Dolby Vision now possible through MP4 Mux.

My understanding is that although the ShieldTV 2019 is capable (hardware-wise) of TV-led DV, the AndroidTV OS only supports LLDV playback and as a consequence the FEL is ignored.

FEL requires two decoders which the Shield (and most other non-blu-ray players) don't have. That is why the Shield cannot play FEL. Has nothing to do with Android version or LLDV. If that was the case I would not be able to play FEL on my system (X800M2 w/LLDV only TV that plays FEL just fine).

Just got a Zidoo z9x player.. works great for any file I played but tv-led has the wrong bt2020 flag as well SMH

The x700, the Shield, the appleTV, the firestick, Chromecast, Ugoos:



colors are mostly accurate, still have to check DV but at least there is no red push on Doctor Sleep. if they fix the bt2020 flag, it is a better device than the Shield IMO

HDR10 422 12bit
zidoo vs source vs htpc: https://slow.pics/c/sjhJStHn

SDR 422 12bit (444 8bit is the same accuracy):

When is the BT2020 flag supposed to show up? Only when using LLDV mode?

in tv-led, the player sends a raw DV signal in an RGB 8 bit container (at this stage the video has purple and green color just like profile 5 look on an sdr screen so its not in bt2020 PQ yet).
Then the TV does the tone mapping and the picture, in the end, is 422 12bits bt2020 but only in the TV , not supposed to show up before (in the chain with vertex and player).
in lldv, the player does the tonemapping so the signal that is sent to the tv is already 422 bits bt2020. That is also the reason why @manix can capture it with his shogun atomos but cannot do the same with tv-led signal.

Explains why I see BT2020 for all DV with my TV (LLDV only).

You have to check the pattern in the complete dark. Let your TV warm up for a couple of minutes and also let your eyes adapt to the darkness.

64 is completely black and you won't see it flashing unless you have raised black levels. You should see flashing starting at 66 for ideal shadow details. 65 is almost impossible to notice.
The problem with the C8 ( and CX/C1 from what I can read), is that it starts crushing black at 72ish in DV.
HDR10/SDR levels are correct, I can see 66 flashing.

Finally got around to checking this. I had raised blacks for all 3 of my sources (X800M2, Apple TV 4K gen2, madVR PC all connected directly to TV via different HDMI inputs). The PC w/madVR was way off (decreased from 50 to 33 on the black level adjustment setting). The other two were dropped to 47. On my TV, black level adjustments are available per HDMI port but all the modes (SDR/HDR10/DV) share one setting per port so which test should I use when checking? On the X800M2 I never watch SDR or HDR10 so that is any easy one just use the DV P5 test. On the Apple TV I watch mostly DV (Netflix) with some SDR (YouTube TV so I don't really care how accurate it is there) and HDR10 (Amazon but not much at all) so I used the P5 DV test for that device too. For madVR I used the P8 test (for the HDR10 fallback since madVR doesn't do DV). I watch as much SDR as I do HDR10 on madVR but figured it was more important that the HDR10 mode be set as accurate as possible due to the increased color range HDR brings? Note: my TV was never calibrated - professionally or otherwise.

If you mux a ST-DL hevc stream using dolby mp4 muxer as p7 (even though just one input video stream, no problem, still spits it out) you can then play ST-DL DVp7 from an mp4/m4v on CCwGTV, SHIELD TV 2019, and the Hisense 50U6G Android TV I have.

Hello! Sorry if this is a dumb question. I have an mkv file with both DV and HDR10+. This triggers dolby vision on firestick, but only shows a black screen. How do I solve this? Should I remove the HDR10+ metadata? And if so, how?

Thanks!

This is from Sony's website Sony X700 owners:
Firmware update version M43.R.0284 for UBP-X700 | Release Dat 08-24-2021

• Removes the Gracenote function
  Improves HDMI connection stability
  Supporting Dolby Vision content for Blu-ray Disc, Netflix and VUDU
  Supporting online streaming services

Have not updated mine yet. Whatever DV support means in the text above. Maybe they fixed the DV limitation where you had to know which movie/disk is DV to manually enable it?

I would suggest using the Kodi Dolby Vision builds for this, since it's patched to skip the HDR10+ when Dolby Vision is also present.

Otherwise, you can try this script: https://gist.github.com/quietvoid/175d7 ... 9eb1bd2c38
Which is based on yusesope's script, so it requires python and runs like so:

Code: Select all

python hdr10plus_remove.py -i source-video.hevc -o output-video.hevc

Yea but nitflix & vudu as well so it might be more than just movie/disk is dv,
Well only 1 way to know,
I updated mines a week ago but haven’t look closely at any changes.

Yes, that script worked for me like a charm (Oppo has issue upconverting hdr10+ to DoVi), thanks.

Oppo has issue upconverting hdr10+ to DoVi

why would you do that now that there's a tool that perfectly converts HDR10+ to true dynamic DV?

Is it possible to remove Dolby Vision from certain scenes/frames only via RPU editing before 'burning' into BL HDR10 hevc stream to make P8 converted file?

Reason I'm asking - I burn forced subs only into the main hevc stream. This way I don't have to worry about for these 'integral parts' the sub format support of what/where I'm watching, subs kicking in or not when they are or are not supposed to, etc etc

When burning them in before making the DV file, the DV overlay gives them a rainbow effect (dunno if discovered before or not, can't be asked to read back 10,000 pages just for that TBH). Burning it in afterwards obviously isn't a choice cause of DV IIRC, correct?

It's not a dealbreaker, nor that distracting TBH, but just wondering if removing the DV from just these scenes/frames/parts via the RPU if possible would giver better overall effect when watching and subs appear on screen (might not also, if I don't remove it from the whole scene/setting for where subs appear might be too distracting seeing the same scene with DV then suddenly without- but have to see first right?)

Obviously sep subs would work but trying to see if way around that for reasons I explained above first (if I even resort to that, like I said it's not too bad really)

why would you do that now that there's a tool that perfectly converts HDR10+ to true dynamic DV?

You had to manually input (change?) some info into the json, right? Or was the entire thing fully automated? I have some HDR10+ only titles that I could make DV versions for. Shaun of the Dead and American Gangster off the top of my head.

yes, everything is pretty much automated. I just adjust the l5 active area and the l6 metadata but I don't think it really matters so you could probably just ignore it.
I watched two HDR10+ to DV movies and both were perfect.
