Finally, I found the time and checked your version of KODI-18 for the main core. In short - all my test videos (including 4k) come with HW .
When playing 4k, KODI shows a load of about 11% to Station p1. Great job. Can you build and upload new versions for the main core to the network reps ? It is interesting to try the new versions of KODI-19.
