Cannot play media with subtitles

[drengelsk 0]

Hello

 

I finally got my Emby Server up running on Windows Server 2012, but I have a problem with streaming movies and series with subtitles. I stream my content via Chromecast (3rd genereation), but movies and series will only play, if I turn the subtitles off, otherwise I will just get a black TV screen. The subtitles are already incorporated in the MKV files, and also the media are not transcoded, when the subtitles are off.

 

Best Regards

What kind of subtitles are in your mkv files?  But you will most likely need to post a server log and ffmpeg log if present when trying to play a item with subtitles.

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. thanks !

The subtitles codec is called SUBRIP, otherwise I don't which format it is... The log file is attached.

Is the syntax correct?

Yes, curious. What kind of drive is your F: drive?

Inside a filter string, there are special escaping requirements. 

I don't know these rules  from the top of my head, but I still spotted something.

 

Could you post the complete ffmpeg log?

That was from the log in post 4.

Thanks happy!

 

I would think that the :si=0  part needs to be outside of the single-quoted filename.

 

But I just looked at the code and it hasn't changed for 1.5 years..

 

@@Luke - any ideas ?

Edited October 15, 2019 by softworkz

[Luke 39638]

I think the code is OK. I'd like to know what the F: drive is.

[Happy2Play 9352]

I don't see how subtitles='F\:/ and fontsdir='C\:/ can be correct.

Read the ffmpeg docs..

I guess I don't know were to look as that Window path looks wrong but looking a other OS logs it would appear correct.

should it not be something like this with backslashes?

Do I really need to say it a third time? And provide evidence?

https://superuser.com/questions/1247197/ffmpeg-absolute-path-error

 

Open a command line on Windows and type the following:

c:/windows/win.ini

It is not commonly known but Windows accepts forward slashes as well as path separator .

Using forward slashes instead of backslashes avoids the excessive escaping that would be required otherwise.

 

That's the one side.

 

 

The other side is, that a colon ( : ) is a special character inside an ffmpeg filter spec string.

 

That's why it needs to be escaped with a backslash.

Emby is installer on the C drive and the F drive is just an external drive.

Thanks, there is not way I got any of that out of that documentation.

Could you please try to run this command manually from the command line?

Are there certain conditions for the existence of the /programdata/fonts folder?  None of my systems have this fonts folder.

Sorry, you're right. 

You could quote it, or you can also just navigate to that directory and then execute starting from 'ffmpeg...'

Softworkz, do you want me to run the commands in CMD or somewhere in Emby?

[softworkz 4491]

in cmd

It didn't seem to work quite well...
