Dolby Vision now possible through MP4 Mux.

[shawnc22]

I just tested out some files on LG E9 tv using the internal plex app, using the nvidia shield as my streaming server. I tested it with nobody and john wick which are FEL dolby vision movies.

1. I tried 3 different mp4 05.06 BL+RPU made with (DVDfab, yusescope 0.0.3, and yusescope alfa 0.0.4) - They're all playing but with a dark layer strip at the top, (not sure why this is happening)
2. mp4 dual layer dual track 07.06 is working with full dolby vision no issues with image
3. mp4 dual layer single track 07.06 BL+EL+RPU is working with full dolby vision
4. mkv single track dual layer 07.06 BL+EL+RPU is working with full dolby vision

thanks for your info @shaw, everything you mentioned in your first paragraph is basically correct. I was wondering why yusesope's 0.0.3 tool is making a file which is approximately the same size as the BL alone when I convert it to BL+RPU and so dooes DVDfab. However, if I use his 0.0.4 tool, his BL+RPU is approximately the same size as the BL+EL+RPU but a little bit less which makes me inclined to believe his 0.0.4 tool is the one which is working correctly to make BL+RPU files.

@harpervision. Ah thanks mate, that makes sense too! so anything we stream such as netflix or game in dolby vision is going to be BL+RPU? so it's missing the EL layer? makes sense why netflix movies don't ever look as good as the oppo

Why are you trying to make BL+RPU profile 5 files from UHD disks? Most devices that cannot process the EL will simply ignore the EL if you feed it an FEL title. Profile 5 and 7 are in different color spaces, and there are no tools out there (including the ones you have mentioned) that will convert one from the other. If you simply discard the EL and relabel the profile from 7 to 5, you are left with profile 5 video with its contents in a different color space, and during playback, you will likely get color issues.

Any DV content from streaming services (Netflix, HBO, Disney+, etc) is going to be in single layer BL+RPU profile 5, but this doesn't automatically make it inferior to dual layer profile 7. It all depends on how the BL was mastered. Also, the reason why your netflix movie don't look as good as a disk on an oppo is probably more due to the bitrate than anything else. The bitrate of an UHD disk can be anywhere between 3-5x that of a netflix 4k title.

The reason why I'm doing this is to just test the full capabilities of all my devices. On the shield, all the files I have mentioned above play perfectly on plex in dolby vision apart from the dual layer dual track .mp4 which plays in HDR. They all look v similar to the original UHD disc playback. They all also play on my oppo fine as well, albeit a trick is needed to play the 05.06 ones or I get vertical weird lines across the file ( see above I posted a video of it)

There is no way possible to change an original profile 7 file to a profile 5 file? Isn't that what a lot of people in this long thread have been doing? I recall for the reason to play on the likes of apple 4tv etc? DVD fab seems to be doing exactly that, you feed it a UHD disc and it pops out a single layer mp4 05.06 or a double layer dual track 07.06. Ah I see, thanks for the explanation.

I basically want a file which can play on my oppo and shield in dolby vision and yet to find a reliable one. the .ts and .m2ts single track dual layer 07.06 files seem to be hit and miss. They work on the film nobody but john wick doesn't play at all which is strange. They're both FEL titles

Yes, people have been converting profile 7 to profile 5s for use on appletvs and other devices through dvdfab or some other method, but that doesn't make it an accurate conversion . A true profile 7 to profile 5 conversion requires a colorspace conversion at the very least (nevermind trying to merge the EL data into the BL), and that simply just hasn't been attempted at this point.

As for creating a file that works on the oppo and Shield, my advice would be to just keep full disk backups for your DV titles and only rip non DV titles to mkvs. This way, you can watch the DV titles on your oppo and the hdr films on your Shield. I was in the same boat and eventually just figured that since I'm never going to use the Shield to play back a DV rip anyway, I have no point in creating DV mkvs.

ah thanks for all of the info bud! I don't particularly mind doing that. However, I just don't like leaving things without understanding the fundamentals. I'm just confused why .m2ts and .ts files single track dual layer for "john wick" don't work on the oppo but "nobody" does when they're both FEL titles. Anyway guess some things you just gotta accept

What am I doing wrong? DV is not triggered when playing MKV files via Plex and Shield Pro
TV: Sony 900H (supports full DV profile)
HDMI3 - set to DV

Plex Player: Shield Pro (2019) using latest Plex App. Hardwired to AX86U router using Cat6 via switch.
Tried 2 different resolution settings - 4K 23.976 Hz and 4K 59.940 Hz

Plex Server: On a desktop PC (hardwired to AX86U router using Cat6 via switch) and library also on a HDD with movies ripped using latest MakeMKV 1.16.3
Receiver: Denon X3300W (2016 model and also supports DV).
All cables are Monoprice Premium Certified HDMI cables

Media Info for the movies mention the HDR format to be DV dvhe.07.06, BL+EL+RPU

Example movies. LOTR, Indiana Jones, Black Panther, Matrix.

