Dolby Vision now possible through MP4 Mux.

thanks for your answer
I'll have to keep both external players then. Chinoppo only for FEL titles.

And if i want Play one MKV DV FEL? exist any external player? Dune I imagine not. only MEL.

The Chromecast apparently can do FEL but doesn't support lossless audio. I'm waiting for @manix to capture the total recall scene and compare it with the x700.

There's also the Ugoos AM6 ( I think) that is very interesting because it looks like it supports FEL and lossless audio.

[Romero91]

And what does Chromecast or Ugoos, what does not have Dune for FEL to work? For the same reason, don't you think Dune adds support through FW? i hope so if Another streaming devices apparently have FEL support now...

I have no idea, it's very surprising that not 1 but 2 streaming devices can do FEL...
But can they really do it properly? that's why I want @manix to capture the Total Recall scene with his Atomos Shogun.

For the same reason, don't you think Dune adds support through FW? i hope so if Another streaming devices apparently have FEL support now...

well, nothing is impossible I guess but IMO it's unlikely.
we also want to compare another sample because, while testing more scenes in Total recall, we noticed that the Dune's colors are slightly washed out in DV compared to the x700 DV and even compared to the bluray remux HDR10

Did anyone with a dune try kodi dv build ?regular xbmc does hdr fine on the dune.
Tested aquaman el test works on dune
Used tsmuxer on the mp4 I see the errors and lum shift only in iso mode to lite but has to be iso
According to the test file the dune is processing the el

As someone mentioned already, if you look at the S922X spec sheet (AM6 Plus SoC is S922X-J) on page 12:

• Amlogic Video Engine (AVE) with dedicated hardware decoders and encoders
• Support multi-video decoder up to 4Kx2K@60fps+1x1080P@60fps
• Supports multiple “secured” video decoding sessions and simultaneous decoding and encoding

Similarly, the S905D3 spec sheet (Chromecast with Google TV's SoC) on page 11:

• Amlogic Video Engine (AVE) with dedicated hardware decoders and encoders
• Support multi-video decoder up to 4x1080P@60fps
• Supports multiple “secured” video decoding sessions and simultaneous decoding and encoding

So, they are both hardware-capable of decoding 1x2160p@23.976fps + 1x1080p@23.976fps simultaneously, which is BL+FEL @23.976fps (majority of DV UHD releases). In theory, the AM6Plus could handle BL+FEL @60fps while the Chromecast with Google TV could not, although no 60FPS DV FEL UHD has been released to date to test this (Gemini Man is 2160p@60fps MEL).

The key thing enabling proper FEL decode on these SoCs seems to be the AVE-10 hardware decoder:

Amlogic Video Engine(AVE-10) off-loads the Cortex CPUs from all video CODEC processing. It includes dedicated hardware video decoder and encoder.

Perhaps this explains why the RTD1619DR (Dune Pro/Max Vision 4K and Zidoo Z9X/UHD3000/Z10 PRO/Z1000 PRO) is not capable of decoding FEL, despite having a very similar CPU/GPU (6xARM Cortex-A55 + ARM Mali-G51 MP3) to the S905D3 (4xARM Cortex-A55 + ARM Mali-G31 MP2) and S922X-J (4xARM Cortex-A73+2xARM Cortex-A53 + ARM Mali-G52 MP6).

With Ugoos AM6 plus/Kodi Matrix DV edition (thanks @Fandangos and @quietvoid) Saving Private Ryan (MKV DV) no flicKering like the m2ts on Sony X700.
This is the first time that a device (except Sony X700) does not flickers on this film.
I tried Firestick 4K, Shield 2019 and Google Chromecast with Google TV.
In Ugoos (latest firmware 0.40) also HD audio (True HD Atmos and DTS X) works in passtrough in Kodi.
My soundbar confirms.

I have ripped the movie The Meg to .mp4 DV single layer using DVDFab and it shows up as DV in the Infuse GUI and plays as such just fine. The colors seem the same as when I play the disc in my Sony X800M2. I’m an ISF Certified Calibrator amongst many other industry things for 30+ years so would notice if color was amiss. What color issue is it that I’m supposed to be looking for exactly?

The only reason I’m not satisfied at this point is due to the lack of ATMOS audio.

So am I reading right that the new Chromecast Google TV is capable of playing all DV profiles with MEL and FEL and ATMOS?

No every Atmos...

I can confirm that the new Chromecast with Google TV supports:

Video:
HDR
HDR10
HDR10+
HLG
Dolby Vision Single Track Double Layer in P4, P5, P7 MEL/FEL, P8 profiles

Audio
Dolby Digital (AC3)
Dolby Digital Plus (EAC3)
Dolby Digital Plus + Dolby Atmos
DTS (only with Kodi)
DTS-ES Discrete/Matrix (only with Kodi)
AAC
PCM multichannel (only with Kodi)

Audio not supported:
Dolby TrueHD
Dolby TrueHD + Dolby Atmos
DTS-HD
DTS-X

I don't have an Atmos ready AVR so I can't test too much, I don't know if it could be possible to convert the TrueHD stream to lossless MCPCM or EAC3 and maintain the Atmos layer.

About DV profile 7 FEL I'm now making some tests to determine if it's processing the FEL layer in the right way, but teh first test is passed.
Stay connected...

