They are many android devices with DV, they confirmed that device can read DV DL?

The price is similar to x700
not sure why your reply sounds so arrogant, maybe it's just me being tired :P can you name me some of these many android devices that can do dolby vision and, like I said, are NOT netflix or google etc certified (single layer) devices? it's special because it's the first one a dolby vision license that doesn't seem to require being single layer. but who knows, it's just why I'm keeping an eye on it..

A quick search; Transpeed X3, X3 Max, UGOOS AM6 Plus, etc.

Like I said they are many Android devices with DV support

no worries. none of these devices from what I've read have a dolby vision license though. there are many SOCs with physically capable hw, but it still can't do dolby vision without a license.

As much as this was a breakthrough and very exciting I feel like we are back to square one. Anyone else feel this?

UGOOS AM6 Plus is 1:1 hardware like the minix

Same SOC and GPU
SoC Amlogic S922XJ
GPU ARM Mali-G52 MP6
And the "Amlogic Video Engine" and more cheap

And remember, they don't respond your answer about DV DL

So did anybody tried to produce a single layer DV 60fps movie with hd audio using yusecope's second version of his tool?

I believe the 60fps DV movies didn't play without stuttering on LG TV's when they are dual layer right?

once again, it has physically capable hardware, but also needs a dolby license. Minix has told me they have the full paid license. obviously they haven't said about dual layer, or I wouldn't be 'keeping my eye on it' to test what it's capable of at launch. English is not your primary language though, so I forgive you :wink:

one more comparison: https://slow.pics/c/TyeCCLDz

no doubt in my mind, it's not identical. at least not from X700 vs Shield

after more comparisons with my TV internal app and the x700, I now believe the Shield actually output over-saturated color in DV.
I suspect it's because they send a bt2020 rgb 8bit signalwhile the x700 and the appleTV send RGB 8 bit ( no color primaries signaled).

wonder if it may be because of the AI-enhanced upscaler? I know that it's only supposed to be used for regular HD videos, but maybe it's still doing something to these 4k videos.

nop... AI upscaler is turned off, I hate it. https://www.avsforum.com/forum/39-netwo ... st58785700

on my end, anything that needs upscaling goes into HTPC/madVR. :)

Is anyone else having this issue with @yusesope tool
Throws an error and hangs the video works it is just missing the last second or so

I can still use the output and create a mp4 using dlb_mp4base and will play back on my Visio TV

Have you tried setting the Shield's output to YUV 4:2:0 10 bit or YUV 4:2:2 12 bit rather than RGB 8 bit? I could definitely see things looking different if not set to YUV.

Decided to get an X700. Used it to watch Casino Royale. Wow! It looked phenomenal, especially the intro montage.

I am seeing the same issue where I can only play a single TS file at a time. After that when attempting to play back the file there’s a giant red or green box overlaid on top of the screen. My solution to that has been a smart plug so I can turn it off with an app or with a voice assistant and turn it back on, so it really doesn’t bother me too much. I have confirmed that doing it this way leads to playback working again. Hey, as long as I don’t have to get up and physically unplug a cord, it’s worth it. :lol:

Had no problems with FF/RW. I read this on another forum, it was related to the M9702 but they experienced the same issue with FF/RW.

“ DVDFab 11.x Fastforward and rewind is broken if any Dolby Vision UHD BD is remuxed down to the main movie. They are aware of this bug. Going fastfoward past 2X speed will stop playback.

Please use CloneBD to remux any Dolby Vision UHD BD.
You might be experiencing that bug or..
DVDFab chose the wrong mpls. The main movie Titles without chapters.

Or, it was a bad DVDFab decrypt to clone/copy whole disc. Again, use CloneBD.
I think its a better, free, trustworthy software.”

Just curious if those people having trouble with FF/RW ripped with DVDFab.

Also, I had no issues with streaming Casino Royale from my PC to the X700 via Ethernet. I am sure there will be some films where there may be an issue but with this particular film it was flawless playback. Even paused it a few times and resumed without issue.

All in all I would say the X700 is definitely worth it if you’ve been chasing Dolby Vision for a while and just want a device that can play it back. It’s an incredibly niche use case, but we’re a niche audience!

Regarding yusesope’s tool, I honestly think his files are created correctly and he deserves a huge round of applause. I suspect the issue is on the client’s end based on everything that has been reported. Either way, absolutely stunning work on his part and his contributions to this effort of Dolby Vision playback have been immense, so I just wanted to say thank you so much for everything you’ve done and continue to do for us.

That's interesting. FWIW - and that is probably very little since this is very much "hearsay" - my pro calibrator (who is well qualified and does a lot of stuff for commercial Movie/TV productions as well as consult TV manufacturers) was negative about the implementation of DV in the 2019 SHIELD. We didn't discuss in any detail (because I had decided not to buy one) but I wonder if this is what he was referring to.

Congrats on the X700. Just to say that after the green screen of death, mine only requires powering on/off using the remote (or via CEC after putting TV in standby). Just in case that helps - but I like the smart plug solution :-)

R.e. network playback. I have a Vero 4K which only has 100mbps, and that is able to play every UHD mkv I have flawlessly via network shares. The developers of that product are adamant that gigabit ethernet is not required for lossless UHD rips, and they seem to be correct. However, they have very carefully engineered the cacheing so as to deal with any possible bitrate spike.

Like you I've also noticed that the X700 can play some movies just fine over 100mbps, but there are others which it definitely can not (a recent example for me was Doctor Sleep). I wonder whether there is a way to analytically scan movies in advance (i.e. for average bit rate and peak bit rate) to try to understand what thresholds are ok for X700 network playback. It obviously was never designed for people to play lossless UHDs over DLNA, but perhaps the majority of movies can be left on a NAS. It would be nice to be able to make that decision in advance on a movie by movie basis.
