Input filters

Posted on August 22nd, 2008


VirtualDub exposes a new application programming interface (API) for a new type of plugin, input drivers!
Support for these input drivers has been introduced with v1.7.2, and SDK updated with v1.8.1, so older versions of VirtualDub won’t be able to use it.
Input filters allow to support some new input video and audio formats, so that input files not in AVI or MPEG1 file formats may be processed in VirtualDub. This filters are input filters only; it doesn’t allow to output/save/render to new formats.


Input filters can be loaded creating a folder named “Plugins32” in VirtualDub’s program folder, and placing the “plugin_name.vdplugin” files into that folder. VirtualDub will find and use the plugins automatically, and the corresponding video file formats will be available in the “Open video file…” dialog. Some plugins may offer some extended options and display it if “Ask for extended options after this dialog” is checked.

Check the VirtualDub website for the Plugin SDK for writing your own input filter if you are a developper.
