Transcoder Error caused by Samsung TV

Plex Players Smart TVs

Server Version#: 1.32.5.7516
Player Version#: 5.69.1

I get the error “Conversion failed. The transcoder exited due to an error.” when approaching the end of a stream while watching content from my PMS running on Ubuntu 22.04.3 on a Samsung TV (it does not happen on other players). I looked at the logs (shown below) and I noticed a negative byte offset that caused a segmentation fault.

Are subtitles enabled?

If so, that’s a known problem and fixed in the current beta release.

I just tested without subtitles enabled and everything works as expected. Any idea of when this update will be available for non Plex Pass users? Until then, is there a version I can downgrade to where this problem does not exist? Thank you!

Here is the main thread on the topic: Conversion failed playback error when subtitles are over (usually at the end)

OP was running 1.32.2.7100 at the time, so you would have to fall back to something earlier than that.

When fix will be in pubic version is unknown, but possibly within the next week, based on last post in thread:

Ok, thank you!
