Transcoding DTS-HD MA 7.1, DTS-HD MA make laggy my REMUX 4K Movies

[FancyNerd92 9]

Hello, i have a lot of Blu-Ray REMUX 4K HDR10+ movies and all they have DTS-HD MA or DTS-HD MA 7.1 audio format.

My setup is:

TV: Samsung Q80A 75" (2021 Model)

Audio: Samsung Q950Α 11.1.4 Dolby Atmos (2021 Model)

Network: ASUS Mesh Network with main router RT-AX88U and hole mesh is LAN connected by CAT6a cable. The TV is LAN connected too.

So when I play the movies they are laggy with freezes and missing .srt subs eventually. What can I do? I have select the bellow transcoding options in my server:

My server setup is:

CPU: Intel Core i7 7700K 4.20GHz

GPU: NVIDIA GeForce GTX 1070 OC by ASUS

Motherboard: MSI Z270-A PRO (MS-7A71)

RAM: 16GB DDR4

HDD: 2x WD Ultrastar DC HC550 18TB

I tried to convert the media but i get a faild in the midle of prossesion.

Here i have and 2 logs from different movies.

Tell me if you need more info!

Thanks a lot!

It looks like you ran out of storage space.

Have you looked at that?

[SamES 891]

Aside from the storage space issue,  there  are lots of comments about this same issue in this forum. 
 

DTS is not supported in these models, the audio must be converted. The issues you are experiencing are common when converting the audio of high bitrate 4K hevc files.   The same issue occurs on LG, it is not unique to Samsung. It’s not related to server, gpu or network performance. The TV does not have a high performance cpu and cannot request and process these formats when delivered in fragments via hls streaming methods. 
 

The recommended action is to play an alternate track that is supported such as AC3. You will lose nothing from a quality perspective as that is what the server is trying to convert to anyway. 
 

if it doesn’t have an  AC3 track then it is easy to add one using ffmpeg. You should be able to find a reference in here on how to add one, or I can find the link for you later

I always have a compatible audio track when using Emby on the Samsung.  I get the same thing converting HD audio on mine and have seen several other posts saying the same.   Usually what happens that I will get a spinning circle and a pause while it buffers a chunk and then it plays for a while before it repeats the cycle over.

siddhartha posted a ffmpeg script that will add a DD+ track if needed.

What deposit of memory must have to working properly the transcoding? I have almost 1TB free.

I know how to add an other audio in MKV files, but I don’t know how can covert the DTS-MA Stereo and DTS-MA 7.1 to another codec with ffmpg. But after all I have a Dolby Atmos 1.200€ soundbar the best on the market and I will play AC-3? What’s the point? What is the best audio codec that I can convert for my equipment?

Your TV doesn't support TrueHD or DTS so Emby has to convert these audio codecs to something your TV does support in order for you to hear any audio.  That is the downfall of using an app which runs on your TV.

If you look toward the back of your user's manual you will see a chart of what your TV does support like the one in the link below.

2021 TV Video Specifications | Samsung Developers

 

As you can see not only is DTS not in the chart of supported audio formats, but there is also a huge comment to "make sure other audio tracks can be selected" if using DTS

In my opinion DD+ (at 1536 kbps) is the best audio codec in that chart which is why I posted a link to a script someone created earlier as a second audio track.  It's a whole lot better than AC3 at 384 kbps which you're getting now on the fly

However, if you really want to get the most out of your current TV and soundbar you may want to look at something like a nVidia Shield which is what I use in order to get HD audio like TrueHD Atmos and DTS:X

 

My setup

nVidia Shield >>> HDMI IN >>> Samsung soundbar >>> eARC/ARC >>> Samsung TV

Have a read of this Knowledgebase article. Ignore that it says LG, the comments are the same for Samsung

https://support.emby.media/support/solutions/articles/44001984861-why-does-the-emby-app-for-my-lg-tv-not-play-the-dolby-atmos-truehd-audio-without-transcoding-

[FancyNerd92 9]

Why Emby server have transcoding hardware acceleration only for image and not for audio? Because if i use my CPU+GPU power i can transcode everything... I have hundreds of Blu-Ray movies already and the prosses is painfull for all these stuff... Even the script is kind of buggy... but after all it's for new movies and not for that already you have. Is there a faster or bulkier way to do this or only the process [mkvtoolnix-> out sound-> transcode-> in sound -> close mkv] ?

