Google TV Streamer - Pink screen when playing Dolby Vision and freezes on HDR

[jdjta]

I have my GTS attached to my Denon AVR-S960H which connects to my Sony 55XH9299. Unfortunately on some occasions a purple/pink screen appears when I try to get play DV-content (ripped 4K discs streaming through my server). 

I already tried troubleshooting this by switching out HDMI-cables and go through all settings. I did notice that if I change the Dolby Vision-mode to Low Latency (from 'Auto') I get a black screen (no longer pink/purple). I also bypassed the receiver to rule out issues there but it does exactly the same.

The other issue I noticed is some HDR-content sometimes try start but freezes at the first frame it shows.

I also tried to check the colour space format but the GTS no longer seems to have this option (the CCwGTV 4K did have a seperate setting).

Thanks for the update. I got it too, it's too early on my end to confirm it's fixed but some goat in reddit also mentioned this as a fix which he's still testjng. I'm starting to get more positive about this.

Unfortunaley I have the same issues. I just bought the Google TV Streamer to finally enjoy Dolby Vision Content. Some Files work fine others have the pink color problem. When I watch the content on my Android Pad it works fine. Please fix this google!

Make sure you're on January update, fixed the problem for me

The January update did not fix the problem for me.

(at least not while using Kodi and looking at offline Dolby Vision content)

I'm in the same boat, the update didn't fix it for me either, but id you're using Kodi, there's an easy fix as far as I know.

Can you try selecting either HDR10+ or Dolby Vision in 'Settings -> Player -> Advanced -> Allowed HDR dynamic metadata formats?

I'd love to know if it works for you or not.

Yes, Disabling Dolby Vision in settings works and I'm pretty sure it has always worked if I remember correctly (not only with the January update). My TV still says "HDR Content" (instead of "Dolby Vision" so I guess the DV gets converted by Kodi to normal HDR or HDR+.

Another thing that also works is if you disable the "Allow hardware acceleration - MediaCodec (Surface)" in the same settings, but sometimes the video gets choppy then (most likely to the CPU not being powerful enough with HW acceleration). 

And for completeness; enabling "Dolby Vision compatibility mode" does not help.

My solution to the problem was to get an "Ugoos AM6B Plus" and install CoreELEC on it. These small computers are one of the few that handles Dolby Vision perfectly. It is really snappy and works perfectly fine.

Since you've done extensive testing yourself, do you mind looking at my results and confirm if you've noticed the same problems?

My conclusion was a problem with the fallback from DV to HDR10+ on tvs that don't support DV.

I've tested this by manually removing both DV and HDR10+ metadata separately from the file. In both cases it works, that's why I think it's only a problem when you have to fallback from DV to HDR10+.

Regarding "Ugoos AM6B Plus", I guess there are many devices out there that work. Even the old CCwGTV works fine for me, if only it was a little more snappy.

[Johpe1]

My TV does support DV and some of the DV content I have actually does work in the Google TV Streamer (and then the TV correctly displays "Dolby Vision" as an overlay message). And some DV content just turns pink (which I don't really know why), maybe it has to do with the DV profile 7 (FEL) that I think is known to be problematic on a lot of HW.

Very weird, thank you for your time.

I selected movie mode in picture settings and it worked for me...I do have a google tv...
