DolbyVision issue v0.19.2 AndroidTV client

[dess4k]

Hi
I am using a Google streamer 4K with the 0.19.2 Jellyfin AndroidTV version. 
TV is a Samsung S95B (HDR10+ and not DV)
The issue occurs with a 10.11.2 server version (installed from scratch on a proxmox lcx) and also on a 10.10.7 server version (installed directly on a Synology Nas and waiting to finalize my tests before upgrading it to 10.11.x).

When playing a file with Dolby Vision (with and without transcoding) from the Google streamer connected to the Samsung TV, I have "sometime" a fast black screen. I tried to modify a lot of parameters both on the Jellyfin App/Server and Google streamer sides with no results.
After testing several different files, I noticed the "black blink" always appears when there is a camera transition. So really often...
I suspect the v0.19.2 Jellyfin client because I did not have this strange behavior in previous AndroidTV client version. Moreover, It works fine from chrome and from another device supporting DV (also with the same AndroidTV app version)
I check the v0.19.3 release note but nothing related to that "bug". (anyway this version is not yet available on playstore so...)

Any help really appreciated

I made other tests.
Forcing HDR10 conversion from the Google streamer fix the issue on DV files on jellyfin but make me loose the HDR10+ capability on amazon prime.

Definitely a bug somewhere

Am I the only one having this issue ?

No, not a single one. The developers completely broke DV support in client version 0.19.x. The client incorrectly provides the server with device information, and the server starts transcoding even though the device fully supports DV. Everything can play DV on my TV, Plex, Emby, and any other player, but Jellyfin can't now, even though it could do it perfectly before 0.19.x. These issues are documented in detail on Github. It's mind-boggling how the developers even allowed the new version of the Jellyfin Android TV client to be released.

Insane how these volunteer developers don't do what I pay them for!

It's incredible that any other free player plays DV. It's incredible how they managed to not break something that works, and it's incredible how they still haven't managed to get it working again.
