Update broke Emby

[JJKOM 1]

I have been using Emby over a year now on my Terramaster NAS with TOS (5.1.67-00214)
I had 4.8.0.62 beta and everything was working fine on my Samsung 55" OLED. 

First problem came with Samsung 75" QLED - no subtitles displayed, while same file displayed subtitles on 55" OLED
Then I tried on LG 43" - it wanted to update Emby client - no subtitles. 

Then I made a mistake and updated Emby Server on my NAS. 

First with 4.9.1 from website:

Playback Error

No compatible streams are currently available. Please try again later or contact your system administrator for details.

This comes with all my TVs AND on browser, even on Terramasters own Home-page.

Then I tried beta 4.9.2

Same thing. Now I can't play any files. Not even on Samsung phone. Same files have been working just fine before.

So there is NO change on files or hardware, only change is Emby server on TOS5 

Is there old version to be re-installed?

Hi, looks like authentication is failing for each of your network shares. You need to go into Emby library setup, click on each library, them click on each folder in the library and configure the credentials for it.

[JJKOM 1]

ok - so just installing on top of old is not good, I'll try that

I changed permissions on folder that has just movies in it and tried. Same error.

Hi, what exactly did you change?

[JJKOM 1]

From Emby mainscreen - Library - folder "Action" 
There was nothing on user or password, and it did not accept anything else than TOS main username and password.

[Luke 42077]

Is the media on the nas or another device on the network?

[JJKOM 1]

it is on NAS - no change on hardware and it has been working 

 

[Luke 42077]

Then why did you setup your libraries with network paths rather than the direct file paths?

 Besides this issue you will get much better performance using the direct file paths.

[JJKOM 1]

When I was first setting it there was no other option.

So I should change all those now?

But is that something that has changed on this new version?

[JJKOM 1]

Thanks, seems that changing those paths is giving access back so videos are playing.
But still no subtitles on my LG TV 
I will finish tomorrow  setting all new paths and permissions and then test with other devices.

[Luke 42077]

the ability to use the path has always been there. Actually we had that before smb.
I don’t know why you’re getting authentication errors. I understand that you’re associating it with the update but I think it’s a matter of making sure the credentials are configured on each folder.

Sounds good. Can we look at an example of the subtitles? Has the initial library scan finished?

[JJKOM 1]

Now I can play videos again.
Testing subtitles which was original problem;

Subtitles are SRT embedded to mkv. 
Testing on same movie:

Samsung S22+  - subtitles play ok

Samsung Smart TV (TQ55S94CATXXC) Emby for Samsung 2.2.5 - subtitles play ok

Samsung Smart TV (QE75Q70AATXXC) Emby for Samsung 2.1.0 - no subtitles

LG Smart TV (43UM7100PLB) Emby for LG 1.0.47   - no subtitles

All TVs have latest Emby available through their own store.

I have never been able to use any other subtitles than SRT so I only use SRT that is embedded in mkv.

There is no debug option on LG Emby app - or at least I could not find it.

Here is server log, just tried to play and no subtitles.
Same log has previous sessions where I tried all TV:s and phone.

@JJKOMthere are three problems that you need to correct that I think will help resolve your issue.

First:

	System.UnauthorizedAccessException: System.UnauthorizedAccessException: Access to the path '/Volume2/Store/Karaoke/SunFly/SFVCD 024' is denied.

Looks like there's a permissions problem where the server is being denied access to your folders.

Second, authentication is failing for your network share:

You need to click on the library in Emby library setup, then click on the folder, and then configure the username and password for the network share.

Is that share on another device on the network? Because if it's the same machine as the server then you can save yourself a lot of trouble by setting up the library with the local file path instead. It will also perform better.

That one is denied as that folder has VCD images. 
I removed that whole share as it is not really used with Emby.

This one is old, I changed all the paths. Movies do open and play now. 

[JJKOM 1]

I don't find that setting you refer to, there is these two "Playback" items in settings:

This is found in emby admin UI under users.

[JJKOM 1]

After changing those Media Playback all on - no change.

Still no subtitles on LG Emby.
Testing on Samsung 75" with Emby 2.1.0 today.

And I only use SRT subtitles that are embedded in MKV as that is only format that they work.

I have several files with different subtitles, some of them show on Emby as options on subtitles but selecting them produces nothing.
