Dolby Vision now possible through MP4 Mux.

The only caveat with this is I don't know if the old player has the same level of dolby vision support as the new exoplayer. I know DV gets triggered and all, but I've never tried doing any kind of picture quality comparisons. You can always get exoplayer to play at 24hz, though, by manually changing the output refresh rate of the shield in its display settings to 24hz.

the google link is to general. when i search for it in the topic i have 30 pages..

just click the first link (it's a pdf) that google shows, and scroll down to page 8.

Well, that could be an interesting test to be performed, even if, at he same time, a blind test done simply with your eyes should be more "ethical" to see if you really spot any difference; at the end we use those to watch

what's the difference between all profiles? (5,6,7?)

nobody?

@kazuma Just go some few pages back:
Profile 4: BL+EL+RPU, SDR compatible
Profile 5: BL+RPU, (Unspecified colorspace = IPT)
Profile 6: BL+EL+RPU, HDR10 compatible
Profile 7: track 1 BL non-DV, track 2 EL RPU HDR10 compatible
Profile 8: BL+RPU, HDR10 or HLG or SDR compatible

[badrobot]

that’s not good for me, because shield tv pro 2019 does not support DoVi Profile 6.

Dovi Profile 6 has been deprecated by dolby.

@badrobot It's already been confirmed that Profile 6 is working on Shield. In any case BL+EL+RPU HDR10 tracks are profile 6 according to Dolby, we just can't have tsMuxer produce non-compliant files with incorrect profile simply because one STB would not accept a profile.

I agree with you.

What I am worrying about is that, plex on shield uses the open source exoplayer, exoplayer does not support profile 6 for now.

And, according to the help information of Dolby’s open source mp4muxer, Profile 4 has HDR compatibility?

Code: Select all

 --dv-profile <arg>                 = Sets the Dolby Vision profile. This option is MANDATORY for
                                      DoVi elementary stream: Valid profile values are:
                                      4 - dvhe.04, BL codec: HEVC10; EL codec: HEVC10; BL compatibility: SDR/HDR.
                                      5 - dvhe.05, BL codec: HEVC10; EL codec: N/A;    BL compatibility: None.
                                      7 - dvhe.07, BL codec: HEVC10; EL codec: HEVC10; BL compatibility: Blue-ray HDR10.
                                      8 - dvhe.08, BL codec: HEVC10; EL codec: N/A;    BL compatibility: SDR/HDR.
                                      9 - dvav.09, BL codec: AVC;    EL codec: N/A;    BL compatibility: SDR/HDR

thnx man! whats the reason to go for each profile? what is the best to take with mp4muxer? i'm using now profile 7 on my LG C9.

[box4m]

Someone wanna help a noob and explain how i get a working .mp4 from mp4muxer that has sound in it? Maybe mp4muxer doesnt do sound? Cmdwindow gets spammed with:
ERR: lost dd sync. resync
ERR: lost dd sync. resync
ERR: lost dd sync. resync
ERR: lost dd sync. resync

If i try muxing it with newest TXMUSER it plays sometimes but sound is chopping up and it barely plays.

Thanks

edit: im using mpxplayer on shield, maybe thats why(?)

[stehohrhase]

Hi guys,

i have create with yusecope's tool and tsmuxer foolowing file:

Dolby Vision, Version 1.0, dvhe.06.06, BL+EL+RPU, HDR10 compatible / SMPTE ST 2086, HDR10 compatible

Is it possible to demux back BL and EL files (for future usage)?

[jcdr428]

What I am worrying about is that, plex on shield uses the open source exoplayer, exoplayer does not support profile 6 for now.

Exoplayer is open source, easy to push a fix to profile 6 if needed.

mp4muxer profile 6 has been removed on 12 Feb 20. The latest document DolbyVisionProfilesLevels_v1_3_2_2019_09_16.pdf mentions BL compatibility with SDR (VUI 1,1,1) only. I've asked Dolby mp4muxer developper on Github to clarify compatibility with CTA HDR10, and whether the document would be revised accordingly.

What is difference between these?

