LG OLED C9 issues with airplay2


I just bought an LG OLEG C9, which has Airplay2.

When streaming 1080p videos via airplay, it works, however in dolby 2.0.

Already in 4k HDR movies, the video is not transmitted, only the audio and also in 2.0.

I wonder if it’s a limitation of Infuse or Airplay2?

Sorry, my english, I’m brazilian and I’m using google translator.

Airplay 2 doesn’t support HEVC encoded videos, which is the default format for 4K. When you airplay from iPhone photos app, for instance, it is transcoding on the fly to h264
