Transcoding to Shield When DirectStream avaiable

[DaveR1974]

I had Jellyfin 10.18.13 installed on my Openmediavault server (7.1.1-1 "Sandworm"), and Jellyfin for Android TV (don't know the version number, just that it was the previous) installed on my Nvidia Shield TV (2019).
This worked fine with all my content (transcoding disabled as not needed).
On updating the App to the current version (0.16.11) I got the notification to update the Jellyfin server to 10.19.0 before the next App update, which I did (first 10.19.3).
Now the App is unable to correctly play my Dolby Vision content (DV is not displayed on my TV and colour is all wrong). The files even have HDR10 fallback that is also not detected. The files all worked before the updates.
I have since updated to 10.19.4, and still the same issue.
The files all play fine via Kodi v21.0 when Kodi accesses the OMV server.
HDR only files are unaffected.
Since seeing your reply DeadPirate, I checked the logs, and now there are now "FFmpeg.Transcode" logs that were not there before.
I now cannot find the setting I had originally set to disable transcoding.
