Roku subtitles

[nfg177 0]

When i watch on my pc through emby theater the subtitles show up and work perfectly. When trying to watch on my roku TV the subtites show in the dropdown menu however they do not show up when playing the media. Noticed only with MKV files. Any ideas ?

To enable anyone to say anything useful, it would help to know what kind of subtitles they are (see the bottom of the details screen for the item), and what the various settings in the server and the Roku relating to subs are set to.  Most of this information is saved in the server log from the time you had the issue, so the starting point is to provide that as detailed in this advice:

Hi, yes let's please look at an example. Thanks!

My apologies I sent a log from the roku device. The subtitles are internal in .ass format.

Have you set the Roku configuration to request burning-in of SSA/ASS subtitles?

Yes, please select this option in the app playback settings.

Hi there, new Premiere user and I'm seeing something similar:

Server v4.7.1.0 on Ubuntu 20.04

Roku OS 11.0.0 build 4193-29

Emby Roku App 4.0.55

Roku and server on same local network.  Source media is MKV with x265 video, DTS-HD audio, embedded PGS subs.  It direct plays when subs are off.

If playback is started and subs are turned off, turning them on during playback does not trigger a transcode (and thus no subs).  After stopping playback, the subs remain enabled, and when re-starting playback the transcode will happen and subs are displayed properly.

If playback is started and subs are turned on, turning them off during playback works properly - the stream switches to direct play.  They cannot be re-enabled without stopping and restarting playback as above.

Same behavior regardless of "Burn in SSA" option in the client.  The user's subtitle language is set to English and the mode is Default.

Embedded ASS and external SRT can be turned on/off without issue during playback (transcoding not required).  So it seems like it's an issue of the transcode not being forcibly triggered when enabling embedded PGS during playback.  It's a minor issue but the wife did notice it pretty quickly as she prefers subs on (we just set her sub mode to Always Play).

Checking the embyserver.txt log file, there is no event logged on the server when the PGS subs are enabled during playback, unlike when enabling external SRT:

@speechles can you see if you can reproduce this?

I think I'm having this issue but can't find this setting/how to request burning in.  Where is it?

Thanks

 

Edit: I think I found it, under transcoding I unchecked Allow subtitle extraction on the fly and now ASS subs are showing using Roku.

Hi, did you read the help text underneath that option?

Yes but not sure if it is the same as mentioned above about "Roku configuration to request burning-in of SSA/ASS subtitles".  Maybe the wording has changed.

I know I never had trouble with subs before either in an mkv/mp4 file or external SRT, but I noticed it when Shantaram came out.  It was working fine, then on E06 I noticed it wasn't so had to start getting the SRT file for subs.  Then I checked another show and it didn't work either.  So I don't know what changed if it had to do with a Roku update or Emby update or what happened.

Hi.  No that is not the option pwhodges was referring to.  The option he was talking about is in the playback settings in the Roku app itself.

Ah now I see it.  If I enable that, it won't actually change my media permanently on my storage will it?

No, it will not.

Great thanks, been working.  Although instead of the show starting right away it now takes maybe 15-20 secs showing the loading circle with % in the middle, guessing it is transcoding the show to add the subs.
