded in XviD or some other common codec. 2) A second (encrypted) standard avi file encoded in XviD. This file is stored in such a way that a regular avi source/splitter/media player simply ignores it and only displays #1. 3) The decryption key used to encrypt #2 The Filter that you will write will be registered at MERIT_PREFERRED + 255 and will be used on all .avi files on the system. If the file being opened is plain regular .avi file, the task will be passed on to the next highest merit avi source on the system, such as quartz.dll. If the file being opened is an XVP file, the filter will read the key from the XVP file and decrypt the XVP file on the fly (this uses XOR encryption) and then pass it on to the next highest merit avi source (or perhaps to the avi splitter) on the system to do what it normally does. When the filter is installed on the system, part 1 (the non encrypted portion of the XVP file) will simply be ignored and the user will never see it. I will provide the C source code to the encryption software as well as some sample encrypted files to the winning bidder. I presently have a DirectShow Filter avi source and avi splitter, based on the Gabest/guliverkli avi splitter (<[login to view URL]>), which does what needs to be done but it performs the entire avi splitting process internally, which causes conflicts with some applications. Your filter will, on the other hand, leave most of the work to the system default avi splitter, thereby avoiding most problems. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition. A user should be able to begin using the filter by simply executing the [login to view URL] command with the proper parameters. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). Coder may, if he so desires, use code from Gabest's Avi Splitter due to an existing licensing arrangement. This project is a building block in a more complex, but not necessarily more complicated, filter. Upon successful completion, the chosen bidder can expect to have a larger, better paying, project to work on. * * *This broadcast message was sent to all bidders on Thursday Aug 18, 2005 12:06:18 PM: Hello, This project has been replaced by a bigger project that includes components originally described in this bid request. Please see [login to view URL] Thanks ## Platform The filter should work on any build of Windows 98/2000/ME/XP/2003. It is your choice whether to provide different versions for different operating system, or a “one fits all?? version.
