yes my pc is self built not store built and not DV certified at all - my PC monitor is HDR10 only not DV (my TV though is)

with that dolby windows plugin installed rpu changes in dv8 files which that test file demonstrates - display correctly on my computer and playback with the RPU changes applied/displayed/apparent - uninstall the DV plugin and the video plays back without any changes being apparent even though the text in the test video indicates you should be seeing changes
I build my PC myself too, not sure what this has to do with this?
You haven't answered my question... Does it trigger DV on your DV TV ?

probably not, so it tonemap DV to HDR10 (or SDR). That's my whole point, the DV to HDR10 (or SDR) tonemapping from the dv extension sucks big time.
I said it does not trigger DV on the TV when hooked right up to the TV it stays in HDR10 - but the RPU dynamic metadata is still displayed and applied (very apparently) all the same on playback when that plugin is installed - and does not when it isn't - that shouldn't be happening if it was only HDR10/SDR playback - so it is playing back/displaying the DV metadata on my uncertified computer, not just only the underlying base video - that's what I was trying to highlight

yeah, we already knew that when the extension was first available months ago.
I said that the DV to HDR10 (or SDR) tonemapping is off (regardless of the DV metadata).... My x700 (newer firestick TV too) can do exactly the same but the tonemapping is right (well except for the raised black levels)

plus the Windows player doesn't support lossless audio anyway and has incorrect static metadata.
Sorry for my English.

It is interpreting the RPU, as you say, but I do still think it's more accurate to describe this as a "DV to SDR/HDR10 conversion". I don't think it's the same as player-led DV. My understanding is that with player-led DV the TV sends parameters about itself to the player (e.g. its brightness capabilities) and the player feeds that into the magic DV algorithms along with the RPU to produce an output signal specifically tuned for that TV.

With this Windows playback, it's not receiving any parameters from the TV/monitor so it must just be interpreting the RPU in a generic way. Perhaps that's useful, but we should be clear that it's not really the full DV experience.

Hi, is it somehow possible to convert profile 8 to profile 5?

I have a file with dvhe.08.06, BL+RPU (and also with HDR10+, which I dont need) and I want to play it on my LG C7.

Thank you very much!

No. Are you sure your TV doesn't support profile 8?
It works on the C8 with ts files.

weird, profile 8 m2ts files worked in my lg b6
Maybe it's because of the HDR10+

EDIT: I've tried to remove HDR10+ but it's not working either.

Hello, I haven't been here for a long time... but is there now a player that can play mkv with DolbyVision Duallayer (native EL) ?

My LG TV + Bluray Player can only play mp4 with AC3 Audio.

A question for those with a Sony x700. I picked one up on sale about 3 weeks ago and just wondering if this glitch I'm experiencing is happening to everyone? When playing a dual track .ts Dolby Vision file via USB, if i stop the film and select another DV film its like it tries to play the two tracks independently one on top of the other and the screen is scrambled. Powering off and on fixes the issue for the next selected film but reappears again if i attempt another.

Can I ask how you remove HDR10+ because I need to do that on some files.

You can try this: https://gist.github.com/quietvoid/175d7 ... 9eb1bd2c38
It's based on yusesope's script.

Looks like what I need - can you tell me how I use the script though? I've installed python but I'm not sure how to use it.

You need to demux the video first, and then run the script on the HEVC file.
example: python hdr10plus_remove.py -i video.hevc -o processed_file.hevc

When I convert HDR10+ do DoVi, do I need to change something in generator_example.json or can I leave it as it is?
