This topic describes how to use DirectShow to play media files that are protected with Windows Media Digital Rights Management (DRM). DRM Concepts Protecting a media file with Windows Media DRM involves two distinct steps:. The content provider packages the file—that is, encrypts the file and attaches licensing information to the ASF file header. The licensing information includes a URL where the client can obtain the license. The client application acquires a license for the content.

Packaging happens before the file is distributed. License acquisition occurs when the user tries to play or copy the file. License acquisition may be either silent or non-silent. Silent acquisition does not require any interaction with the user. Non-silent acquisition requires the application to open a browser window and display a web page to the user. At that point, the user might need to provide some kind of information to the content provider.

However, both types of license acquisition require the client to submit an HTTP request to a license server. DRM Versions Several versions of Windows Media DRM exist.

How to unlock or retrieve WMV? Small wmv and mov files which are to. I just stumble upon this tutorial about how to unlock drm from protected wmv files. Upload the protected WMV file, or files, to the Tunebite program. The files will appear in a list in Tunebite's open window. Select WMV as the conversion file of choice under 'Convert Video File To'. Learn how to remove DRM from WMV with the best DRM WMV removal, which can crack DRM protection from WMV files and convert them to any video formats.

From the perspective of a client application, they can be grouped into two categories: DRM version 1, and DRM version 7 or later. (The second category includes DRM versions 9 and 10, as well as version 7.) The reason for categorizing DRM versions this way is that version 1 licenses are handled somewhat differently than version 7 or later licenses. In this documentation, the term version 7 license means version 7 or later. It is also important to distinguish the DRM packaging from the DRM license. If the file is packaged using Windows Media Rights Manager version 7 or later, the DRM header can contain a version 1 license URL in addition to the version 7 license URL. The version 1 license URL enables older players that do not support version 7 to obtain a license for the content. However, the converse is not true, so a file with version 1 packaging cannot have a version 7 license URL.

Application Security Level To play DRM-protected files, the client application must be linked to a static library that is provided in binary form by Microsoft. This library, which uniquely identifies the application, is sometimes called the stub library. The stub library has an assigned security level, the value of which is determined by the license agreement that you signed when you obtained the stub library. The content provider sets a minimum security level needed to acquire the license.

If the security level of your stub library is less than the minimum security level required by the license server, the application cannot obtain the license. Individualization To increase security, an application may update the DRM components on the client's computer. This update, called individualization, differentiates the user's copy of the application from all other copies of the same application.

The DRM header of a protected file may specify may specify a minimum individualization level. (For more information, see the documentation for WMRMHeader.IndividualizedVersion in the Windows Media Rights Manager SDK.) Because the Microsoft Individualization Service handles information from the user, you must display the Microsoft privacy policy or provide a link to that page at the Microsoft website before your application individualizes:. Provide the Software Certificate To enable the application to use the DRM license, the application must provide a software certificate or key to the Filter Graph Manager. This key is contained in a static library that is individualized for the application. For information about obtaining the individualized library, see in the Windows Media Format SDK documentation. To provide the software key, perform the following steps:.

Link to the static library. Implement the IServiceProvider interface. Query the Filter Graph Manager for the interface.

Call with a pointer to your implementation of IServiceProvider. The Filter Graph Manager will call IServiceProvider::QueryService, specifying IIDIWMReader for the service identifier. In your implementation of QueryService, call to create the software key. The following code shows how to implement the QueryService method. Done: return hr; Building the Playback Graph To play a DRM-protected ASF file, perform the following steps:. Create the and use the interface to register for graph events. Call to create a new instance of the filter.

Call to add the filter to the filter graph. Query the filter for the interface. Call with the URL of the file. Handle events. On the first event, query the filter for the IServiceProvider interface. Call IServiceProvider::QueryService to get a pointer to the interface. Call to render the output pins of the filter.

Feedback im guessing that you are trying to get films or porn!! And the files you get areally quite small in comparison to the mpegs!! Only about 2 or 3 meg or so!! You need to get the licence which when they are purchased they send then to your e mail!! Just use avi or mpeg files if you are downloading!! I use lime wire, bear share and variouse torrent sites, just see which is faster and get that one!!

Small wmv and mov files which are to small to be real need licences!! Say a 2 hour film of any decent quality will be 400 meg + anything less and it will be shit!!
