Some wmv formats contain DRM, and DRM technology is digital rights management technology.
Third-party players cannot play some videos in WMV format. They must be played through windows media player and play online, and cannot be played offline. Because you need to connect to the network to verify the DRM digital signature, you can only play it after obtaining a license.
cardinal symptom
It turns out that many videos are difficult to download. Since the use of audio-visual detectives, all problems have been solved.
Now I have encountered the problem that after downloading the video in WMV format, I need a license when playing it, as shown in the following figure:
1. Play it with Windows Media Player, prompting that you need to download the license;
2. Play it with Classic media player, prompting that it cannot be rendered;
3. After downloading the video file, it is found that its "attribute" is "protected content"; The status bar is displayed as protected: Yes;
4. You can't use video editing software (such as Windows Movie Maker) to edit it.
The biggest drawback of this wmv video is:
1, which is not conducive to communication (some disc engraving is prohibited);
2, inconvenient to watch (some require that you download the license every time you play it);
3. The license cannot be played after it expires;
It can't be treated and reused.
And these are probably the real purpose of the producer to encrypt it.
How to play such a protected file?
It is a normal way to watch this kind of software by connecting to the Internet and obtaining a signature license.
If you can't get online and want to watch offline, use software to remove the license verification information from wmv.
In addition, there is another way to record the video you see with software and then make it into a video format.
Collect and sort out some cracking methods, which are explained as follows:
Description:
1, the kid and sid in wmv are not visible with FairUse4WM, please use drm2wmv tool.
When restoring a license using FairUse4WM,
Appeared: windows error 80030002 occurred when looking for kid in v9store.
FairUse4WM can't find KID and SID, so you can use drm2wmv tool.
2. Whether using DRMGUI or FairUse4WM to crack license restrictions, there is the same premise: you must have at least one license that can be used normally. Similar to Phoenix Satellite TV, wmv videos that need a license to play must be downloaded with an account, and neither software can do anything about it.
First, how to use FairUse4WM
Some broadcast wmv, prompting to upgrade DRM components, and you can directly click the prompt to upgrade.
You can also click on Microsoft's next official website below to complete the upgrade.
You need to obtain an activated license file, log in, click the upgrade button, and a window will pop up later, showing the obtained license (or prompting you to complete the upgrade). Just click "Yes". Reboot to complete the installation.
The network is blocked, try several times.
1. Download and install the Chinese version of FairUse4WM;
or
Download FairUse4WM() 1.3 Chinese version. This version contains rogue software. When installing, be careful not to go to the next step all the time. Just remember to uncheck the box of rogue software. Run after installation, and click the Restore License button. If there is no prompt "IBX component doesn't seem to exist", you can skip it directly.
2. Run FairUse4WM for the first time, prompting "No license is loaded", and at least one activated license file is required;
(this is different from DRMGUI)
3. Press "Restore License", confirm twice, and then select a licensed windows media file;
4. The program automatically runs Windows Media Player, and then shows that 1 licenses are loaded. Click "Next" at this time;
5. Add files (to be cracked) and select the output path;
6. Press "Next" to finish the crack. Tip: 1 files have been converted, with 0 errors and 0 warnings.
7. If you need to crack other files, press "Return"; Exit the software, and then press Finish.
8. After the crack is completed, a file named blackbox-keys.txt will be generated in my document, and it will also be deleted, which has no effect on the cracked wmv file.
note:
If you get the Windows error 80030002 when looking for Kid in the V9 store, you can use the drm2wmv tool.
Second, the use of DRM2WMV
DRM2WMV tool deletes WMV files that FairUse4WM software can't read, and the operation method is very troublesome. If there are no special problems, it is recommended not to use this tool.

The following things can be downloaded here.
The compressed package contains drm2wmv and drmdbg, and also provides a drmv2clt.dll, which is the dll version of windows media player 9. 0. 0. 3250. If yours is old, please replace it in c:\windows\system32 (in system32 of your system disk).
