Your log does show the Media Foundation codecs issue.

I have sent you a link to the pre-release version that has the fix. It is expected to be officially released in the next beta release

Works now. Thanks for the help. for the technically inclined, what happened?

The Transcoder had an updated ffmpeg and the codecs detection changed

Having the same issue here as well, would like to try the pre-release

Same issue here, could I get the pre-release? Thanks.

I too am having the issue on the latest update. I get “Conversion failed. The transcoder exited due to an error” when playing one specific show. I have re-downloaded it in various formats (1080P, various sizes in 720P) and it continues to error out. I have saved the debug logs but don’t want to post them here due to the revealing information contained in the logs.

Please advise on the next steps. I’m willing to hold off on downgrading my version of PMS to help troubleshoot the issue. Maybe if someone can send me the link to the updated Beta version, I can confirm whether or not this solves my issue.

EDIT: I’m on version 1.13.0.5003 on Windows Server 2016.

Same issue here. I’m on version 1.13.0.5003 on Windows Server 2016 Core

Same issue, should I move forward with the downgrade or do you guys think the new version will be released soon? On version 1.13.0.5003

Thx for everyones hard work though.

I didn’t see this thread when I first Googled. So I made another thread and posted my logs. I would also appreciate a link to the prerelease.

Same problem, can I also please have the link?

The fix is now official released as beta 1.13.0.5023

See release notice http://forums.plex.tv/discussion/comment/1665416/#Comment_1665416

  • (Transcoder) Media with EAC3 audio could fail to transcode in some cases on Windows. (#8547)

Anyone who had access to a pre-release development build must uninstall through add / remove programs before installing the official release (because of how version numbers are derived for windows)

Thanks - 1.13.0.5023 has fixed the issue for me :slight_smile: :slight_smile:

For me 1.13.0.5023 fixed it too, I want to thank SA2000 to report it as first and giving a workaround. Also nice work Plexteam to fix it so soon.

So, I ran in to this issue on a centos/RHEL 7

1.13.0.5023 did not fixed this for me

I deleted my libraries and re-added them and this did not fix it either
then I read something about 1.13.0.5023 using a later version of ffmpeg

Here is what I did to fix it.

  1. Install RPMFusion (https://rpmfusion.org/). yum localinstall rpmfusion-free-release-7.noarch.rpm -y
  2. Install latest version of ffmpeg that comes in RPMFusion repo. yum install ffmpeg -y
  3. Install other system critical updates, such as kernel updates. yum update -y
  4. Reboot
  5. Profit

I’ll be happy to provide logs to devs

hi all
i have just got plex setup up and working, wanting to turn my setup into the cinema like experience with movie trailers that are in my library, yer everything works fine until i enable trailers then i get the message “Conversion failed. The transcoder exited due to an error”. i have checked and all the setting that i have read are update and on the fasts/unlimited setting, i am on the latest server version “1.13.0.5023” seeing that some users are still having problems, i looked at @iamkaarp post and could not work it out im running it on a windows 10 pc that that is its sole job. i have attached my loogs for investigation. for now i can still use my plex as long as i disable trailers.

thankyou for your time

Hi @sa2000 - thanks for your continued work on making Plex better for everyone.

I am also recently getting the “Conversion failed. The transcoder failed to start up.” error. This error first occurred on May 14th and has persisted ever since.

I have been using Plex for years trouble free, it has consistently performed well for me, so to encounter this error is a new thing for our family. I have read through the forums here and tried other users’ suggestions, I have been reading reddit posts and tried some ideas presented there:

  • Uninstalled, reinstalled Plex.
  • Deleted libraries
  • Renamed files
  • Changed Transcoder directory
  • Set PlexTranscoder.exe to compatibility mode
  • Changed permissions of Transcoder folder

Still no luck, same result - same error: "Conversion failed. The transcoder failed to start up."

I am using the latest version of Plex 1.13.0.5023
I am using a Windows-10 64 bit, and windows is fully up to date.
I have had no hardware changes recently.

While it seems that all .mp4 files I have tested will play perfectly well, it seems all .mkv files I have tested will NOT play and will produce this error.

I have attached my log files here for your reference. Thank you for taking a look at this.

Serious issue with how you setup Plex Media Server
