Player Version#: 4.40.1

Hi,

I am using plex media server on true NAS beta-2. I am getting Conversion failed The transcoder exited due to an error when I am trying to play any video with subtitles from opensubtitles. Can anyone please tell me why this is happening? Some videos do play fine. I can see the file in transcode/session/ when the video with subtitles plays fine.

Same here, almost all SRT subtitles result in a transcoder crash when starting a episode.

Episode only works when turning the subs off.
Its getting a little annoying cause the last 4 weeks it starts happening more often then not. And im not sure what is causing the problem.

I have the same setup handy. I usually go out of my way to Direct Play so no transcoding is involved, and I haven’t noticed this. But I can try.

Are these subtitles that were downloaded by Plex automatically (or that you selected and downloaded in the UI)?

Are you using the TrueNAS Plex Plugin?

yes, subtitles were downloaded automatically with opensubtitles. And I am using TrueNAS Plex Plugin with version 1.19.5.3112. Previously the error was different because it did not have any permissions to create a temp file in transoder directory but now sometime when it plays there is a file under that temp directory.

I am also seeing this after moving to a docker image.

I’m stuck on version 1.16.6.1592, because every other version I tried upgrading to causes this error.

I’ve been following other posts about this, but they all closed after a while because there were no replies after 3 months.

Is this ever going to be fixed? I used to be a plex pass member, but I canceled it after updating & needing to rollback my plex server.
I’m also not planning on becoming a plex pass member until this is solved for obvious reasons.

Edit: here are the other issues I was following:
