Conversion failed. The transcoder crashed or failed to start

Since last update in constantly get the error above. I have tried everything on the forum including completely uninstalling and reinstalling but still get this error constantly. Here are my last set of error logs. I really need some help, please. Kurt

Does the problem only arise when playing back on the Roku Premiere ?

I believe this file that was being streamed at the time F:\F - TV Shows\Channel Zero 1x4.mkv
Could you see if the same failure arises with a short clip created from this file - eg 5 minute clip (you can use mkvtoolnix) and create a small file that you can add to a test library to replicate the issue

If you get it to fail with the clip please provide that as well as the server logs

Would like some extra transcoder diagnostics for this error and if a possible a 5-minute clip file that you can get the failure on

Using RegEdit
Locate HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server
Click on Plex Media Server in left side area
Right click and select New \ String Value
Name the new string item TranscoderLogLevel and give it a value of verbose
Click OK and exit it RegEdit

Restart the Plex Media Server to get fresh logs created

And let me have the zipped logs on getting the failure

And the clip file that the issue was reproduced with
Please upload to dropbox or google drive etc and share link

When I first came home I watched Youtube directly from Roku for awhile with no problems. Then went into Plex/TV Shows and started watching Channel Zero 2x2.mkv and the transcoder crashed just a few minutes later. Then closed Plex and re-started it, created the log and enabled verbose logging, then went right back to the same TV show and the transcoder crashed again in just a few minutes. Then closed Plex and re-startrd it again and created second log. Here is the first log --> https://drive.google.com/open?id=0B1VJiFgO9DclQ1NfQ1ZVWGhfMWc Here is the second log -->https://drive.google.com/open?id=0B1VJiFgO9DclMGZEMU5EVkNtREk I really appreciate your help with this, I have no idea what to do.

I can see Verbose logging from Plex Media Server in the logs but I cannot see the new transcoder logging as a result of adding TranscoderLogLevel to the registry -

Could you get me an export to text file (save as text) of the registry area
HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server
and send it to me by Private Message

Thanks for sending me the registry export of the settings
It was done incorrectly.
Three errors

  Name:            Transcoderinglevel
  Type:            REG_SZ
  Data:            0

First error is the name of the registry key - it was supposed to be TranscoderLogLevel and not Transcoderinglevel
Second error is it was supposed of type "String Value" and not "REG_SZ"
Third error is it was supposed to have a value of verbose and not 0

So please delete the key and have another go at following my request outlined here https://forums.plex.tv/discussion/comment/1542929/#Comment_1542929

18 months down the track, we have recently discovered that these specific transcoder errors are currently due to Malwarebytes Premium blocking some localhost Plex Transcoder requests.

I do not know if you were using Malwarebytes on Windows - and if not, it could have been some other similar security software
