Subtitles and Dolby Vision are not playing on LG WebOS TV

[Asazen 6]

I have 2 problems. I usually play BDMV but I've been trying for a few weeks with MKV files and to my surprise I've encountered 2 problems on LG WebOS TV.

- The first is that it doesn't play subtitles even though I have them checked (I'm referring to internal mkv subtitles in .srt format, plain text. I didn't test if the PGS plays them.) On the PC the subtitles work correctly.

- The second is that although my TV is Dolby Vision emby plays it in HDR, at the time of preproduction the TV shows a sign if it's Dolby Vision or HDR and always jumps to HDR.

DV on LG only works in MP4.

Can you make sure that you have all these user options enabled,

and that this setting is enabled in Transcoding settings on the server

From my experience "Allow changing of container formats" does not work to get Dolby Vision working on LG TVs.

[SamES 962]

No, you need to manually change the container for DV, but if you disable any of those options it might impact the subtitle extraction process

Regarding DV, you told me that LG only plays DV in MP4, is there no way for Emby to force it to play?

And regarding the subtitles, it is clear that it is an error in the APP because on PC, FireTV, Android TV, mobile the subtitles work fine.

No, not at present.  We would need to know whether the TV supports DV or not, and for that we are limited by the webOS api's and how well this is supported by LG.  There are also some other complications, but it might be possible in the future.

It's possible, but those devices might be able to support playback without subtitle extraction, but for the LG it might be required.  If you have those settings disabled, then enabling them to confirm if that is the issue is the first step.

Aside from that, we would need more information to understand this issue more fully.

I had all those options activated by default so that is not the problem.

A new version has just been released and I still can't play subtitles, unbelievable...

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

In the server settings, in the Transcoding section, do you have this enabled?

Yes, it is enabled, and the server was reinstalled from scratch just 1 week ago so there is no error in it. Tomorrow I will upload the logs after playing them in the LG app.
