Correct, but it is streaming, so if you check Stats for Nerds, you will see the audio track is not TrueHD, probably being converted to AC3.  Video is not being touched.

 

 

I'm fine with that. I'm not expecting TrueHD via ARC through the LG app - I'll stream over DNLA to my Oppo for that.

 

But prior to today they wouldn't play at all using the LG app.

 

Now I have the option of watching not on my main system. In stereo in the bedroom for example.

Not sure about the color artifacts.  I've seen some 4K/HEVC video that has some strange artifacts when DirectPlaying on Samsung as well.  I expect that this is an incompatibility of some type.  Does this file play OK via DLNA or USB?

 

For the Commuter, it looks like you are trying to play PGS subtitles.  If they are PGS/graphical subs they will always transcode.  Your only option is to get text subs for the file, or extract them yourself to text files using Siubtitle Edit or some other program (or tun off subs of course :))

Thx for the answer,

About the color artefact, it happens only when remuxing/streaming, direct playing is fine.

Yes it was the pgs subs that caused transcoding.

And it seems DTS can't be streaming/remuxing.

(I've just read the reason " Because anytime we have to remux, we use the HLS protocol, and that doesn't support carrying DTS")!! :D

Glad it's not just me. Looks pretty nasty doesn't it.

 

Also if you view by genres the thumbnails are stretched to be squares.

 

Don't understand, the IOS apps look great.

 

Plex 1, Emby 0 as far as the LG app goes in it's current state.

Yep,

For example when you want to click (with the LG Magic remote and the motion cursor) on a playlist/folder etc... name, you have to put the cursor a little below the text and click there to have it working.

Concerning DTS I made some tests with all transcoding/remuxing options ticked-on: (quality on 4k-120Mbps)

-On a mkv 4k HDR HEVC (main10 104,8Mbps) very big file (81go) I have 4 audio tracks :

-DTS-HD MA 7.1 48kHz 24bit

-DTS-HD MA 5.1 48kHz 24bit

-DTS-HD MA 2.0 48kHz 24bit

-DTS 2.0 768kbps 48Khz

 

To have a smooth playing, emby server will have to direct stream, but there are some strange behaviors:

With all transcoding/remuxing options ticked-off, the file is direct played but buffering/stuttering too much and it is unwatchable (play few seconds, stop, play again etc...) (HDR ok).

With all options ticked on, when I launch play, beginning with DTS-HD 7.1, it will be direct played, then I switch to DTS-HD 5.1 (during playing) then it switches to direct stream (with audio becoming ac3), then switching again to 7.1 and direct stream works again...  When I begin with DTS-HD 5.1 it will direct stream, and switching to 7.1 will keep direct streaming...  HDR working every time.   Strange no??

Direct streaming with 7.1 will be as stuttering/buffering than direct playing. And 5.1 will direct streams smoothly with few little pauses from time to time.

What do you think?

I'm having problems playing back a 4K HDR encode through Emby. It tries to transcode but doesn't play. Plex transcodes and plays, though as far as I know, it's not necessary. I've just put the file on a USB and it plays perfectly straight through the TV.

When I do it through the TV, it ignores the Atmos track and shows the other 3 which work, but in Emby I've already selected the Audio #2 and it still won't play at all.

Hi Luke

 

Attached are the files. I left it a little longer this time and it did eventually play though laggy (probably just my CPU in fairness), but as it's encoded it to AVC it lost the HDR so was washed out.

 

Thanks