How are you verifying this? Just because a FEL title plays back on a device (and throws up a DV badge) doesn't mean that the FEL info is actually being used (the device could simply be ignoring it). As far as I know, the only way to verify true FEL capability of a device is with the various FEL test files out there.

Might be my confusion of the semantics a bit. LLDV and Player-led DV have been used so interchangeably in other places that it can get a bit confusing. If LLDV is truly just another way of referring to profile 5, then my fault. What I really was referring to is that Player-led and TV-led DV has nothing to do with profiles.

No, you had it right the first time. LLDV = player-led and is not limited to certain DV profiels (if It was I would not be able to play P7 since my TV only does LLDV and I have verified full DTDL P7 FEL support with the FEL test files).

It's strange because on my LG C7, all mkv 'BL+EL+RPU' are playing as HDR10 video.

Same with B8. Plex app on LG does not support Dolby Vision in mkv container yet.

When I said fully working, I meant physically fully working. Ie. no stuttering, no vertical lines, no distorted colours as such. I'm not sure if they're playing FEL or not. Does the LG E9 support FEL through plex?

and @ NICE and Daddy. Ah I may have muddled up this file with the .mp4 single track dual layer one if both of you are having issues. I'll try again tomorrow and update this message.

EDIT: my apologies! single track dual layer .mkv are only working on shield plex in dolby vision and atmos. I must have got them muddled up as I played about 12 files in the space of 5mins. I'll update my original post.

I'm not even getting atmos on single track dual layer .mkvs on the interal plex app. It's transcoding to ac3, are you guys getting atmos?

Most streaming boxes on the market that are capable of playing DV MKVs (Shield, Zidoos, Dunes) can only in reality play MEL titles. These boxes lack the secondary video decoder needed to fully process an FEL title. When these players encounter an FEL title, they will simply ignore the EL and just apply the RPU dynamic metadata to the BL. Whether this is a "waste of time" is up to the user. RPU applied to just the BL is still superior to normal HDR10 and for certain titles, even the FEL doesn't really contain that much image data. There are reports of a few streamers that are capable of fully processing FEL titles (the new google tv chromecast and some chinese Amlogic S922XJ-based boxes), but their limitations have been well documented elsewhere in this thread.

It's better than normal HDR10, because normal HDR10 is not dynamic, you are only missing the 12 bit information that is stored in the El layer

So to someone who is not too in depth with the technical lingo, is it better to have a BL+RPU file playing dolby vision than a HDR movie? I think shaw mentioned that messing with dolby vision profile 7 movies and making them into 5 is a bad idea. Is it possible to make a BL+RPU profile 7? I think tsmuxer makes it automatically to profile 8 if you insert a BL+RPU hevc file

Yes, most of the time it is. There are some edge cases such as Saving Private Ryan where if you don't use the EL and just apply the RPU to the BL, you'll get bad flickering throughout the movie. In such cases, it's better to just go with the HDR10 only. But unless you have a device that strictly requires BL+RPU and won't even play a file with EL, then just don't do anything different. If you have a profile 7 BL+EL+RPU file and play it on a Shield or Zidoo device, it'll just ignore the EL on its own and play it as if it's just BL+RPU; you don't have to manually remove the EL during the muxing process.

Hi,
This is my first post, I´ve been following this topic from time ago, but this weekend I finally started to put hand on building playable DV files on my LG B7.

I tried to find an answer to my problem all along the topic, but no luck.

Everytime I used mp4muxer (any version) I get an empty (0kb) file, and I cant figured out what Im doing wrong.


In image you can see the files Im trying to use (BL, El and ac3) and the command line

what Im doing wrong?

thanks!
Walter

[DaMacFunkin]

The reason you have a 0kb file is You need to wait for it to finish, it can look like nothing is happening but depending on the speed of your system plus the size of your file it could be 20 - 40 mins before the file finishes outputting.

Thanks for your comment.
wait for 1hs and still 0kb. Tested using differents disks and the same 0kb output.

After writing the command line, as soon as I press enter, the output file is created and in cmd its appear the line referring to a disk/folder (in my case H:\DV Test>)

but nothing happens, should I see some command/instruction like "%counting" or something denoting mp4muxer is working?

Thanks
