Microsoft script decoders

The filter responds to commands in the stream and handles all user input. It creates that is, instantiates a device object for each data type to be decoded in hardware, such as audio and video data types. This filter supports plug-ins that allow expansion for new interfaces. These filters enable playback of video using hardware video ports, and provide support for blending low-bandwidth video streams, such as the closed caption decoder output stream.

Dedicated buses transfer decoded video streams from an MPEG-2 decoder to the display card. Microsoft provides software support for these interfaces by using the DirectDraw hardware abstraction layer HAL with video port extensions VPE to pass video that was decoded in hardware to the video graphics array VGA.

Copyright protection for DVD is provided by encrypting sectors on a disc and then decrypting those sectors before decoding them.

The key exchange sequence is implemented through properties sent to the DVD decoder minidriver's input pins. Hardware-based DVD Decoding. When scanning is in progress, you can press Stop scan at any time. Once the list contains one or more files, you can highlight the one you wish to decrypt, right-click and select Decode , or press the Decode all button at the bottom to decrypt all the files from the list.

Files can be removed from the list by selecting the Remove from list popup menu item. DEC by default. For example, suppose you have a script that looks like this:. Now, the important thing to keep in mind is that the script is simply encoded or obfuscated ; it is definitely not encrypted. What does that mean? That means the encoder will hide your script from most people; however, a truly determined hacker — armed with a knowledge of codes or armed with a utility downloaded from the Internet — could crack the code.

But what about the problem with encoding scripts in an HTA? Or to do it in place overwriting the original :. Thanks DL, for the update! But we do know what does work. All we have to do is change the file extension on the existing file from. Now we can start the Script Encoder using syntax like this:. Are we sure that will work?
