BluRay DTS

[QbertMedia 0]

So I have spent nearly 200 hours trying to get BluRay rips to work correctly with DTS Audio. Even using lossless I have the exact same problems. The Audio & Video is completely un watchable it stutters. I even thought maybe my 5 year old Sony ES receiver might be the problem so I purchases a Denon AVR-X3600H and it is even worse. I also had a Roku that I tried with exactly the same results. I upgraded all the USB cables, network cables. I have tried every combination of AndroidTV options and options on both receivers. I have no problem re-encoding the MKV files if that will help but I want to keep the DTS 7.1. I am willing to buy a different device (FireTV, Roku etc) if the problem is with the AndroidTV in the Sony.  I thought that was the problem until I tried the Roku Express+ 

Setup 

TV: XBR-65X750D Running AndroidTV 
Receivers: Denon AVR-X3600H and Sony STR-DA3700ES
Emby Applications: AndroidTv 1.8.28g & Roku Express+ Roku SG 4.0.4

Not really sure what other information you need I have the same exact results with EVERY bluray that has DTS. 

 

Thanks

Somewhere there is a bottleneck, how do you have everything connected? The bitrate is somewhat high, if the network is ok perhaps the clients do not support such a high bitrate.

Ethernet or WIFI?

Can you download and test some of these files added to a library (home library works well)? http://jell.yfish.us/

At what bitrate can you play before having an issue?

Up until today I was only testing on Ethernet. Then I thought since Sony is to cheap to use gigabit ethernet I would try some testing on 5ghz Wifi (router is about 25 feet from TV). I am having the same results with WIFI so I am back to testing on Ethernet.

Test Files : I initially tested the 400mbps file it played fine but I noticed it was transcoding since it was over bit rate.  I noticed that for some reason "AUTO" was limiting us to 80mb (in the android client app) so I changed the setting to 100mbps (which is the highest available) and started testing over.  (Testing all the files listed below)

60-mbps-hd-hvec-10bit.mkv 
80-mbps-hd-hvec.mkv
110-mbps-hd-h264.mkv
120-mbps-4k-uhd-h264.mkv
400-mbps-4k-uhd-hvec-10bit.mkv

So these all play fine. 120 & 400 are transcoding. Something weird I noticed while 100mbps is the highest setting in the androidTV app. When I select 100mbps the stats for nerds shows 110mbps is the maximum. It plays the 110mbps file fine without transcoding. 

One thing to note these test files have no audio. I have no problem playing any Dolby encoded rips (dolby atmos, truehd etc.) it is DTS bluray only (DTS DVD's work fine) This does make sense since DTS has such a high frame rate.

SFN is showing frame rate as 24.42 fps - this is not normal.  It should be either 23.976 for film (likely) or maybe 24/25.

I don't think the issue has anything to do with bandwidth - as you can play the video for 100 Mbit/sec just fine (as expected) - the issue is the DTS mux is not in sync with the video - for some reason.

The Denon Plays DTS (both 768/1500Kbps), DTS-TrueHD and DTS-X just fine - so I know it is not the receiver (I have a Denon in this AV range).. 

This comes down to the rip - have you tried a different example source ?  There are many DTS sound examples on the AV Cinema sites that you could try.

You are not going to get uncompressed Audio via your Sony TV (via ARC) unless it has eARC (but DTS 5.1/7.1 (DTS-ES) should be fine), but there are zero reasons why the Roku plugged into the Denon should not be able to play everything without issues - and if it plays DD/THD ok - then this proves your physical setup is not the problem.

So I downloaded 4 of the DTS demo files. 3 of the 4 severely stuttered and were unwatchable. 1 of the 4 worked fine. So the only one that played through properly was a DTS-HD HRA file the other 3 were DTS-HD-MA and DTS-X files.

Ok I think I am trying to do something that is impossible with a tv that doesn't have eARC. So I need an external emby client any suggestions?

Did you not try a standard DTS file ? 1,536 Kbps ?

This is 'DVD Standard' DTS - and is 5.1 or 7.1 (DTS-ES) and should play perfectly well via ARC.

DTS-HD/X will not play via ARC as the bandwidth is too low - I'm surprised it is even attempting it.   The DTS-HD stream has a standard DTS 'Core' inside it - which should be played when the player/device realises it can't play the DTS-HD stream - this is where I think the issue is - your device is saying it can play it - when it in fact cannot.

DTS-HD HRA is High Res Audio - which is a much lower bitrate - so that may be ok over ARC.

Try the standard DTS files - if they work ok, then this is your issue.  Then we need to find out why your device is reporting it can play DTS-HD when it cannot.

Yea standard DTS has worked fine all along. It is just the DTS HD stuff that wasn't working. I cant believe it took me this long to figure out.

You will need a Shield if you want to passthrough anything higher than 5.1.
