BUG LG CX When DTS transcoding

Hey guys,

My new LG CX TV which has Plex app built in it, is having an issue when trying to display 4K content under DTS. Since the TV is not compatible with DTS, Plex media server transcodes it into ACS, but then the image breaks:

When using direct ACS language it just works fine. The issue is that my language is just in DTS :frowning:

Can you please fix this?

Kind regards

Hello,

Any update on this?

Kind regards

I think I have the same exact problem My Post

It would be great if someone from Plex team, could address this issue.

Having the the exact same problem. Only getting distorted images when I’m transcoding audio. If I’m selecting a AC3 audio stream, image is fine again. I can provide logs if needed.

Still having this problem on a lot of movies with DTS audio. Is there any fix available?

SSJGoku post indicates he is using a shield server, are el_pedriyo and masi456 also using shield server?

yes a small sample and log files would be helpful from all affected users.

use DEBUG only (NOT VERBOSE)

Easily Gather Logs

Beginning with Plex Media Server version 1.1.0 and newer, it is simple to quickly gather your server logs.

  1. Go to Settings > Manage > Troubleshooting in Plex Web App
  2. Click the Download Logs button
  3. Save the resulting zip file

You can now share the zip file to help investigate an issue you’re experiencing (for instance, by attaching the zip file to a forum post you make about the issue).

Hey,

I’m not using the Plex Server on a Shield, my server runs on a Windows machine.

I got a 30 sec sample ready that can reproduce the problem reliably on my TV.

But

  1. The logs contain a lot of personal information
  2. The sample is from a personal BD rip, it might contain copyrighted material.
  3. Since it is high bitrate content, the whole zip is 350MB big

Is there any way I can send this data to the plex team without making it available publicly?

Plex Transcoder Statistics.log (5.6 KB)

Here is the log file of the Transcoder Statistics for the file, if you need all log files I would send them to you by pm.

I am having the same issues. When audio transcoding, video in 4k HDR direct playing, my lg CX displays the same artefacts as OP’s image. No subtitles enabled. No Shield, utilizing the WebOS Plex app streaming from my powerful Desktop PC (5600x + 3070).

Sometimes, only parts of a movie display this issue, the beginning of Interstellar for example works fine, then the artefacts appear for about 10-20 min, disappear, then appear again later in the movie, in set and reproductible timestamps.

If I choose AC3 for the video files displaying this issue (Interstellar and Solo: A Star Wars Adventure) the video displays correctly. AC3 is not always an option, because for some files the AC3 track contains audio description, which can be extremely annoying.

Hey plex team, any help on here?

Hi! Having the same problem! When selecting DTS audio image breaks! Server is running under Windows 10, i7 8700, RTX3080Ti. Client is LG CX App. Are you planning to fix this? Or your app is unable to play DTS movies? (what is the point of it then?)

same problem…

Client: LG OLED65CX9LA
5.22.1
Plex for LG
webOS 5.2.3

Server: Plex Media Server
DS1821+
Linux DSM 6.2.4.25556-0

I’m seeing exactly the same issue as OP on the same model TV. Direct Play video but transcoding audio dca to aac.

Can anyone from Plex team look into this LG issue?

Today, exactly the same bug has happened to me watching an mkv with

Format                                   : TrueHD
Format profile                           : TrueHD+Atmos / TrueHD

audio stream on my LG OLED. Has anyone else experienced this?
