So oled tvs' internal media player and the oppo 203 are still the best ways to watch these DV remuxes?
But TV internal players aren't the best for playback, they lack chapters, may lack capacity for some audios (LG CX for example lacks DTS support).. lacks PGS support.. is it really worth it?
Your right, it probably isn’t worth the hassle, I have gone back to ripping FEL titles as Movie only ISO and watching on the Chinoppo, I upgraded my server with an extra 24tb of the Christmas break so I’ve got space to play with for a while.
Do love the convenience of Kodi / Plex/ HT4 though ☹️

The Firestick Dolby Vision decoder panics and renders a black screen when it encounters a file that contains both Dolby Vision and HDR10+ metadata.
The source of the --skip-hdr10plus switch :)

I basically implemented the same behavior on the fly before the data gets sent to the decoder.
I wonder is possbile to force non-dv video to play as dv via kodi on Shield TV?
It would help to better understand "red push" cause on Shield.
Since p7 and p8 are affected (both in TV-led and Player-led modes) and p5 is not there is only logical conclusion that something wrong with YCbCr processing on Shield's DV decoder. P5 is IPT
To prove it we should play plain HDR10 or SDR video via DV decoder.
But there is not possible for user to force DV output on Shield for non-dv video.

Eventually you might be able to get on the fly conversion from profile 7 to profile 8.1, at least with Kodi.
Then all files would be compatible with most devices at playback.
I don't believe streaming devices will ever get full support for profile 7 FEL.

I've already patched my Kodi to fix the DoVi/HDR10+ issue with the Firestick, so it's not that hard.
Just takes someone to do the work, basically just porting an RPU parser to C++.
Too bad yusesope hasn't shared their code, otherwise we'd have it already.
I'm out of the loop. Kodi can pay DV content now? Is this only for mp4s or mkvs as well?

Also if you or anyone else could answer this: assuming playback of DV content in remuxes improves in the near future, will it make any differences whether the TV supports TV led DV vs player led DV? I'm debating between a sony x950h (player led) and x900h (TV led-what I currently have but considering switching due to better PQ/higher peak brightness in the 950h)

I can't unfortunately. The return period for my x900h ends in mid February and if I return the TV I wont have one to replace it (I sold my old TV).

I can try forcing LLDV on the shield on hdr10 content it’s possible, did it before.

I don't know about the Shield, but the Firestick only triggers Dolby Vision for the TV when there is proper metadata.
Otherwise, there is an option to have Dolby Vision enabled all the time. I don't think the Shield can do that.

So an oled CX owner on avsforum just confirmed with me that the tv's internal media player couldn't play this DV DL test file properly: https://drive.google.com/file/d/1NK71Ck ... XLXEa/view

On my C9 it looked fine and played fine. Seems like LG did remove the ability to play dual layer dolby vision file from the CX (and probably upcoming oled tvs as well). That sucks.

Can you please recheck Shield TV on MIF bath fight scene with capture card?

Is it me or there is some noticable improvement with 8.2.2 update?
Can't spot red blocking while playing mkv via plex.
DV triggered

Maybe I just missed this very frame.

Meanwhile Dr Sleep still has noticable red push

As of the recent update CX can play P7 Dual Layer mp4s. But MEL only.
The 07.06 file you linked to is Dual Track, not Dual Layer.

Sorry could you explain what is the difference between dual track vs dual layer? And what do you mean by MEL only?

To throw in a little detail to the mix. CX can play Dual Track DV MP4 files, but the file has to have been made using mp4muxer v1.0.0. The latest version of mp4muxer, v1.0.1, does something with file that it isn't played by the tv anymore. I checked the code changes, and it may be the change where they introduce the Alternate Group flag. With v1.0.1 this is set to 1 for both the BL and the EL+RPU tracks, previously this was 0. The BL track is also set as the "default". It may be that this is either wrong for DV files from a MP4 spec point of view, or, the TV has a bug requiring the group to be 0. It is still required to be MEL.

Erm yes I think I had things the wrong way around. Unfortunately my hard drive broke yesterday so I can't check all my test files. Just ignore me!
