Dolby Vision now possible through MP4 Mux.

[thetoad]

the mkv files mike posted when played on my oppo to my sony x940e, they only comes up as hdr10, not dolby vision.
when I play the dolby vision ts files on LG's website (https://4kmedia.org/lg-amaze-dolby-vision-uhd-4k-demo/) they come up as dolby vision

This could be an explicit container check. Can you please try converting MKV file to TS and see if it changes anything at all.

Code: Select all

ffmpeg -i Joker_BL_EL_RPU.mkv -c copy Joker_BL_EL_RPU.ts

tested, same thing. came up as hdr10 only. I know it can play a dolby vision.ts file as it play the one from LG's site

vlc shows the codec for the one from LG as

Codec: Dolby Vision HEVC (H.265) (dvhe)

while for my ffmpeg copied, it shows

Codec: MPEG-H Part2/HEVC (H.265) (hevc)

I converted the mkv files you posted to ts with tsMuxer, and they both playback correctly triggering Dolby Vision on the 2019 Shield.

So this IS just a container check, and hardware can use this encoding method. We're good!

I too converted your files with tsmuxer. In firestick 4k both files trigger Dolby Vision via Plex app (beta). In emby app they trigger hdr

Guys, please make sure to use the very latest tsmuxer from doom9 (the one that supports EL NALUs) or any version of ffmpeg with "-c copy", in order to preserve all data during container conversion.

Code: Select all

ffmpeg -i Joker_BL_EL_RPU.mkv -c copy Joker_BL_EL_RPU.ts

I made the Joker_BL_EL_RPU.mkv conversion again using 3 methods.
1-using ffmpeg = HDR
2-using tsmuxer latest official version w64-nightly-2020-03-10--01-12-52 = HDR
3-using tsmuxer posted by @Reset_999 https://drive.google.com/file/d/10zOr0I ... sp=sharing = Dolby Vision
Using firestick 4k and plex app (beta).
Emby app gives HDR always.

Here are several clips of 23 seconds each relating to the Joker movie (with the iconic scene that has been discussed HERE on the Plex forum).
You can also find the original HEVC raw streams *** and those obtained with my program (the BL_EL_RPU version HERE, and the second BL_RPU iteration HERE).

I also muxed the Bluray disc with DVDFab and after an analysis with a hexadecimal editor, the file obtained is identical to what can be obtained with my program - second iteration)

If you want to share files on other forums too, there is no problem for me.

• Joker Original BL + EL_RPU raw HEVC
  
  
  • Joker_BL_EL_RPU raw HEVC (my program - first version)

So I just wanted to make a couple comparisons(on the Shield) with the Joker clip that was originally posted. For the HDR only clip, I took the original BL HEVC layer and put that only in its own TS container with TSMuxer. Then for the DV clip, I originally tried to combine the two original HEVC (BL+EL) files using v2 of yusecope's tool, but it kept hanging on me after dropping in the files, so I just used the one he had already created in the post above. The resulting TS file with the BL+EL+RPU raw HEVC file was flagged with the same dvhe.08.06 profile as I've seen with other remuxes. Both files played fine and DV was correctly triggered on playback with the DV file. Here are the results:

As you can see, there is definitely a noticeable difference between the two files (although not as much as the pictures may indicate due to my shoddy camera work). Specifically with the DV clip, it looks a bit brighter with the furnace on the right side more noticeable. I think this proofs that the EL layer might not be completely ignored in DV profile 8 videos? Unfortunately I don't have a UHD DV-capable player to test the actual movie and see what "real" DV should look like.

Yes, in the next version.

But, hopefully, even with current MKV samples we will be able to bug and poke firmware and playback software authors, so they add support for MKV container when they check for the possible DV data. Plex looks like a first candidate to me...

WOW! This is an exciting development. Assumably until that happens (MKV support) we could convert them to TS and we should be good to go? I've yet to get the sample to play in Plex on my 2019 Shield Pro but I'm sure it's something on my end. I tried both ffpmpeg copy and the nightly tsmuxer to convert your samples to ts and couldn't get them to trigger DV. But again, I'm sure it's on my end.

I guess I should have kept reading. Ok, I don't have the TSMuxer version you're referencing in 3 (and the link you posted isn't complete). I guess I'll have to go back and find it. But yes, I got HDR for both ffmpeg and the nightly TSMuxer, as well. As you see in my last post, I thought it was something I was doing wrong but now it makes sense.

I can't understand how is possible we don't have any windows player than can play DV

Only in Android

PM'd one of the guys at Nvidia forums asking about what profiles the 2019 Shield supports and here was the answer.

We support profile 4 MEL (minimum enhancement layer). Also single layer profiles 5,8.9.

There is, it's just restricted to certain (licensed) systems.

This will enable DV in Windows 10 when a video is played through the native app: https://www.microsoft.com/en-us/p/dolby ... ltg1lwphlf - it seems like it supports only single layer profiles like the Shield.

According to this post, this feature is gated by a string in the BIOS that the custom ICC display profile looks for (apparently they had to release a modified version after the BIOS string changed after a firmware update )

https://forums.lenovo.com/t5/ThinkPad-P ... =1#4559914

Not sure if there's some signature that makes sure that string isn't modified or if someone smart with a hex editor can work some magic...

[mattmarsden]

Does anyone know what the specs of the Apple TV 4K are? I presume its the same as I presume thats what the Dolby single layer license gets you.

Yeah, it's easy, paid media player. But this doesn't happen

Powerdvd is a paid media player and they don't have a license for it. Given that, I doubt we'll see it any time soon. I suspect we'll see TVs that negate the need for it before we see it on the pc.

We support profile 4 MEL (minimum enhancement layer). Also single layer profiles 5,8.9.

So anything we mux in single layer can't be FEL (if we want it to work properly on the Shield)? I'm guessing there's no easy way to convert FEL to MEL?

[yusesope]

Of course, EL is always 12 bit on blu-ray. The question is what exactly is in these 2 extra bits. My hypothesis - in MEL stream all pictures in EL are filled with the same value (zeroes). This is easy to verify though - one just has to decode entire EL from any MEL disc (Joker) and confirm that ALL frames in EL are indeed dark zero pictures. From the sizes of slice NALU it looks that way.

I believe you are right.
I have rendered every single frame of a FEL (Terminator) and an MEL (Joker) stream.
It was clear that there were differences between the FEL frames.
The MEL frames are instead all the same (I also tested another MEL layer and after rendering it I get the same MD5 hash).

However, I believe it is appropriate to keep it.
If you notice, several users have reported that the Shield was able to play my files with profile dvhe.07.
There seems to be a fallback mechanism that allows you to take advantage of the profile best suited to the situation (in this case dvhe.04 given the presence of BL, EL and RPU): are we sure that, by removing the information relating to the EL layer, the hardware decoder is not initialized with the specifications of the profile dvhe.05 (BL + RPU)?
In this case, the decoder would expect a 12bit stream with IPTPQc2/IPT proprietary color space (instead of 10bit YCbCr).

... I originally tried to combine the two original HEVC (BL+EL) files using v2 of yusecope's tool, but it kept hanging on me after dropping in the files, so I just used the one he had already created in the post above...

I can assure you that the tool works: the batch file (the one with the .bat extension) starts the program expecting to work with huge files (and not with 90MB files). To combine the two example HEVC raw streams you have to launch my tool using the command line:

Code: Select all

python-3.7.6.amd64\python src\bl_el_rpu_builder.py -mode 1 -lbf 1000 -bl \path\to\Joker_BL.hevc -el \path\to\Joker_EL.hevc -of \path\to\output_file.hevc

I was going to give that a try, too, when I got home, but I can try First Man also. I'm wondering if it might be because the Doctor Sleep disc is also in HDR10+. The EL might be a little different in that case?

That's interesting, I didn't realize it's in HDR10+, though that explains the descriptor in mediainfo. The file did not give any errors in the tool, and it did finish to 100%.

Same with Power Rangers

Whoever had the "EL ANALYSIS: 0.0%" problem could kindly upload a piece of the two original layers

Code: Select all

ffmpeg -i \path\to\bluray\folder\or\m2ts_file -map 0:0 -ss 0 -t 20 -c copy \path\to\BL.hevc
ffmpeg -i \path\to\bluray\folder\or\m2ts_file -map 0:1 -ss 0 -t 20 -c copy \path\to\EL.hevc

We need to wait until next month, for powerdvd20

If not come with DV, possibly we "never" have DV in Pc
