7/1/2023 0 Comments Why do i need a vc1 codecWMVA is the fourcc for Windows Media Video 9 Advanced Profile (but it’s no longer used) (blame Microsoft for the dumbass numbering scheme) WMV3 is the fourcc for Windows Media Video 9 WMV2 is the fourcc for Windows Media Video 8 * 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). Gotta make an update (well should have a while ago, but never remembered the existence of this thread).
