VirtualDub Plugin SDK 1.2
What's new in the Plugin SDK
Periodically new features are added to the VirtualDub filter API. Except where noted, these features are implemented such that their use is optional; old filters continue to work in hosts supporting newer versions, and filters can be made to work with older hosts through version detection.
-
Input drivers: API V4 (VirtualDub 1.10.1).
-
Video filters: API V15 (VirtualDub 1.9.3) and V16 (VirtualDub 1.10.1).
Warning: If you have set up your filter module to always target the highest available API version specified in the plugin header files, this release will bump your filter to API V16, which has some new restrictions on previously supported functionality. See Breaking changes for details.
- VDXFrame: Fixed bug in VDXVideoFilter that wrote broken script
config lines for filters that didn't export any via
GetScriptString(). - Video filters: Now covers API V14 (VirtualDub 1.9.1).
- Input drivers: Now covers API V3 (VirtualDub 1.8.0).
- Initial release.
