ASS subtitle formatting issues (iOS, Apple TV, Android, Kodi)

[iBoss 31]

Hi,

 

There is some issue with ASS Arabic subtitle (actually I don't know if it's there in English as well).

 

Please see the screenshots.

 

 

Server: Ubuntu Linux 16.04.5

Emby Version 3.5.2.0

The log file and subtitle is attached

 

Thanks

What exactly is the issue?

[iBoss 31]

Hi Luke,

 

The word with color style not at the correct position in iOS, Android and Apple TV emby app (attached ios.png); it should be as (attached chrome.png).

 

Kodi shows the ASS but without any formatting/color (attached kodi.jpg)

 

with chrome, it works perfectly.

 

I hope now is clear

 

Thanks

Which android app, the TV app, or mobile app?

[iBoss 31]

Android TV app

 

actually I dont have android mobile app to check

[Luke 42077]

I can reproduce this with all of our apps that use the mpv video player @.

 

I think this issue needs to be reported to mpv.

They won't pay attention to it without logs and/or examples to work with.

 

You'll want to report as much info as you can. I would do it, but I don't have anything to work with. And if it's the android app, don't get your hopes up.

Thanks for the advice @.

but I have already attached the log

 

I mean the mpv log. When I get around to testing, I'll generate a log and make a report. As for Kodi and Apple, I can't do anything with that.

[iBoss 31]

- Can I generate mpv log from emby android app? or should I download mpv app and generate the log from it?

- In Goolge Chrome (Mac), it works, what is the player use for emby browser?

Is it because Apple use own video player so you can't do anything ?

 

Ok what about transcoding the video and make hard subtitle on it, is it possible? (if it is possible, please tell me how)

MPV is the player in the windows desktop app, I'll test with the MPV, directly.

 

You can burn them in, if you want to.

I know about MPV Player .. I have tested the subtitle there and yes it has the same problem.

 

I have some question:

 

1- Is emby android mobile and tv app use this mpv player as android default player?

2- Why does the subtitle work in emby browser (Chrome)?

3- So the issue from the player not emby?

4- How can I force emby server to burn subtitle before send the video to the emby client app?

 

Thanks

The Android mobile uses mpv. Android TV has the option to use mpv, but isn't the default.

 

If you want to have the server burn them in, just lower the bitrate on the palyer to below the file bitrate. That will make it transcode. Now here's where I'm unclear. Your subs are external, I'm not sure they will get burned in or not.

 

The player in chrome seems to be able to handle them.

 

The issue would appear to be player related.

 

Until I test it and see what's happening, I'm just speculating. MPV has a multitude of options

[Guest asrequested]

If you really want to be proactive, you can enable logging for mpv, and submit an issue report to mpv.

Or if you don't have a windows machine, grab the standalone from their website.

Can you share the actual video, that you're playing (with the subs)? I'm playing around with your sub file, but I want to verify something.

[Guest asrequested]

For mpv, this may be needed. But as I can't tell if it's correct, you may have to test it yourself.

You might be right, although it doesn't seem like any of the -sub-ass option default values will cause any problem.

 

This is interesting though:

--sub-ass-shaper=<simple|complex>
Set the text layout engine used by libass.

simple:	uses Fribidi only, fast, doesn't render some languages correctly
complex:	uses HarfBuzz, slower, wider language support
complex is the default. If libass hasn't been compiled against HarfBuzz, libass silently reverts to simple.

I don't know if libass is compiled against harfbuzz or not.

[Guest asrequested]

With the override on, I had the subs overlapping. Turning it off, the positions looked correct. But I can't read it.

[Luke 42077]

You mean you tested with this exact same subtitle?

[Guest asrequested]

The subtitle he posted in post #1

[iBoss 31]

@ @@Luke appreciate your support.

 

I can provide you the video ... but after some investigation, it seems the subtitle itself wrote on the wrong way    .. I'm not sure but I'll try other ASS subtitle later

 

In the meantime please leave it until I make sure about it .. Sorry about that.

 

Many thanks to you

Anyway I have tried this but nothing changed
