I can't vouch for profile 5, but at least since latest firmware my Zidoo Z9x has shown excellent playback of DV profile 7 and 8 mkv with lossless audio. Admittedly it is not too long ago I started with profile 8 and I didn't create much of them.


@RESET_9999
I am curious about the Z9X unstable playback of profile 8 as mentioned in the spreadsheet. Can you name a specific title where the Zidoo shows the RPU issue? I want to have a look at this. See if I can answer some questions.

Shang Chi P5 imax web-dl converted to P8 and injected into HDR10 imax web-dl. RPU goes out of sync after 30 minutes... fine on shield , x700 and C8

Or are there others that will do the job?
Sony x800m2 is the way to go. support all profiles with lossless audio and is bug free.

Thank you, I'll have a search.

You didn't have this "P8 issue only on Z9X" with a self-ripped disc and conversion? If so, I'd like to hear what movie(s) you can recall.

I don't remember. I watched about 10 movies and it happened 2 times(Only remember Shang Chi) and then got rid of the device, could not trust it anymore.

We can generate DV for any HDR10 movie... MKV container is useless to me and this thread is about Dolby Vision , not HDR10/SDR playback...

I don't think oppo203 clones can do 'truehd mkv'.

For ts,m2ts, p7 dldt

Is using tsmuxer alone the same as using ffmpeg for demux and tsmuxer for muxing ?

Sure, im just saying there's more to consider when picking a player, but sure for DV the 800m2 is a good proposition,
even with everything in my chain replaced it still behaves oddly sometimes for me, but im sure the oppo will have similar or other quirks.

just need the trick of swapping to a secondary audio track and back, as far as I know.

Not sure what's the value of generate DV from HDR10. DV's EL+RUP is suppose to be the difference between master tape and HDR10. Sure you can evaluate what's in HDR10 and generate something that may be pleasing to some people.

Definitely not the x800m2 causing that(unless you're talking about non-DV stuff again). I now have watched 15 movies without a single issue and I'm more and more confident that this player is as stable as the x700.

Yes, for DT-DL, you only need tsmuxer.
I stopped using ffmpeg for demuxing, it was causing me problems. Tsmuxer works better. mkvextract too.

Code: Select all

Error: Condition failed: `self.max_display_mastering_luminance <= MAX_PQ_LUMINANCE` (38528 vs 10000)
Have you already find out what the issue was?
I encounter the same issue now with two movies from AppleTV+
Hope we can sort this out!

Hello, I'm new here.

I saw an avsforum thread talking about quietvoid's dovi_tool and how to attach a web-dl DV layer to your HDR remux using this tool. It led me here.

I downloaded the code in .zip from Github but I'm very confused how I may 'open and run' the programme. Am I supposed to 'build' it first? But I don't know how.

Could someone please help? Many thanks in advance.

For windows, you have to extract .tar.gz file into .tar file. Which you extract to a folder called "dist". In this folder is the tool.

It's CLI, check https://github.com/quietvoid/dovi_tool#readme on how to use.

Thank you for the help. I just managed to run it in cmd. But to deal with a .mp4 rather than a .hevc, ffmpeg is required. And I figured I'd have to install it and add ffmpeg.exe to Path.
