Subtitles and .MKV files

I have recently noticed that all of my, .mkv movies with subtitles gives an error when playing on the Apple TV.

Plex web, plays them ok and when I convert them to .mp4 they play fine on the Apple TV.

Is there a magic fix for this or do I need to convert them all?

Thanks for your help.

With which versions of the player and server apps are you experiencing this?

If you use the transcoder forum preview, be on the very latest version.

I am currently running Plex 1.43.0.10162 and Plex for Apple TV 8.45 (9684)

Some seem ok but I have noticed the ones with the .srt file added separately are causing the error

Looks like a bug in Plex

@claynz From looking at your screenshot, SRT details,

  • the language is unset.
  • it’s forced,
  • yet it’s labeled as original language
  • and also labeled as commentary.
  • we can’t see whether it’s a UTF8.

Would you examine one film that works against the one that doesn’t, then compare and contrast the track settings?

This could be an instance where a sample file of your IP Man 3 would help,
but I understand if you’re reticent. Maybe you’ll post the mediainfo output for it, though.

Still trying to replicate your bug. I have success with MKV + SRT on AppleTV.

Try extracting to an SRT file with ffmpeg:
ffmpeg -hide_banner -i “yourfile.mkv” -map s:0 “yourfile.en.srt”

(If the captions are in -map s:0, if not, try -map s:1)

Thanks guys for the follow up, I only had a few MKV with subs so just converted them to MP4 and they play ok, having found out later there is an issue with Plex playing standard MKV files so in the meantime I have turned off Auto Adjust Quality in the Plex settings for Apple TV
