It looks like a new Beta fixing this issue is released: (Transcoder) Unexpected behavior when subtitles ended before the end of video (#14426) Plex Media Server - #596 by drzoidberg33

Note: There is another bug with subtitles on the LG Plex app: LG C9 TV: Conversion failed. The transcoder exited due to an error happening occasionally - #68 by cremor So if you test this one here by skipping/seeking to the end, then maybe you instead trigger the seeking bug.

Same here: MKV with internal SRT playing on LG WebOS 6. At the end of the SRT file, the transcoder (that should not be active, it’s direct play for both audio and video, as shown in Dashboard) crashes. I have crafted an external SRT file that has the last entry AFTER the actual end time of the vide…

Hmm reposting here as i think (not sure) i have the same issue. LG OLED G3 (latest model). I also see this error in kernel / syslog output. Anyone else getting that? I provided debug logs in another thread Plex Transcoder segfault libavformat.so.59 - #3 by JaysPlex7 [463692.815417] Plex Transco…

I’m experiencing the same on my LG G1 and created a separate thread: Playback issue near end of content I’ll watch this thread, I hope we get a bug fix soon, at least for Samsung and LG players. As you can see in my thread, there is also a ton of complaints on Reddit regarding this issue.
