WVC1 Codec

Recommended Posts

I wanted to play that WMV video but I couldn't because of missing WVC1 codec.

Wikipedia says it is Windows Media Video 9 Advanced Profile and that it requires Windows Media Format 11 Runtime or Windows Media Player 11.

Instead of trying to update files from those packages I found out that MS distributed last year a wvc1dmo.exe package, a copy of which I have been able to find here.

It contains the WVC1 encoder and the decoder in separate files. The encoder does not work as it has missing functions in dependencies but the decoder works OK and allows to play the above file. It is wvc1dmod.dll and it just need to be copied somewhere and regsvr32ed.

It is possible that more recent versions of wmvdmod.dll than the one I have installed (from WMP10 or 11) also allows videos using this codec to be played on 98SE/ME but I am not sure as I haven't tried that.

If of any help the said video plays on win98se using a later version of vlc.

Yes indeed, I have just tried that after unregistering wvc1dmod.dll and making sure Graphedit would not build a graph out of the video.

There is a download link in the first post of this thread. Maybe that's what you are after.

Windows Media Video 9 Advanced Profile (WMV9AP) Update Beta for Windows

2000/XP/2003 includes SMPTE VC-1 standard + Advanced Profiles support

(WMCMD.VBS):

WMV9AP [899 KB]:

http://www-pc.uni-regensburg.de/systemsw/W...dia/wvc1dmo.exe

To install wvc1dmo.exe :

1. Create C:\TEMP (if not already present) (example):

MD C:\TEMP

2. Run:

WVC1DMO.EXE /C /Q /T:C:\TEMP

to extract the files into C:\TEMP .

3. Open Windows Explorer -> right-click on WVC1DMO.INF -> select Install.

This will copy the 2 DLLs to %windir%\system [%windir% = usually C:\WINDOWS]:

WVC1DMOD.DLL

WVC1DMOE.DLL

and will also properly regsvr32 them into the registry.

4. Done.

If "that WMV video" is a clip of choosing a custom color, the codec seems to work fine on my 98FE box.

WVC1DMOE.DLL did not copy or register. Couldn't register it manually. WVC1DMOD.DLL copied and registered normally.

Found out that WVC1DMOE.DLL works only under Windows XP/2003/Vista with WMP11 installed.

To make this work under Windows 98/98 SP1/98 SE/ME, please follow these updated instructions:

1. Create C:\TEMP (example) from a DOS box:

MD C:\TEMP

2. Download wvc1dmo.exe (see above) into C:\TEMP .

3. Run:

C:\TEMP\wvc1dmo.exe /C /Q /T:C:\TEMP

4. Copy WVC1DMOD.DLL from C:\TEMP into %windir%\SYSTEM [%windir% = usually C:\WINDOWS]:

COPY/Y C:\TEMP\WVC1DMOD.DLL %windir%\SYSTEM

5. Run this command from a DOS box:

REGSVR32 %windir%\SYSTEM\WVC1DMOD.DLL

6. Copy + paste text between cut & paste lines below in Notepad -> save as WVC1_9X.REG (example) -> (double)-click on WVC1_9X.REG to merge into Registry:

-----Begin cut & paste here-----

REGEDIT4

------End cut & paste here------

7. Delete C:\TEMP .

MDGx - thank you very very much for help with this new codec! Your guide is working like a charm on Windows 2000! (there it need the reg file to manually register the DLL) Keep up your good work, mate!

COKEDUDEUSF -

How do you know if the video you have needs this?

I would say that GSpot will show ya... look:
