Hello all… long time lurker, first time poster. I wanted to contribute my findings with the newest v9.28.0. Up until now I have been running v9.16.2.38798 on my Sony A80CK TV w/Google TV. After reading this post regarding the loss of DoVi playback when upgrading to v9.17.0.38861, my DoVi files would fall back to basic HDR. A changelog note stated “Player: fallback to HDR when DoVi profile isn’t supported.” I did not have the black screen problem when files w/HDR10+ were played when using the internal Plex app on my TV downloaded from the Play Store.
After regressing to v9.16.2.38798 all my DoVi files played correctly again in any format i.e. v7, v8, and either/or w/HDR10+ metadata included or not. At that point I turned Auto Updates off to prevent the app from updating.
After following this thread for a while and reading about this recent fix, I upgraded to the newest v9.28.0 offered from the Play Store on my Sony TV. After upgrading I find that all my v7 files, including those w/HDR10+ metadata fall back to basic HDR again. My v8 files, whether with/without HDR10+ metadata play correctly in DoVi.
My conclusion is that although your fix to strip HDR10+ metadata from v8 files works correctly now, all my v7 files including those with HDR10+ metadata still fall back to basic HDR. Something happened between v9.16.2 and v9.17.0 up until now to prevent v7 files w/or without HDR10+ from being played correctly in DoVi causing them to fallback to HDR, at least on my Sony TV.
I am hoping this fix can be applied to all v7 files as well, since v9.16.2.38798 plays everything correctly, for me anyway. So I’ve gone back to v9.16.2.38798 for now and everything is back to normal. Hope my post is not too long winded (too late). Thanks as always for all your hard work in making Plex a great program!
