PGS subtitle doesn't appear

[Richard Branches 231]

I have this high bitrate h.264 movie with PGS subtitle, the movie plays directly but the subs doesn't appear:

 

 

However, on my phone they appear:

 

 

 

I sent the log at 1:15 pm on 26/03/18 and there is a server log attached.

Yeah, this is the same problem as this: 1.5.55 - PGS subs not displaying

 

I believe it is some variation of PGS formats from older discs but not sure.  It is a problem in Exoplayer and I haven't had a chance to put together everything that will be required to report it to them properly.

The file was remuxed from a recent star wars bluray.

​I discovered today the reason why PGS subtitles won't appear: starting with a software version I don't know, MKVToolNix is applying zlib compression to PGS subtitles by default, what I did was to remux the video without the compression and the subs appeared.

 

This is an issue I was having with Plex, however, it was with VobSub subtitles, I reported the issue and they already fixed it, I hope you guys do the same...

Thank for the info.

[ebr 14904]

Very interesting.  If that's the case then it is something we will have to take up with Google.

 

Thanks.

Today, april 19 2018, I received an update to the Android TV beta version 1.5.73g and PGS subtitles with zlib compression appear! ¡thank you Emby developers!

[Luke 37019]

Thanks for the feedback.

[Richard Branches 231]

What happened? I received an update to version 1.5.74g and now everything is getting transcoded

[ebr 14904]

Hi.  These are beta releases so things are constantly in flux.

 

Thanks.

[Richard Branches 231]

I know they are betas but that's not what I asked, what I wanted to know is why the videos with Dolby Digital 5.1 didn't get transcoded into AAC 5.1 in the previous beta version with "downmix to stereo" in settings and PGS subs inside the container but they are getting transcoded with this new update?

[Richard Branches 231]

I received the update to 1.5.75g and everything is apparently back to normal...

Good morning.

I have the same issue with the subtitles in my nvidia shield, I found the solution in the same way of you. Today i found your post.

 

My problem is that i have almost 2000 movies... imagine the work for re-remux all collection

 

I start remuxing the collection without any compression (video, sound, subs -pgs or srt) 3 months ago...

 

Somebody can help me with this or gove access to the beta channel? 

 

I already running the nVidia beta program around a year ago.

 

Thank you!

Don't remux your collection!, Emby developers are committed to solving this problem as soon as possible, just give them some time...

Hello Everyone, digging this back up because I am seeing this problem on a Sony Bravia (2015) TV and on my NVIDIA Shield TV. The PGS subs only show up when you force transcoding. Is this issue still being worked on, or do you need more information from me? I get the same results on the stable and beta releases of Emby. Is it better to use something like Open Subtitles and just download all the forced subs?

They were working fine when I had the Mi Box and they are working fine on my current device (Mecool KM8).

Hmmmm, thanks. I guess I may start a new thread on this.

[Richard Branches 231]

I don't think that's necessary, you can continue to troubleshoot this with Emby devs here, also maybe I can help.

First of all, let me know what audio codec or codecs does your video have? is the video in MKV container?

[otispresley 81]

OK, thanks! Here is the ffprobe information for the file I am working with. My entire library is the same...HEVC video, primary audio, and english subtitles.

The subs display when transcoding but do not when playing direct whether using stable or beta versions of the app. The client logs were uploaded at 7:00 PM Eastern. The server is running 4.0.0.2 on top of Debian Stretch. Here are the server logs if they help at all: https://file.io/xk9Ldj

Do you have your Shield connected to an AV receiver with only Dolby Digital decoding or to a TV with only Dolby Digital decoding?

[Richard Branches 231]

Is the audio also getting transcoded?.

[Richard Branches 231]

Alright you said the TV is Sony so maybe it doesn't have DTS decoding by HDMI when you connect the Shield to it and the audio is getting transcoded to Dolby Digital which also transcode the subtitles, can you please confirm this?