2. Modify the behavior of 9, 10, 1 1, 12 in drmdbg.ini directory in the package:
The following is a quote:
drmv 2 CLT = 1；
drmclien = 0；
black box = 0；
indivbox = 0；
Save.
3. Then run drmdbg.exe, which will automatically start the windows media player media player. Open the wmv file to play.
The player needs to connect to the network to obtain the certificate, and then a "Get License" window appears with "Play" and "Cancel" buttons, and shows that the license is being obtained. After obtaining the license, you can use the Play button.
After clicking the play button, a window will pop up showing the child and Sid.
Every WMV is different, and neither are the children and Sid. I just give an example in the next paragraph. As follows:
The following is a quote:
DRM2WMV2
kidsthisiskid = =/KIDSIDthisissid =/SID
Information/information
/DRM2WMV2
And the last piece of code has been sent to your clipboard (that is, the code has been copied), click OK.
4. Open Notepad after confirmation, paste it in and save it as "your wmv file name". key
For example, your wmv file name is abc.wmv, and your saved file name is abc.key
When saving, select All Types instead of txt as the last type.
5. Then put this key file in the drm2 directory under the drm2wmv 124 1 directory.
6. Then put your wmv file in the drm2wmv 124 1 directory.
Drag the wmv file to drm2wmv_e.exe,
At this time, a window should pop up to tell you the peeling process and show the progress.
7. The stripped files are in the same directory, and the video file is named [NODRM] your wmv file name. Wmv is a wmv file without DRM protection, which can be played offline.
If there is something wrong with wmv video, you can fix it first and then remove DRM protection.
There are some advanced applications, please see the original post.
Third, use the tool software DRMGUI.
The DRMGUI tool should be very useful, but I failed the test. WMP9 environment.
Download DRM GUI v1.1.2.1.
Address: 00.htm 2008005288, 39250677s.
Installation: all the way to confirm that the installation is complete.
Use: Run DRMGUI, prompt to install another software (windows script 5.6), and continue to confirm the installation.
Windows script 5.6: produced by Microsoft, it is by no means rogue software and bad plug-in, but the purpose of installing it is unknown.
After installation, the system restarts.
The running interface is as follows:
1. Select the letters and positions of "Input Path" and "Output Path";
Note: DRMGUI will process all wmv files in this directory (batch processing), and it is recommended to transfer other WMV files that do not need to be processed; And you have to double-click the folder to determine the path. When you click it, it still points to the previous directory.
2. Click the "Get Crack" button to start processing. (as shown in figure 2)
DRMGUI will call Windows Media Player, which may pop up a download license window. After downloading, click Play.
After that, a pop-up window shows garbled characters. Never mind, just wait until the show is over.
3. After processing, a name is [no DRM]-* * *. Wmv appears in the output path directory.
4. The program will also create a new folder named drm2 on the desktop, including a registry file named DRM 2-i.key (It can be deleted without any adverse effect on the cracked wmv file).
Test:
1. Download the test video: [CCTV exclusive video] Korean equestrian fell to death (534KB).
Download address:
MMS://yayunwod.cctv.com/tiyuxinw ... 00 _ 20061207 _122.wmv.
Personally, I think today's CCTV should use more advanced encryption technology.
2. Use Windows Media Player to play video.
You must make sure that menu-Tools-Options-Privacy-"Automatically obtain license for protected content" is checked, otherwise it cannot be played.
Before playing, there will be a prompt that the license is being downloaded.
When playing normally, check the menu file-Properties-License-License Details.
Right-click the file to view properties-the license is "protected content";
The status bar shows "Protected: Yes"
3. Use DRM GUI V1.1.2.1to process the video according to the above method.
4. Use Windows Media Player to play the processed [DRM-free]-tiyuxinwen _ 300 _ 20061207 _122.wmv.
Check the menu file-Properties-License-License Details again. (Everything in the box disappears);
Right-click the file to view the properties, and even the license label is gone;
The status bar shows "Protected: No"
Play with storm video;
It can also be played normally when transferred to other computers without networking;
You can edit it using Windows Movie Maker.
