When I replace the actual matroska dll included as part of the 1.20.3 msvc binaries and then run gst-inspect it reports the following (gst-inspect-1.0:17092): GStreamer-WARNING **: 15:44:18.959: Failed to load plugin 'path\to\gstmatroska.dll': The specified module could not be found. This usually means Windows was unable to find a DLL dependency of the plugin. Please check that PATH is correct. You can run 'dumpbin -dependents' (provided by the Visual Studio developer prompt) to list the DLL deps of any DLL. There are also some third-party GUIs to list and debug DLL dependencies recursively. No such element or plugin 'matroska' I have also built the pango dll in the same way and when I replaced that and did the same thing the details of the plugin were reported correctly. One thing that I have noticed is that the dll built from source can be inspected by the version of gst-inspect also built from the source. Similarly, if I replace the dll built from source with that included by the installer and then use gst-inspect built from source then I get the same error as shown above. My hunch is that it is something to do with matroska’s dependency on the z and possibly bz2 dll’s. Installed version has the following dll’s z-1.dll bz2.dll gstbz2.dll When built from source I only have the following dll z.dll I wonder if anyone can shed any light on what I am doing wrong or what else I need to do when building matroska. Many Thanks </div> </div> </blockquote></div>
