All the ZEN NDI apps have been recompiled in Oct-2021 using the NDI® v5.03 SDK, in some cases with other fixes & updates, and are available on the Downloads page. As to what difference using NDI 5 will make, I really don’t know, since I haven’t changed anything significant in the source code, just recompiled the existing code and included the NDI 5 DLL file in the release. However, since it’s this DLL that provides the encode/decode functions, there may well be some improved efficiencies and optimisations.

Note that these Oct-21 downloads only include 64-bit .exe files, since I don’t believe there’s any significant number of users running 32-bit systems any more.
