No subtitles on any Movie or Episode

[JimmyS01 0]

Hi,

When watching on my Apple TV 4K

it will not show any subtitles on movies or Episodes.

The server is running the latest version on Windows 10.

I have tried restarting the server, the Apple TV and also tried reinstalling Emby on it.

From the server log it looks like it fails on extracting the subtitles from the file.

I use embedded srt files in a mkv container

It is working on both my android phone and all the smart TV's

i have access too

 

from the serverlog it reads:

@JimmyS01 Hi there, can you please attach the complete emby server log? Thanks !

Yea, sure thing

Here you go

We extract the subtitles on the fly, but it looks like for your server this process takes too long. In server transcoding settings you can disable on the fly subtitle transcoding.

Please note, this will result in a lot more transcoding, so you might not like that either. Try to use external subtitles for best performance.

Ok, so if i keep them external it should work better

One thing, if i upgraded the server wouldn't the extraction potentially be faster too?

Only question for that would be, as i am using my GPU for transcoding, if ffmpeg uses the GPU or the CPU for extracting the subtitles?
My own though would be CPU?

Yes,, but the extraction has to step through the whole video file, and in many cases it is disk I/O performance that becomes the limiting factor, not cpu/gpu.
