Dolby Vision now possible through MP4 Mux.

[RESET_9999]

what movies have you tried? I can maybe give it a try later tonight if I have it in my library

I tried Joker, Doctor Sleep, First Man, and Spectre.

yep, I think Doctor Sleep EL is not processed. It gives me an error with V1 tool and with V2 tool , EL analyzing stays at 0%.

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%.

hey has anyone who uses MX Player on the Shield Pro tried just starting a video-track only dv mp4, and then pausing, going to menu - audio - open, then choosing your audio.thd atmos file from its folder? curious if this worked the whole time and we didn't have to figure out how to mux it in. I can do this on the firestick 4k fine, but only with dd+ or pcm 7.1 since it doesn't do hd-audio.

[deadchip12]

Well what machine are you playing your videos on?

LG Oled C9 via external hdd.

One question though: Gemini man dolby vision does not play at the correct 60 fps using the original method (remux two HEVCs layers into an MP4 container using mp4muxer). Will it play correctly using the new method (remux two HEVCs layers into an .ts container using yusesope's tool)?

You should try using TSMuxer and just throw the original video file in it and remux to a .ts using this build of TSMuxer: https://drive.google.com/open?id=1Gq5TA ... B1io4OwHW9

I followed your instruction but .ts file does not play on my c9's internal media player.

Thanks for trying that. I tried it again, but still no luck. Are you demuxing the m2ts using tsMuxer?

[shawnc22]

yeah, same tsmuxer version that does the initial demuxing and the remuxing at the end.

[kws53]

With Plex client on HTPC, should I use the TS dual layer or single layer method? Dual layer being easiest...

[yusesope]

I agree on everything except on these statements:

DV streams may have different profiles and configurations.
Single layer: Video + RPU stream
Double layer: Video (base) layer + Video (extension) layer (difference between 12bit and 10bit picture) + RPU stream.

Profile 7 is always double-layer and may be authored in FEL (full EL) or MEL configuration (minimal EL). In MEL configuration the video extension layer contains all zero pictures (no 12-bit data) and could be safely discarded.

I believe that it is not possible to discard anything.
Regardless of the type of EL (fEL or mEL), in the case of a dvhe.04 or dvhe.07 profile, the Dolby Vision Composer accepts synchronized decoded BL and EL video frames and metadata information and uses metadata to reconstruct 12bit Dolby Vision video.

In support of this hypothesis, I took a look at the data in the header of a NAL RPU:

The vdr_bit_depth parameter specifies the bit depth of the reconstructed Dolby Vision video signal.
This is derived by vdr_bit_depth = vdr_bit_depth_minus8 + 8
vdr_bit_depth_minus8 is equal to 4 in both fEL and mEL stream (so vdr_bit_depth = 12)
I leave you the code to analyze the header of an RPU (HERE)

Also, can anyone find a good sample for FEL stream of roughly the same duration - 23 seconds, about 100 MB? Please PM/email me if you have M2TS and I'll produce MKV out of it.

I made two Terminator clips (fEL). I had difficulty cutting the movie so, for safety, I made two clips one of 20sec and one of 40 sec. Find everything HERE
I have not converted the raw HEVC stream to m2ts because I have not followed the events related to tsMuxeR (I have not yet understood why a BL + EL + RPU stream is flagged as dvhe.08).
If someone wants to take care of it, find everything you need at the previous link.

Please try both samples and post the results...

At the moment I can't test anything because I don't have any device that supports Dolby Vision.
My Dolby Vision are a series of hexadecimal codes that scroll across the screen

[shawnc22]

I have not converted the raw HEVC stream to m2ts because I have not followed the events related to tsMuxeR (I have not yet understood why a BL + EL + RPU stream is flagged as dvhe.08).

Is it possible that because it's being flagged as dvhe.08, the EL is being ignored on playback even though the DV flag is triggered? This could explain why somebody previously reported that the credit scene in power rangers did not look like it was in DV even though DV was on. Unfortunately can't do any eye comparison tests on my own as I don't have a DV-capable UHD player either

Could be.
The only profiles that support BL + EL + RPU are 4 and 7 (6 is no longer in use).
mp4muxer should be used for testing purposes.

I am trying to use your tool to create BL + EL + RPU, i have extracted BL & EL hevc streams from my mkv using ffmpeg but the tool always exists out at
BL ANALYSYS: 100.0% EL ANALYSYS 0.0% BL_EL_RPU WRITING 89.8%
i tried demuxing with tsMuxer same result .With eac3to it worked , but the playback after muxing with mp4muxer is very dark and colors are washed out .
Using HDD via USB on B9

[mattmarsden]

yep, I think Doctor Sleep EL is not processed. It gives me an error with V1 tool and with V2 tool , EL analyzing stays at 0%.

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

[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
