Dolby Vision now possible through MP4 Mux.

[powdeau]

The mp4 file plays fine on my LG C7 and even the DV logo is displayed. Is it possible it could work or do I just get some sort of fake DV?

I don't know. You could try remuxing the file here: viewtopic.php?p=113537#p113537
In the same way, if you see changes then it should probably work.

Yes! I can see the changes.
Thank you for your help!

What's up with the new Firetv stick? I don't know if it was the same with the older one but here's what I'm noticing:

1- no 24fps support on plex ... 23.976fps is fine
2- if display settings are set to '' AUTO 4k max '' then everything that is not 4k plays in 1080p on plex. (no upscale to 4k )
3- if display settings are set to 2160p 60hz, then 1080p videos are played in 4k but then the framerate match doesn't work anymore on plex
4- display settings ''AUTO 4K max'' , 4k movies on iTunes/appleTV plays in 1080p
5- display settings '' 2160p 60hz'' , DV movies play in HDR10 4K on itunes.
6- frame rate match doesn't work at all on iTunes.

in fact , it looks like only the amazon prime app works properly. I don't have a Netflix account.

1- I played a 1080p24 file and Plex matched it to 24Hz, confirmed with System X-Ray. HDMI set to 24Hz.
My display settings are set to Auto.

2- Played a 720p25 file and it is sent as 720p50 to the TV.

Are you sure you're matching the resolution as well in Plex?

3- I'm pretty sure not setting to Auto makes the OS hide the different refresh rate modes, it was the same on the 2018 with Kodi at least.

Netflix logged me out so I don't want to bother trying it, but I'm pretty sure it did 2160p.

1- will test another file, but the one I tried played in 23.976fps according to my vertex.
2- didn't try 25fps content (not sure if I even have some) but yes, both firestick and plex settings have the frame rate match on. Resolution match, I tried both but will try again, I'm not sure
3- yep, once you're not on ''auto'', framerate match becomes greyed out.

The Android Plex app has two settings, one for the refresh rate, the other for the resolution.
At least for me.

yeah sorry I misread your post.
Yes, I think I tried the resolution match on and off. but will try again, not 100% sure

[RESET_9999]

ok so I tried with plex resolution match on ... this makes the TV switch to 720p for 720p video but it stays in 1080p for 4k videos ...
So I guess the right setting is ''off '' but still no 4k for non-4k video if the firestick display setting is ''auto 4k max''

Tried another 24fps video and still got 23.976
tried 29.970fps video and got 60fps.



chestnut man 24fps

I remembered I did post about this before: https://www.avsforum.com/threads/offici ... t-61099898
So it's weird for it not to upscale at all for you..

Although I can't remember if I did that test on the new 4K Max.

I have a question regarding encoding a file to 1920x1080p and add the Dolby Vision later. Somehow, I don't get the right file after RPU insertion.

I have encoded a Game of Thrones Episode (4K REMUX, which is Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU). I encoded it without cropping, (which I do for every encode, also movies, I just resize it from 3840x2160 to 1920x1080).

It got me an 1080p episode, which is HDR10. I used the following command to change the .mkv file to hevc:

ffmpeg -y -i GOT.S01E01.mkv -an -c:v copy -f hevc GOT.S01E01.hevc

After this, I use the command to extract the RPU from the HEVC with mode 2:

dovi_tool -m 2 extract-rpu GOT.S01E01.hevc, which gives me an RPU.bin, which, I think should be converted to profile 8.

After this, I use the ffmpeg command to change the re-encoded file from .mkv file to hevc.file. I then usethe following command to inject the RPU into the re-encoded HEVC.file:

dovi_tool inject-rpu -i GOT.S01E01.HDR.hevc --rpu-in RPU.bin -o injected_output.hevc

But somehow, I doesn't work for me. It keeps begin SMPTE 2086, HDR10. Dolby Vision won't be visible in the hevc output file. When I mux the hevc.file to .mkv, then it still is only HDR10, and not Dolby Vision.

What is the part where I screw up? I'm doing it somewhere, but I just can't put my finger on it. Or is it a cropping thing? Some help with this would be very appreciated!

Try running the muxed mkv through MakeMKV

Makemkv is just adding the dvhe flag, in profile 7 and 8 you can do this quickly with a hex editor, it is in the linked to guide on the previous page.

I'm facing a new problem with a movie: Bumblebee (2018).

I encoded the movie to 1920x1080p, the movie itself is DV 07.06, so I just extract the RPU (Shield Pro, so it does play). Somehow, when injected into the encode, and afterwards to .mkv and then makemkv, it is DV 04, which it sees as ''SDR''. I don't know why this is happening? When I extract the RPU with mode 2, I will get a DV 08.03 file. If I use mode 0, I also get DV 04. Does anyone know why this is happening with this movie?

Can you provide the RPU file?
It would be weird for the profile to be detected as 4.

I have uploaded the RPU.

@quietvoid
When I extract RPU from the Enhancement Layer, the resulting RPU length does not match the video length.
Mismatched lengths: video 163840, RPU 128978
This error has occurred in one movie so far.
I can send the sample EL.hevc file if you need via PM.

The EL was probably cut off somehow.
In the past tsMuxer did that, you should try getting it directly from the m2ts with ffmpeg.
I don't need the sample because it wouldn't be very useful unless you're 100% sure it's complete.

Thanks. I can't reproduce the profile 4 issue with MakeMKV.

Regardless of if the RPU is added with x265 or injected, it always shows profile 7: Codec: MpegH HEVC Main10@L5.1 (dvhe.07.00 BL+RPU)
MKVToolNix (v62) also adds the correct block: Dolby Vision, Version 1.0, dvhe.07.06, BL+EL+RPU, Blu-ray compatible

By the way, you shouldn't be reencoding unless the RPU is profile 8.
Because the EL would probably be out of sync, and might not even work with 1080p base video.
And keeping a profile 7 RPU makes no sense without the EL.
