Stuttering when subtitles are on with Apple TV 4K

Server Version: 1.18.5.2309
Player Version: 2.13 (14243)

The stuttering happens with all types of files and codecs.

Let me know if I need to provide more information.

Some subtitles will force transcoding of the video so:

  1. What OS and hardware is your PMS installed on?
  2. What type of subtitles are you using?

More information here:

and here, under Subtitles

PMS runs in a docker on Unraid.

SRT Subtitles, and the playback is direct play.

This is happening to me as well. Problem goes away when turning subtitles off. Looks as if the video drops a frame every so often. Once you see it you can’t unsee it. Very annoying. Also seems to be happening in Infuse.

I can confirm that this happens with Infuse for me too.

I also tried all the subtitle burning options. And on the Apple TV settings, I’ve tried turning off match content framerate.

Nothing has any effect on the issue.

Anyone ?

The issue persists on latest public PMS and latest version of the iOS app.

However, latest version of infuse plays files without stuttering.

Can someone provide any help ?

I can also confirm. Playback looks like a frame of video is dropped at random points. Just upgraded to PMS 1.19.3.2764 on a Synology NAS 1019+ direct played to 4th Gen ATV, whatever the latest player is.