On my setup chrome cast gave me to most issues, bc off my vertex2,
P8 plays for me but only a few minutes.
But directly into the tv works better.
& plex is the only way on Chromecast?
P5 plays fine of course.
Chromecast cast feel like the vs10 engine
LLDV on it clashes with LLDV on the vertex2
When I use my amplifier u see 24bit 422 yuv as well without the vertex2 another answer that’s it’s LLDV only. Also no forced dv8 rgb from the vertex with that device
Vs10 engine is LLDV from what the vertex is showing

Thanks for the answer Manixx2020beyound
Sorry, but you write in a so telegramically technichal way that I can't understand altogether...

I think you're talking about the test you did before, without the last Chromecast february update.
I agree that the best way for testing is connecting the Chromecast directly to an HDMI 2.0 of the TV.
I have tested samples of every Dolby Vision Single Track Double Layer profile (P4, P5, P7 MEL/FEL, P8) and it plays every of them from begining to end. I have only issues when I create with MakeMKV a new Single Track Dual Layer mkv from a Dual Track Dual Layer FEL mkv file, it's impossible to jump in time, fast forward or rewind. Even if you stops the playback you can't restart from there, the only option is to begin from start, although it's possible to pause en continue.

As I can understand from your words, from your tests you think this Chromecast is an LLDV device.

Well, I wait for news tests with the last february update when you are able to do it. Thanks!

Just finished testing mkv dv version playback Total Recall whol movie playback
Smooth & trigger DV plex ( no vertex) in volved but I can capture which means it’s also LLDV but quality seems better already I can tell diff from the dune.
El is being used but I’ll wait for confirmation
@$50 dollars lol with the dune price I can get 9 chrome cast device lol
I also have no issuses skipping chapters
File plays normally

• Support multi-video decoder up to 4Kx2K@60fps+1x1080P@60fps
• Supports multiple “secured” video decoding sessions and simultaneous decoding and encoding

It has 2 CPUs; Quad core ARM Cortex-A73 and dual core ARM Cortex-A53 CPU, which is probably how it is able to decode a 2160p and 1080p stream simultaneously.

Meanwhile, looking at the S905 spec sheet on page 11 (Chromecast with Google TV is using S905D), you can see only:

• Amlogic Video Engine (AVE) with dedicated hardware decoders and encoders
• Supports multiple “secured” video decoding sessions and simultaneous decoding and encoding

It is also a single CPU: Quad core ARM Cortex-A53 CPU. This probably explains why the Chromecast with Google TV can only decode 5 seconds of FEL, while the Ugoos AM6Plus is fine; it uses the same Amlogic Video Engine and is able to simultaenously decode multiple video streams as well, but is lacking in processing power compared to the S922X.

You're wrong, the new Chromecast with Google TV has an Amlogic S905D3 (https://dl.khadas.com/Hardware/VIM3/Dat ... Wesion.pdf):
● SoC: Amlogic S905D3 Quad Core 4x ARM-A55 @ 1.9GHz (64bit) / GPU Mali-G31 MP2 / 12nm.
● Amlogic Video Engine (AVE) with dedicated hardware decoders and encoders
● Support multi-video decoder up to 4x1080P@60fps
● Supports multiple “secured” video decoding sessions and simultaneous decoding and encoding

I have tested samples of every Dolby Vision Single Track Double Layer profile (P4, P5, P7 MEL/FEL, P8) and it plays every of them from begining to end without stuttering.

The short 5 seconds playback you mentioned just happened with some RESET_9999 samples selfmade, that aren't compatible with my system.

Thanks!, I'm very curious about the picture quality comparison with other devices. I observe a very good image quality, with right light and color treatment and a punchy impression.

Hello, finally I also have tested the Total Recall escene in my Chromecast with Google TV.

Test equipment:
- Chromecast with Google TV updated with february firmware
- Panasonic HZ1000 OLED TV updated with last firmware
- Plex server and Plex for Android TV app beta, updated to last beta version
- Emby server beta and Emby for Android TV app beta, updated to last beta version

As I reported before, none of the samples provided by RESET_9999 activate Dolby Vision in my case, except de P8 MEL test, that shows clearly the compression artifacts.

At the end I have been able to get a copy of the DV version of Total Recall (1990) and I proceeded to test it in the scene at 43 minutes, the spaceship landing.
I created a single track double layer Dolby Vision FEL profile 7 mkv file with MakeMKV.

I have made 3 playback tests and the results are curiously the following:
- Normal playback in Dolby Vision: No artifacts shown!, so it's processing the FEL layer, isn't it?
- Playback disabling the Dolby Vision compatibility in my TV: my TV reports it plays as HDR10 and... don't show artifacts!
- I created a HDR10 version with MakeMKV selecting only de HDR10 layer (NO the EL layer): it shows the artifacts clearly.

It's very curious for me the second case:
- Playback disabling the Dolby Vision compatibility in my TV: my TV reports it plays as HDR10 and... don't show artifacts!

I disabled the tone mapping and any image improvement of the TV but it seems that the Chromecast is still using the FEL layer to improve the HDR10 output, I didn't be aware of this smart behaviour

The image quality of the Dolby Vision version and even the HDR10 with FEL improvement seems very good for me, with no artifacts and a punchy impact.
Unfortunately, as known, the SDR screenshots I did are of no utility because of the wrong colour and detail.
