Next time, I'll test a little more before I go posting an "answer". That works, and my conscience is somewhat clearer. Regsvr32 /s %SystemRoot%\System32\wvc1dmod.dll Rem Dumb thing doesn't seem to register itself Start /wait rundll32.exe setupapi,InstallHinfSection DefaultInstall.Nt 132.

#WHY DO I NEED A VC1 CODEC SERIAL#
You will need to provide your serial as the codec license keys are specific. Visit the Raspberry Pi License Store and buy the MPEG2 and/or VC1 codec license key. Even then, the INF installer (invoked from the command-line or from right-click / Install) doesn't actually register the DLL! Here's a deployment script that can be placed into a share on a server comptuer and invoked as a startup script. Why do I have to buy the MPEG2 Codec License. Rundll32 doesn't seem to want to run unless the path to the INF is specified as ".\wvc1dmo.inf". I'd probably package the DLL into an MSI and deploy it that way. ** For WMV3 (Windows Media Video 9) in AVI, I personally recommend using the VCM (Video Codec Manager) instead (Microsoft’s own WMV3-in-AVI encoder/decoder).Quick and dirty way - Extract the files and run: rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 wvc1dmo.inf While there was much rejoice recently at the patents expiring for MPEG-2, this makes little difference to Pi users, it seems.

WMVA is the fourcc for Windows Media Video 9 Advanced Profile (but it’s no longer used) The point of buying the license keys is to enable hardware decoding of MPEG-2 and VC-1 see Why does the Raspberry Pi need a MPEG-2 licence for more information on why you might want this. (blame Microsoft for the dumbass numbering scheme) WMV3 is the fourcc for Windows Media Video 9 Many apps therefore use the codec in a wrong way as required extradata and data format are not properly specified. nVIDIA does have VC1 HW on their Tegra chips but usage is problematic due to the mentioned lack of a standard. WMV2 is the fourcc for Windows Media Video 8 While VC1 is supported by lots of chips in HW, most devices lack a proper driver/codec for it due to the missing standard. * WMV1 is the fourcc (four character code) for Windows Media Video 7 The above steps should work for Windows Media Video in AVI.įor WMV in ASF, you will also need fcchandler’s WMV plugin for VirtualDub (as mentioned by Bob Dole above). Your file should be decodable in VirtualDub. I tend to pick wmv9 rather than libavcodec.
on the right, look for the line WMV1/7*, WMV2/8*, WMV3/9**, or VC-1 (those most of interest). when you’re done, run the VfW configuration (either from the last window during setup, or from your start menu) If you don’t need anything being decoded, uncheck everything under audio and video codecs when it offers you to let ffdshow decode them
During installation, check 'VfW interface', and the VirtualDub plugin. (yes, some fools lossless transcode their WMV1 and WMV2 to AVI - when it really belongs in ASF/WMV) These steps are for editing of AVI files encoded in WMV1, WMV2, or WMV3 in VirtualDub (or any other application that uses the VfW (Video for Windows) architecture).

A codec is a computer code that performs its function whenever the file is called up by a piece of software. The codec encodes, compressing the data for storage or sending, then decompresses for playback or editing.
#WHY DO I NEED A VC1 CODEC UPDATE#
Gotta make an update (well should have a while ago, but never remembered the existence of this thread). What do they do In the simplest terms, because video files are so large, you need a way to make them smaller.
