Hi Sam,
AMLogic grabber works as a charm. Working great on the Vero4K. Now I’m only missing the usbtv driver to get the V4L grabber running.
Also found this thread (OSMC and Hyperion - #17 by penfold42) which mentions support was added to hyperion-ng. AFAIK the new version requires QT5 which I never got working on OSMC. Kodi crashes when QT5 is installed.
