Dolby Vision now possible through MP4 Mux.

Are you sure these tvs can play FEL correctly? Some people on reddit say if you watch FEL title with internal player, it is downgrading to MEL.

Proof that they are wrong: You can clearly see the 2 différents layers on my C7.

Question:

Is is better to demux - mux with yusope’s tool, or with makemkv? In term of quality. .
I saw somwhere that makemkv as thw tendensy to ignore nals.

Is there a tool like yusope’s one …that does all what this tool can do and more?!

To get good dv p7 quality on my c1, I need to send stdl (ts or m2ts) to the native com.droidlogic.videoplayer’ player on ugoos6b .

The difference between the native player , and orher player like vimu etc.. is night and day

[mulucy]

Did anyone upgrade the Sony X700 to the latest firmware?

How do you send video to the native player exactly?

Hello everyone! Immediately I apologize, I do not know English and I use google translator.

I need to replace the audio track in the mp4 file with Dolby Vision Profile 5.
I used this program (https://github.com/DolbyLaboratories/dlb_mp4demux) to extract a .h265 video track from a file.
I used this program to create the file - https://github.com/DolbyLaboratories/dlb_mp4base.
Used this command:

mp4muxer.exe --input-file track1.h265 --input-file track2.ac3 --media-lang eng --output-file 00000_P5_f.mp4 --output-format frag-mp4 --mpeg4-max-frag-duration 2000 --dv-profile 5 --overwrite --mpeg4-comp-brand mp42, dby1, iso6, isom, msdh

But I get Error: rap distance larger than max fragment duration

If you do not use fragmentation, the file is created normally, but I cannot use rewind when watching it on tv.

Help me please.

I have the x700 too, didnt update but i read some internet issues plus i dont see any benefit so why the risk to lose/block something? I wouldbt update if i was you.

That's exactly how I feel, tbh. I won't update it for now. Mine is not connected to internet and it has been rock-solid with most remux and DV files.

This is incorrect if the display maps the colors and dynamic range as it should. If it doesn’t that’s on the display you’re using, not the player.

Colors within any of the color gamuts will be completely identical whether they be Rec709, DCI-P3 or BT2020, up to each of their limits of course. So putting a Rec709 source into a wider P3 or BT2020 container should look and display identically when the gamuts are mapped properly since Rec709 is smaller than either of those wider gamuts. It’s not supposed to stretch the colors at all and if it does then your display is doing it wrong, not the source.

I have both an X700 and an X800M2 as well as an AppleTV 4K and they don’t have any of the issues reported with my displays because they map the signal correctly.

Forgot I even wrote here, but you are incorrect. It won't be the same, even if the color mapping is done correctly, the profile settings of the TV are completely different from an SDR profile. Also, from it's not "supposed" to stretch the colors to how it actually works, it's a long way. Even if does work as you think it "should" work, you still have maxed out brightness settings and all, as the TV is running under a DV settings profile. So yeah, it's still crap and sad to not be able to make the player recognize DV content automatically like all other players from other companies do. But then again, it took Sony years to get DV sorted out for their TVs.

I am not incorrect.

Hello! I used yusesope tool for demux an mkv file created with makemkv
I am trying to use dlb_mp4base to generate an mp4 file, but the program creates an empty file
"mp4muxer --dv-profile 7 --input-file bl.hevc --input-file el.hevc --input-file audio.ac3 --media-lang eng --output-file test.mp4"

If your getting the 2 layers correctly maybe you are not waiting enough for mp4muxer....in my flintstones laptop a movie can take up to 3 hours till the mp4 file goes from 0kb to something, then like 3 more hours till its finished.

Also you can try with tsmuxer or Useac3to tools to demux and check if your getting the same (hevc/h265) layers.

from the task manager it is clear if the muxing is in progress
I think the problem is in the demux, because from tsmuxer I only get a video track

your getting 1 file with tsmuxer cause, if its a dv file, it must be a dual layer single stream, instead of going for the mp4 way just use tsmuxer to convert that original mkv into ts/m2ts and ull be able to play it fine as dv.

Yes I had already tried using tsmuxer "Blu-ray Folder", but it doesn't work on my sony x700

Why are you converting to bluray folder, convert to ts/m2ts

usually, with a full blu-ray, I always convert to Blu-ray folder

you said your working with a mkv, then convert to m2ts and play it in your x700

now I remember, I started using Blu-ray folder to be able to change the look of the subtitles.
With a ts / m2ts file, subtitles are terrible.

Can anyone help me how to use dlb_mp4base to create an mp4 dolby vision file that I can rewind on my LG C9?
