Just a little feedback on my initial experiments with 4K playback using the Emby LG app.

 

I'm finding some 4K content works and some doesn't.

 

'Sully' 4K for instance will not play on the Emby LG App. It will play on the LG Plex app. Same results for 'Jigsaw' and 'It'.

 

I'm playing UHD rips from my 4K blu-rays made using makemkv.

 

That being said, where files do play I am noticing quality degradation. 'Argo' for instance streamed via the LG app looks terrible (however the server does say it's direct playing).

 

'Argo' streamed via DNLA to my UHD blu-ray player looks far, far better and as per the disc.

 

So as it stands, if I want to watch 4K rips using Emby, the LG app is not up to the job. This may in part also be due to the TV itself. DNLA to the TV also results in reduced quality (however all files do manage to at least play, same as Plex). There could also be bandwidth issues involved. The LG TV does not have a gigabit LAN port.

 

To sum up, the only way for me to get the true 4K (exactly as per the disc) is to stream using my phone or iPad via DNLA to my Oppo UDP203 and then HDMI into the TV.

 

 

TL:DN

Emby LG app plays some 4K (albeit in reduced quality.

Plex LG app plays all 4K (albeit in reduced quality).

Hi, thanks for the feedback.  Could you please provide the mediainfo for examples that play well, play badly and don't play at all and the log files when trying to play these files.

 

Please take note of the audio format of your files.  For TrueHD, this is not supported by the TV so it must convert it somehow.  Currently it will transcode which means both the audio and video will be converted to another format.  This will result in lower quality, at the very least it will drop down to 1080p.

 

In the next release, it will DirectStream these files, so it will only convert the audio and there will be no loss of video quality. 

 

I'm taking a guess here but I suspect this is your problem.

Looks possibly a True HD issue (DTS-HD MA plays).
 
​The quality degradation on the movie that does play is repeated on Plex so I don't strictly think it is an Emby issue.
 
​Whilst all files do play in the LG Plex app it is far from ideal - some buffering and occasional blockiness. This I believe to be down to bandwidth and the lack of gigabit ethernet on the TV.
 
I'd like to keep the HD audio (I have a 5.1.2 Atmos setup) so it makes sense to use an iPad as a remote and go DNLA to my Oppo, into the receiver and out to the TV.
 
Appreciate the very speedy response :)

A little more experimentation.

 

'Warhorse' - 1080p file with high res audio.

 

Again - image degradation when played through app. Quality as per disc when played via DNLA to Oppo. Server states 'Direct playing'

I think the next version with HEVC streaming will be an improvement for you.

 

vc1 video and PCM_S16LE audio are not enabled for DirectPlay, so if you can confirm that these files will play via DLNA or from USB we could look at adding them.

 

I think that covers most of the files.  There are one or two there that surprise me, Warhorse and Argo should work,  but the others make sense, mostly due to the TrueHD audio.

Apologies. Correction - Argo does work in the app (albeit with reduced quality video). Warhorse does not work in the app.

Hi,

 

On a LG 2018 Oled 55c8, to direct play hevc 4k hdr mkv files I need to tick-off all transcoding option in the emby server user menu. If not I loose the HDR.

When you say the next version will allow to stream hevc, do you mean that I will have to tick-on the transcoding options, or it's better to leave that off as the 55c8 can read hevc files?

Thanks in advance!

Just re-ripped War Horse with the standard audio. Still won't play in Emby LG app, IOS apps or Web app.

 

Plays in LG Plex app. Plex IOS apps. Plays streamed to the Oppo.

 

You guys don't like Equestrian films or something?  :D

That's different and unrelated. We're seeing some situations on MacOS where it doesn't' appear the server has permissions to execute ffmpeg, and we're still trying to chase that down.

Hi,

 

On a LG 2018 Oled 55c8, to direct play hevc 4k hdr mkv files I need to tick-off all transcoding option in the emby server user menu. If not I loose the HDR.

When you say the next version will allow to stream hevc, do you mean that I will have to tick-on the transcoding options, or it's better to leave that off as the 55c8 can read hevc files?

Thanks in advance!

 

You will set it back to defaults, all options ticked.  The client/server will then determine the best playback option, which will include DirectStream for HEVC once it is enabled.

 

Having said that, if the audio, video, subs, container and bitrate are all compliant, it should DirectPlay 4K with HDR with the current version.  Matthew Binns issue is that TrueHD is not supported for DirectPlay, so in that case DirectStream is the next best option once supported.

 

If you do not have TrueHD audio in the file, then it should be able to DirectPlay and you should not be losing the HDR

Magic Mouse can't select headings on main screen (Movies, TV Shows, Music) etc.

 

True HD titles still not working.

 

The whole thing looks decidedly low res on my screen. Has the resolution been altered?

 

War Horse is now playing though.

 

Se7en and No Country for Old Men still not playing.

Hi,

I installed the 1.07 LG Emby app but I have the same problem on 2 mkv hevc 4k hdr files.

-1st "Baby Driver", the file is direct-streamed, hdr ok but I have some strange color artefacts that alternate with a normal image quality. 2 audio tracks DD5.1 and TrueHD, sound is played ok with both tracks.

-2nd "The commuter", the file is transcoded and plyed in a very stuttering way. No hdr.  Same 2 audio tracks played ok.

 

When I tick-off all remuxing and transcoding option everything is ok (appart image based subs not played).

 

Here are the logs:

 

 

ps: yes the whole interface on LG Emby app seems to be lowres now.

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.

TrueHD won't work. Firmware update is supposed to allow HDMI passthru for some OLED models, but not through the TV speakers.  The app has no way of knowing whether the receiver supports TrueHD, so this will always be transcoded.

 

We need to add vc1 video and PCM_S16LE audio (probably next release) for Se7en and No Country for Old Men.

 

I know what's causing the menu selection issue, we can fix that.

 

We're investigating the res issues.

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 :))

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.
