Universalmediaserver: external subtitles won't show if .mkv file has multiple subtitles embedded

[wesyr]

Hi,

Yesterday I've encounter a problem with mkv which contains multiple subtitle tracks and also an srt file.

The problem is that, Showtime can't load that requested srt file, when i type the link into a browser I get

Failure: 500 Internal Server Error

It has been also reported on showtime tracker:

https://showtimemediacenter.com/issues/1835

I've reproduced it on a second computer with UMS.

Link to forum topic:
http://www.universalmediaserver.com/forum/viewtopic.php?f=9&t=1516&p=9055#p9055

On forum I've attached logs from showtime and ums.

[wesyr]

I've create VM with Win7, installed only UMS with prerequisites (java and AviSynth).

Turned on Trace log on UMS and Debug all HTTP on Showtime.

Logs in attachment.

Interesting parts:

Another thing:

When i enter in browser

    http://192.168.1.46:5001/get/0$2$2/subtitle0000.srt

I get a blank page

After that when i enter into browser

    http://192.168.1.46:5001/get/0$2$2/jobs720.srt

Browser wants to download an srt file, i discard it.

Then i go back to

    http://192.168.1.46:5001/get/0$2$2/subtitle0000.srt

And now i see subtitles in plain text.

When the link on the forum cannot be access anymore that could mean that this issue can be closed ?

[Nadahar]

@Sami32 I can't access anything at the forum atm, so I'm not sure that's a valid proof that the issue is gone..

Edit: Now the forum link works for me.

[Sami32]

@Nadahar Thanks for your attention :-) Yes for me too now, but yesterday all the issues links was not accessible so i wrongly though they was deleted...my bad 8-/

I did reproduce this issue with the latest UMS version on an a Panasonic Viera renderer.
debug.log_EXTERNALSUBTITLES.txt
debug.log_EXTERNAL_SUBTITLES_scan.txt

It's working fine with MKV file and any external subtitle when one subtitle is embedded, but not when 3 subtitles are embedded, certainly with anything superior to one embedded subtitle.
So it's a UMS issue, as far as i saw in my log external subtitles are not recognized at the parsing time, so maybe it come from _DLNAMediaSubtitle.java_

It's look like externalFile value is not set correctly, or overrided.
Actually it didn't even detect the charset of the subtitle file.
N.B. It is the same external subtitle, i just renamed it.

@wesyr @SubJunk "(on Showtime)" could be deleted from the title of this issue, since it's not specific to a renderer, as well as ".srt" as it also affect the others kind of external subtitles. Thanks.

[wesyr]

Changed title to correct one :)

[Sami32]

@wesyr Thanks :+1:

[valib]

@wesyr is this issue still valid with the latest UMS version? Since 2014 I made a lot of changes. For me it works well.

[Sami32]

@wesyr Don't be surprise, it's the "subtitles" guy, so better to answer him if you need this issue solved ;-)

[wesyr]

@valib, @Sami32 sorry about this delay, i wasn't home for a week and didn't had chance to check this topic :) right now it's "night-night" time here where i am ;) , so i can check it tomorrow in the evening and of course will answer you is is still valid :)

[Sami32]

@wesyr Can you give us some feedback, please ?

[atamariya]

@SubJunk This should be closed as @valib confirmed that this works.
