The com.sun.star.media.Manager service is documented here: https://api.libreoffice.org/docs/idl/ref/servicecom_1_1sun_1_1star_1_1media_1_1Manager.html It is implemented in four places: https://opengrok.libreoffice.org/xref/core/avmedia/source/gstreamer/gstmanager.cxx?r=8b091048#63 https://opengrok.libreoffice.org/xref/core/avmedia/source/gtk/gtkmanager.cxx?r=61717b21#46 https://opengrok.libreoffice.org/xref/core/avmedia/source/qt6/QtManager.cxx?r=441d8ed9#50 https://opengrok.libreoffice.org/xref/core/avmedia/source/win/manager.cxx?r=bbcf2357#67 But it is impossible to create its instance using this Basic call: CreateUnoService("com.sun.star.media.Manager") On the other hand, it is possible to create it using e.g. (on Windows): CreateUnoService("com.sun.star.media.Manager_DirectX") because that undocumented service name is defined in https://opengrok.libreoffice.org/xref/core/avmedia/source/win/avmediawin.component It is possibly required to keep this undocumented name supported (because of countless uses of this); but the correct name needs also be properly defined in .component files, to enable its cross-platform construction.
By the way, the mac implementation even broke the service name in the implementation: https://opengrok.libreoffice.org/xref/core/avmedia/source/macavf/manager.mm?r=9ece0ae7
I believe you, so I will set to NEW.
