Dolby Vision now possible through MP4 Mux.

Is there someone who tryed the new Dune HD Real Vision 4K ? https://www.dune-hd.com/products/dune-hd-real-vision-4k

It seems to be the long awaited product ...

Playback of Dolby Vision Blu-ray images

The media player supports direct playback of full Blu-ray disc images (BMDV and ISO) in Dolby Vision format (MEL and FEL), even when using full Blu-ray menu. The extended Dolby Vision information is used and transmitted to the TV to improve the picture quality. This is possible due to the unique video playback and output engine created by Dune HD. Other RTD1619DR-based media players do not support this. Dune HD media players are the only hybrid network media players in the world that combine support for Dolby Vision Blu-ray disc images with support for Internet video services and Android applications in one device.

Widest support for Dolby Vision file formats

Dolby Vision is supported for all popular file formats (BDMV, BD ISO, MKV, MP4, TS, M2TS). All popular Dolby Vision profiles (P4, P5, P7 MEL and FEL, P8) are supported. The media player supports the largest number of variations of Dolby Vision file formats of any other media player.

Pretty sure there's no difference between all the other existing Realtek 1619DR based products out there. Dune has done this in the past in that when they mention "FEL support", they don't actually mean they utilize data from the FEL. It just means that the device can safely ignore the FEL, apply the DV RPU data directly onto the BL, and playback FEL content without issue (just like the Shield, Zidoo Z9X, and couple other Dune players). There's likely a hardware limitation to the Realtek SOCs that prevents full FEL support.

What you are saying is can be true. Full FEL support comes from the hardware side. It can't be just implemented on a software level per docs from Dolby Labs. We need to review it and compare it side-by-side with famous FEL DV screens to make sure it does utilize the a stream for proper DV FEL playback.

I believe that FF/RW is not possible on m2ts files over a certain length on the x700...

The only workaround is to use TSmuxer to create a Blu-Ray folder output using the mpls of the main film and place those folders created by TSmuxer in the root of the USB drive...

Very cool, thank you!

Seems like perhaps Dune has augmented the RTD1619DR with other processing "unique to Dune HD media players", if their marketing hype is to be believed (which, you're indicating, it is not)?

Dolby Vision VS10 video processor

The advanced Dolby Vision VS10 video processing engine ensures maximum image quality when playing any type of content (SDR, HDR, Dolby Vision) with any type of video output signal (SDR, HDR, Dolby Vision), improves the SDR/HDR/Dolby Vision conversion quality, minimizes the effect of "posterization" ("banding") due to more advanced 12-bit video processing. This gives benefits even when using the media player with older TVs that do not support Dolby Vision.

...

Dune HD Dolby Vision Purifier

This technology, unique to Dune HD media players, optimizes Dolby Vision files on the fly for maximum compatibility with the Realtek RTD1619DR media processor. This helps to ensure the most stable playback, including incorrectly encoded files (which often cause freezes, stuttering, sound out of sync on other media players).

I'm game to order one, just trying to decide amongst the Real Vision, Pro Vision, Max Vision, Ultra Vision models and considering my use cases...

Thanks, you're right. I just found that post and was reading it as you were posting it here.

So, never mind. Seems like testing of the Pro Vision at AVSForum (same chipset as the Real Vision, with 4GB instead of 2GB of RAM) shows the same problems with the VS10 as the Zidoo boxes and no FEL support, meaning it will apply the RPU, but doesn't render the video from the EL to achieve full 12-bit DV.

Well, this sums up pretty much all the answers and questions. On to the next one lol ( thank you for the link BTW )

[daddy]

Thanks @shawnc22 and @markswift2003 for this great test.

[MOHAX777]

On most movies the Zidoo Z9X will do you fine, if you absolutely feel you need full FEL then Ugoos am6+ with patched Kodi, but it is a real flaky box tbh.

Ugoos released a new firmware today (https://ugoos.com/rc-firmware-update-v0 ... -x3-models), with video codec and stability fixes.
Might be worth checking out. I hope this update is a sign that the rumors about the abandonment of the AM6 are not true.

Update with small fixes, nothing changes with DV in mkv troubles (Kodi 19.x from Kodinerds / fangos): sometimes "ring of death" during start movie (repeating stop/start may help), lags/freezes/glitches for 7-profile (depends of release - some has 1-2 during play, some - every 2-3 sec )

[Mattl0]

Pretty sure it is afr issue. With afrd installed as a system app i do not have these trouble. I also use vimu player.

I just wonder why it is sending 444 to the tv and not rgb for tunneling.

Edit : I was able to capture this from adb . So maybe sending 444 ycbcr/rgb is the same?

[Mattl0]

I am also wondering if my lg b6 can do tv-led since I have not been able to find the info on the web. Everything I have seems talks about lg c7 to 2019 lg oled.

[userr]

Sooo, is there any box/player that can handle FEL correctly that also has ability to connect to a PLEX-server?
Landscape seems like theres a ton of alternatives but all fall short

[bobbymkV]

I laid out some of the FEL-specific issues I've been experiencing on the AM6+ in an email to Ugoos. They replied back very quickly saying they are trying to reach out to Amlogic for assistance as their hands are pretty tied when it comes to those specific DV-related issues. Sounds like a longshot, but maybe a tiny bit of hope left.

True Dolby vision is tunnelled RGB 8 bit - LLDV is 12 bit.
