Dual Layer Dolby Vision will play it will just miss the enhancements from the 2nd layer. If it doesn’t play could you prepare a sample and grab the logs from trying to play a Dual Layer Dolby Vision video?
Dual Layer works with 2 video streams in the container, at the moment Android / MediaCodec / ExoPlayer v2 / Plex only knows how to play with 1 video stream. The decoder by Dolby would need to accept both video streams and produce a single output. As such until Dolby add support there doesn’t appear to be anything we can do except to play only a single layer from dual layer Dolby Vision videos.
