.srt subtitles won't show if .mkv file has multiple subtitle

[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

Code: Select all

Failure: 500 Internal Server Error

As an attachment i'm providing log from ums and showtime.

It has been also reported on showtime tracker:

https://showtimemediacenter.com/issues/1835

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

Anyone knows what can be the problem ?

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:

UPDATE
Uploaded correct debug (trace)

Another thing:

When i enter in browser

Code: Select all

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

I get a blank page

After that when i enter into browser

Code: Select all

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

Code: Select all

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

And now i see subtitles in plain text.

I can see that, more and more people are having this issue with external subtitles, not only here but also on pms forums and showtime forum - also have logged that issue in both places but only devs form showtime were able to respond.

And the only answer I'm seeing here is "use Transcode folder", it's not a fix but a workaround, and i do not have that folder and don't want to transcode because my ps3/tv can stream it and i don't want to put load on my PC.

So anyone ? Somebody ? Devs ? What do you need to help pinpoint what's the problem? I can deliver more logs if you need, more tries more combination, because i don't want to remux all the time my mkv to cut internal subtitles.

[Wolfgan]

Interesting, I was puzzled why some mkv didn't show external subs when the srt existed on the same folder (and my renderer supported it).
Will try to test on my end as well. Thx! Wolf

Hi wesyr, firstly I appreciate the effort you've gone to in giving us info about this issue. Thanks
Is there a previous version of UMS that this worked on? It would be great if you can try some previous versions and find the last one that worked, if any.

[wesyr]

Hi SubJunk, great to hear from you

So i checked UMS till 1.5.0 version and it doesn't work

Everytime before installing UMS I've deleted main folder from Program Files and also from ProgramData, after install I've made two changes:

1) Copied renders folder - PS3/Showtime configs
2) Added mkv,avi to be skipped in transcoding

Even tried 3.4.1 - built today, but it's a no go.

One thing that I've observed is that above version 1.5.0 it was sending empty link, and the HTTP respond was OK 200, on version 1.5.0 it gave 500 Internal Server Error (maybe difference in Java version when 1.5.0 was built and new versions).

So that's for now. If you need something - newer trace log from UMS and Showtime, run the same mkv with and without interal subs or some other combination, just write it here

@SubJunk
This bug was always present. It depends on renderer if empty page or subs are returned.
Also me found this behavior with internet browser...

Hi again,

been trying to combine various options like here:

Post in: Subtitle problem

But also no change.

Maybe there is some other way ? Like disabling only INTERNAL subs in mkv file from GUI/config ?
