Dolby Vision and 1.15.1

[steffenmanden]

Hello beautiful people!
Just a small update: I revised my code (Exoplayer) after the release of version 1.15.2.
@shawnc22 has just tested (on the new Shield) an apk that i have prepared.
The mkv test file is played correctly and Dolby Vision is successfully triggered.

In the next few days I will release a test version of my apk here on the forum.
At the same time I will try to understand how the h e l l GitHub works in order to be able to review the code together with @shawnc22 and @steffenmanden and present the finished work to the Exoplayer team.

That is great news, yusesope!

For the Exoplayer APK, does this replace the version used by Plex on the Shield 2019?

Plex doesnt use Exoplayer in a huge way, its more for media playback support. So they would have to make their own implementation. However the implementation should be fairly simple as it is pretty much just reading data and them throwing the values to the Dolby Vision playback, which they already have in.

Are there any plans to improve the audio support within MakeMKV for obfuscated discs? I'm currently waiting for the MKVToolNix and Plex update to make my Dolby Vision backup of Apocalypse Now Theatrical. MakeMKV produces noticeable breaks in the TrueHD and when I try and run the TrueHD demuxed by DGDemux through TSMuxer it detects overlapping frames and removes frames resulting in the same breaks in the audio. The DGDemux TrueHD is fine when muxed with MKVToolNix but currently that results no Dolby Vision.

I will be using MakeMKV for non obfuscated backups when everything is updated but with the current status of obfuscated audio in MakeMKV the TrueHD of most obfuscated discs will have to be demuxed with DGDemux or the MLP tool from GitHub first then remuxed with MKVToolNix.

Amazing news, thank you

Hi, in any of this has there also been any advancement in thd+ac3 core support in MKV?

I have a SHIELD question. When I made all my TS files I made them profile 4. Now MakeMKV is ripping them to profile 7. Is the SHIELD going to be able to play those?

EDIT:

What I mean is this....

ts: Dolby Vision, Version 1.0, dvhe.04.06, BL+EL+RPU
mkv: Codec: MpegH HEVC Main10@L5.1 (dvhe.07.06 BL+EL+RPU FEL)

Yusecope has mentioned in the past that he thinks when the Shield decoder encounters an unsupported profile (7 in this case), it will look at the raw video stream and fallback to a similar supported profile for playback. From testing with TS files in the past, the same video stream when stored as either 4 (supported), or 6/7 (unsupported) all work without issue and produces the same image. The mkv's I've tried so far from 1.15.1 and 1.15.2 all have worked despite being labeled as profile 7, so it does seem like profile labeling is not that important as far as the Shield is concerned. Now that @RESET_9999 has found a workaround for the red push issue, the last bit of mystery is to just determine what exact the Shield is doing when playing FEL titles

What do u mean they have worked? How do u know?
When ive tested mp4 or ts profile 7 play as hdr.

I have what I’m sure is a very newbie question from someone just discovering this wonderful tool.

When I open a DV disc, 2 of the titles will show as the main movie. Does it matter which I choose to use for the mkv?

Thank you.

[Woodstock]

That depends on the disk in question.

[Twister20]

If I used DVDFab to backup a UHD disc to an .ISO, can I use MakeMKV 1.15.2 to make a MKV that now has full DV + TrueHD/Atmos content?

Yes you can.

Is there still an issue with playback of single layer vs. dual layer DV rips on players such as the Shield 2019? I realize players like Plex still need to be updated for the new MKV DV format spec, but once that happens, are there inherent limits of the Shield 2019 we can't get around?

Could you elaborate a bit if you don’t mind

If you use mp4muxer to create a profile 7 file with a BL+EL+RPU track from yusecope's tool, it will work and trigger DV in Plex on the 2019 Shield. The mkv DV tests have been done with the modified exoplayer apk that yusecope is developing and will be releasing soon.

The issue with the Shield has always been not being able to play dual-track DV rips. Dual layer rips when combined into a single track works (whether or not FEL titles are being played correctly is still a question, however). None of the Shield's native capabilities are changing with the implementation of the new mkv standard, it's merely a more convenient container.

Disney disks usually have 2 or 3 versions of the same feature, differing only in the language displayed in the title and credit screens. You could choose either, and the DV would probably apply equally.

Throw the mess Lionsgate makes of disks into the mix, who knows what would work?

First of all, many thanks special to mike who made dv possible in mkv files. well done. I'm still a few days away and I'm looking forward to testing everything when I get back.

If PGS subtitles with Plex would be possible that would save a lot of time in muxing. If I understand and remember that correctly, the copy function for TrueHD including Atmos is still missing. (I didn't try DTS:X at all, since the tsmuxer was used anyway) Means I would currently need another tool to insert HD sound !? I've only been at MakeMKV since the last version, because I used the monkey and the mp4box before. At the very beginning of the topic dv i had to use the dolby muxer from github. A lot has changed since then and we are close to perfection. If dv, all hd sounds and natural subtitles are copied in one step, i would "reward" the work with a makemkv license. Thanks again!

Thanks again to yusecope for your work and support on dv. I'm looking forward to testing your apk.

As far as i am aware, Makemkv saves all hd audio just fine?

OK thank you for the info. then the problem was obviously with me. I've only tested it once with sound. Otherwise only the video is copied. Before that, I added the sound from the mpls in tsmuxer 04.06 fix. if that is correct and everything works wonderfully, I said nothing! When I get back I will look for my mistake and of course keep my word.
