If the above three solutions didn't fix the codec issue, then the next step would be to try asking for solutions on the Plex forums. To resolve this issue, you will need to go into /etc/fstab and manually remove the "noexec" parameter, or change it to "exec" to get the Plex to transcode again. If you have installed Plex on a drive mounted with "nonexec", this means that the Plex transoders will not execute, which will result in the transcoder exiting error. The drive that contains the Plex transcoder directory must be mounted with the "exec" option. If this resolves the issue, check for missing or bad subtitle files that are associated to the movie, or simply replace the subtitle files with new, good versions and try enabling subtitles again. Try disabling subtitles to see if the error disappears. Many times transcoder errors can be the result of trying to burn subtitles in the movies. Ensure the directory is accessible and writeable by the user running Plex. If Plex can't write to the directory, then this could cause this error. Plex writes out blocks of the media file as it transcodes so it can stream the file to the client machine, and these blocks are written to files in a temporary directory. Verify that the location of the temporary transcoder directory is in a directory that the user running the Plex server has write access.

Check the location and permissions of the transcoder temp directory While you are updating Plex, you should also check for updates to your operating system, just to be safe. Most releases of Plex tend to provide fixes to problems that users are having, so updating to the latest version could solve the issue. The first thing to try is to ensure your server is running the latest version of Plex Media Server. If you get this message when streaming a movie that is being transcoded, then there are a few things that you can try to resolve the issue. Most transcoding errors that are displayed don't provide much information as to the cause of the error, so it is up to the server owner to try and resolve the issue.Īn example of one such message is: Conversion failed. There are many errors that can appear when Plex Media Server attempts to transcode a media file.
