Oh.. I use the native one.. that's probably it.. I figured the native one will be most stable over time, and server versions..  seems the plugin works better...

Im having the same problem after installing a fresh server. Its a emby fault not a LG fault, playback was fine before the reinstall and now some users are getting black screen with HEVC content.

What's the playback method (DirectPlay,DirectStream,Transcode)?  Any ffmpeg logs?

Can you provide a sample video for testing? Best guess is that it's trying to direct play a variation of hevc that the TV does not support. Currently the app just treats hevc as all or nothing in terms of direct play vs transcoding, but really it needs to evaluated for all of the different hevc profiles so that it's not trying to direct play something that the TV can't handle. That's something that we are looking at for the next app update.
