I started over again and updated to the official firmware, not a custom one. With the wrapper on, I cannot play anything. I selected a few different 4k movies and the screen goes black, except for a grey bar across the top and in the upper hand corner it says himediaplayer. it will stay there, doing nothing until I hit esc or return. I'm then back at the kodi screen and there is a box that says external player in use, click OK when playback is done...or something like that.
With the wrapper off, playback works but with very poor results for 4k movies - as we already know is a bug.
From reading in this thread, the wrapper calls another video player, but doesn't respond. Perhaps I'm missing a app or something?
I play movies from my nas via smb share, and yes with password. Is the smb share password issue still a bug? If yes, they need to fix this or it is a show stopper! I will not have shares without passwords and this unit is useless to me if it cannot play my movies from my nas via smb.
Update after more testing: I confirmed that if the smb share has a user id and password, the himedia player will not work with wrapper installed/enabled. I launched himediacenter, went to LAN and auto searched for my smb share. When I click to create a shortcut, it prompted me for the user id and password. That saved it as a shortcut to my nas. I then launched kodi with the wrapper enabled and it worked. It can now see and play the 4k movies. I still think the PQ still needs attention, but at least it can access my nas via smb with a user id and password. I rebooted and it still works, so seems like a good work around.
