Plex Media Server Logs_2021-08-11_11-53-31.zip (90.3 KB)
I’m trying to play some anime files from my Windows 10-based server to my 2020 Samsung Q80T.
Specific examples in the log are S01E17 of ‘To Your Eternity’ and S02E06 of ‘Miss Kobayashi’s Dragon Maid’
I didn’t have any issues playing similar files until about a month ago or so. It looks to be something related to the subtitles (embedded .ass subs in MKV) as if I disable the subtitles before starting the episodes, they play fine. It’s only when the subtitles are enabled that the error occurs.
They seem to play fine via Firefox on my laptop, but doesn’t work via Plex on my PS5.
Let me know if there are any other logs I could provide or other actions I can take to be logged if needed.
