lightsout 156 Posted October 21, 2019 Posted October 21, 2019 I remember in a thread someone was saying they had this working. I have a few files to test and my TV (TCL 625) only shows standard HDR when playing them through Emby. Anyone having any luck?
speechles 2055 Posted October 21, 2019 Posted October 21, 2019 You will only ever see the HDR logo on it. It doesn't show dolby vision you just notice it is working showing correct colors. It depends greatly on model on which store you get it from. My 50 inch RokuTV doesn't do DolbyVision but supports 12bit color through hdr10+. Roku supports hdr10+. But DolbyVision is more up to the demands of the retailer. I think it is the Best Buy models that do it. My buddys 65 inch TCL from best buy plays dolby vision but oddly shows the HDR logo overlay on the Roku clumsily.

My 5 and 6 series (65R625 just released) both do Dolby Vision and the logo comes up in Netflix. How can we really know it is doing DV through Emby, I have a feeling it is defaulting to the standard HDR metadata.

If it is direct playing there is probably a correlation to becoming a partner somewhere in the mix since DolbyVision requires royalty. That would make sense Netflix shows it. Same for Amazon and YouTube. They are contributing partners to paying Roku royalty for allowing Dolby Atmos and Dolby Vision. Same way Walmart does with Vudu. It might be this way with Dolby Vision and only apps that can actually get lower level access to a custom player can do it. Since we use the stock Roku video player every other non partner application does it may not support the meta data being sent.

Was hoping to play these files locally with the new Nvidia Shield. I guess DV ripping is in its infancy and we'll have to see how it pans out. I'm going to test a file from the TV's USB and see how that goes.
lightsout 156 Posted October 22, 2019 Author Posted October 22, 2019 No go on the USB stick, I could hear sound but the screen stayed black.
Luke 42077 Posted October 24, 2019 Posted October 24, 2019 So then it sounds like the device just doesn't support it.
lightsout 156 Posted October 24, 2019 Author Posted October 24, 2019 So then it sounds like the device just doesn't support it. Yeah, it can do DV, but apparently only through something like Netflix. So far I think only LG and Vizio TV's are reported to play local media that is DV.
Luke 42077 Posted October 24, 2019 Posted October 24, 2019 Perhaps they were able to negotiate down the licensing cost by agreeing to limit the apps that could use it.
lightsout 156 Posted October 24, 2019 Author Posted October 24, 2019 Perhaps they were able to negotiate down the licensing cost by agreeing to limit the apps that could use it. Not sure, seems like it is still in the beginning stages. @speechless up above thought maybe these apps had lower level access than the standard player. But as far as I know this is the same behavior on the fire stick.
adminExitium 355 Posted October 31, 2019 Posted October 31, 2019 This is probably the difference between single-layer & dual-layer discs with DV. Almost all the Web content is single-layer DV whereas the blu-ray remuxes (assuming they are your source) are dual-layer DV, which very few devices support.