Just for curiocity do anyone knows why DTS is out of TV devices' industry? Because I read about Sasmung for example that they supported until 2017 TV models and from 2018 until now they stoped? DTS is oldie? Is buggy? why? and after all if the TV manufactors they stoped using it why they kept it in the Blu-Ray industry as main and only audio format?

[FrostByte 5052]

My guess is that LG and Samsung dropped DTS on their TVs due to licensing fees.  The TV itself supports most audio formats found in broadcast and streaming services, and if you want to watch UHD movies then they want you to buy a soundbar which supports UHD movie audio formats and has additional audio channels (most TVs still only have stereo) plus a UHD player. 

TVs aren't meant to play movies ripped from UHD which is just about the only place you will find DTS now.  They would sell a lot less soundbars and UHD players if they included DTS.  That is my theory.

Reasons:

1. Sell more soundbars
2. Sell more UHD players
3. Save money on license fees

I did eveythink said siddhartha and i'm getting this error. Any ideas?

[SamES 891]

Try this link for a single file, it’s for AC3 so it might need a slight tweak for EAC3

 

This will do multiple files if you put it in a batch file

Ya, the other script is using PowerShell which you didn't give yourself permissions to do

Yes it's about PowerSheel, what can I do? The script is it work or is dead nowdays?

Yes prefer EAC3 but I don't know how to modify scripts. Is there anything ready or any other idea?

In PS type

Set-ExecutionPolicy Bypass

 

[FrostByte 5052]

Or

Start PS

Set-ExecutionPolicy -Scope CurrentUser

then type "ByPass"

Where exactly? 

 

$file=$args[0]
$path = gci $file | % {$_.DirectoryName}
$basename = gci $file | % {$_.BaseName}

Set-Location -Path $PSScriptRoot

$probe=(.\ffprobe.exe "$file" 2>&1)

$substream = ($probe | .\grep.exe -E "Subtitle: pgs" | .\sed.exe -E 's/.*(0:[0-9]+).*/-map -0:\1/')
$acstream = ($probe | .\grep.exe -E "Audio: (truehd|dts|flac)" | .\sed.exe -E 's/.*0:([0-9]+).*/-c:\1 eac3 -ac:\1 6 -b:\1 1536k/')

iex ".\ffmpeg.exe -i $file -map 0$substream -c:a copy $acstream -c:v copy -c:s copy -f matroska temp.mkv"
mv temp.mkv ($path + '\' + $basename + '.eac3.mkv')

[FrostByte 5052]

Do you see PowerShell in your apps?

Right click on PowerShell in your apps and choose Run as administrator 

[FancyNerd92 9]

Ok but now I'm getting another error

[FrostByte 5052]

If you prefer this is how you would do it in ffmpeg.  Then you can use @rbjtech script from SamES post above on how to make a batch with FOR loop to do multiple files.

ffmpeg.exe -i input.mkv -map 0:v -map 0:a:0 -map 0:a -map 0:s? -c:v copy -c:s copy -c:a copy -c:a:0 eac3 -ab 1536k -disposition:a:0 default -disposition:a:1 0 output.mkv

Would be a lot easier I think than messing with PS

[FancyNerd92 9]

Yes but I will get AC3 with low quality of audio and I want at least... after all E-AC-3.

I modified the ffmpeg line I posted above and changed it to output eac3 at 1536k.  Try it out on a movie and see what you get. It worked for me  

 

[rbjtech 4289]

Your sound bar DOES support all the DTS Codecs - but as @FrostByte says in his post above (Link),  the issue is your TV (the 'SOURCE') does not - and thus it is not passing them though.  Even if it did and it had eARC - it would be very unlikely to passthrough HD Audio to the soundbar - TrueHD or DTS-HD/X from a TV Application (ie Emby for Samsung)  

The best solution if you want to play 4K with native HD Audio, is to get an Nvidia Shield Pro - and plug it directly into one of the HDMI 'In' ports on the Q950A.  Plug the HDMI 'Out' into one of your HDMI 'In' on your TV.   Load Emby for Android TV onto the Shield.  You will then be able to direct play 4K HDR plus ALL the native HD Audio tracks without issue.  (eARC will not be required, as you are going direct).  You are actually passing the VIDEO from the Shield through the soundbar to the TV.   The only thing missing will be Dolby Vision, but that is a TV limitation, not the Shield.  Note the Shield does not support HDR10+ so be wary of that.

How can i use the script? On .txt and after that renamed .bat and drag & drop the movie on it?
