Plex Transcoder is crashing on file

General Discussions
1

Hello,

When I attempt to watch a file in Plex, the Transcoder crashes. Windows throws an error:

“PlexTranscoder.exe has stopped working”. Plex displays this error:

“Conversion failed. The transcoder crashed or failed to start up.”

The file works fine in VLC or MPC-HC. The MKVInfo on it is below. I’ve attached the most recent Plex Media Server.log file to this post; it is relatively short, in debug (not verbose) mode, and has a failed attempt to play the file.

Thank you in advance for the help.

Hi,

Thanks for your help. The files are only encoded with mkvmerge because I
don’t really have a choice. Plex doesn’t support ordered chapters in MKV
files and a large portion of my media makes extensive use of those. I
looked on these forums and found that the feature request threads for that
go back years (2013 was the earliest I saw), which suggest that it is not
coming any time soon, if ever.

Between the lack of ordered chapter support and potentially the inability
to play anything with flac audio, the prospect of needing to re-encode a
huge portion of my media to use Plex is really unfortunate.

I can attach the logs via that method when I am back at home. I did attach
the Plex Media Server log file to this post following a failed attempt; it
seemed to be the only log file with relevant info but perhaps I missed
something.

I will also grab mkvinfo for the original, non mkvmerge file. That file has
the exact same symtoms in Plex.