Dolby Vision, Version 1.0, dvhe.07.06, EL+RPU / SMPTE ST 2086, HDR10 compatible
Dolby Vision, Version 1.0, dvhe.07.05, EL+RPU, 8 compatible / SMPTE ST 2086, HDR10 compatible

Both were made from the same DV master - one via the MP4 method, the other via the M2TS method.

[vegitto4]

Hi everyone. Any news/updates about play files with DV on Sony TVs? I have a 49xf9005 and files don't play well (bad colours, much red...) with software players.

Thank you

[tr000]

ah...I see, so these mkv remuxes that still have both bl and el tracks intact are scene releases

uhd disc -> dvdfab bdmv folder -> mkvtoolnix mkv remux

oh yea i get that now, i was just referring to that youtube video posted earlier that showed off the other source . not judging, i’ve done my share of it in the past. out of curiosity though, are you doing that mkv route and including the secondary DV track purely for archival purposes? is the bdmv folder backup not enough?

@tr000, did you run yusecopes tool in -mode 2? that’ll get you a BL+RPU file similar to the dvdfab method that’s meant for profile 5. running the tool without it gets you the EL in its own layer (BL+EL+RPU) that’s not compatible with profile 5. Besides that, yusecope has mentioned in the past that his tool is only meant to be used off of the demuxed tracks from the original decrypted m2ts files. He did not account for any alterations that might’ve happened in the mkv remux process so results will be hit or miss

I did indeed use mode 2. I also was able to get the Blu-ray .m2ts, and the .hevc yusesope's tool made muxed successfully in Dolby's mp4muxer...but it was a garbled mess on my TV. DV data was coming through though, because I could see the TV brightness changing. Very odd. I'll grab the remuxed .mkv again and see what I can do.

Thank you! I ran the command below but the muxer seems to read the whole hevc file in and writes nothing. I end up with a 0 kb output file. Any clues as to what I am doing wrong? I used tsmuxer to extract the hevc files from the original m2ts.

mp4muxer_64bits.exe --dv-profile 7 --input-file BL.hevc --input-file EL.hevc --output-file mp4_dv.mp4

I think you have to wait a bit more. your cmd-line seems right.

The muxer works this way:
1- read the whole file
2- does some unknown work for a couple of minutes ( 10-20 min depending on the length of the movie)
3- then start writing the mp4

Thanks, I let it run for longer and got 1917 and Joker working on my C9. So happy with the results.

Yep, these two films also worked great for me.

profile 6 is out of official guarantee.
shield supports profile 4,5,8

Edit: And profile 8 will also be deprecated very soon. Dolby is cutting all compatibility with HDR10 in favour of proprietary IPT colourspace. This does not mean that these profiles are "out of official guarantee". As far as I know, all SoC reading profile 5 also read profile 8, and all SoC reading profile 4 also read profile 6 as they have similar RPU structure.

My TCL tv plays profile 4 and 5 in DV, it won't do 6 or 8.

This occurs if you're using an Atmos AC3 track. What is your workflow? Where are the files you're putting in MP4Muxer from, exactly?

[Sgt Hartman]

Does any of you got the error message in ffmpeg

bd_open() failed
bluray:: I/O error

while launching ffmpeg -i bluray: D:\your_uhd_bluray_foler\ -map 0:0 -c copy D:\output\BL.hevc -map 0:1 -c copy D:\output\EL.hevc

[mrhollywood]

Forgive me if this has already been mentioned, but if profile 5 is single layer, then wouldn't it work in MKV format without any modifications? As far as I have read the only thing preventing DV in MKV is the lack of handling multiple layers. MKV is a lot for convenient for use over TS.

I've asked Dolby mp4muxer developper on Github to clarify compatibility with CTA HDR10, and whether the document would be revised accordingly.

Answer from Dolby: "Profile 4 is a Dolby Vision specific dual layer format where the base layer is SDR ( BT.1886, ITU-R BT.709, YCbCr 4:2:0) and then the enhancement layer contains the Dolby Vision data. So its is only cross compatible with SDR and not HDR10. That is why the current profile and levels doc was updated to reflect that."
