Plexserver cant decode DTS issues

Plex Media Server
1

Server Version#: 1.21.0.3616
Player Version#: Plex Web 4.43.4, Plex Windows App 1.19.0.1399-31d8c803, Latest Plex Samsung App, Latest Plex App for the FireTV

Since 2 days I have had a problem with files that have a dts audio track.

Nov 29, 2020 11:11:13.884 [0x7f901a7fc700] ERROR - [Transcoder] [dca @ 0xf33600] Not a valid DCA frame
Nov 29, 2020 11:11:13.884 [0x7f90197fa700] ERROR - [Transcoder] Error while decoding stream #0:1: Invalid data found when processing input

I currently run Plex in a Docker Container (https://hub.docker.com/r/linuxserver/plex)

What I’ve already tried:

  • refresh meta data
  • moved back to older versions from plex server
  • repull docker container
  • update & restart host

What else I noticed: All the films that cause problems are actually HEVC, but are displayed in plex Mediainfo as h264.

That may be because I had two versions (h264 & hevc), i delete the h264 version and rename the hevc version to the old h264 version name. but I actually thought that a refresh meta data is enough to recognize it again correctly

Now the question is, what is the easiest way to fix the problem

Easiest way to confirm what’s happening:

  1. Get the XML of the file as currently seen (save this info)
  2. Hit Analyse for one of them (the test candidate)
  3. Get the XML after analysis (save)
  4. Get ffmpeg -i or mediainfo analysis of the file.

Present here if different so we can look at it.

A sample of the file (a dd of 10-15 MB or so, in a zip, would be sufficient)

Analyse solved the Problem. I tried it first with a single movie, there the media info changed from h264 to hevc. then i had the whole database analyzed again, now the movies can be played back normally.

thank you :slight_smile:
