Cross-posting here, in case someone has an idea.
Using the webos jellyfin player which is a thin wrapper around jellyfin-web.
Bug 1: DoVi 8.1 file triggers transcoding on LG G4.
Bug 2: Disabling transcoding for this user allows playing this file DV content just fine with direct stream, but the two audio tracks which are DTS HDMA and Dolby TrueHD with Atmos get transcoded to AAC (DTS and TrueHD passthrough options are checked in the settings)
I have the fMP4 checkbox unchecked. The passthrough for DTS and TrueHD is set to true in the jellyfin webos app options. My setup is capable of both TrueHD and DTS. LG is plugged to my AVR with eARC.
In the log file, I can see the transcoding happening to aac (-codec:a:0 libfdk_aac):
