Video will not play with subtitles

[Bobbybare 2]

I have a number of .ts files which have been recorded from UK Freesat and Freeview which contain DVB Subtitles .

Emby server will play the video files just fine but if the subtitle track is selected they will not even start to play.

These files are playable with the subtitles in VLC Player.

logs attached

Hope someone can help

To add to this thread;

I installed Emby server on my Windows 11 just as a test and in this version these files play perfectly with subtitles selected.

I guess it must be a bug in the Terramaster version of Emby Server v4.8.10.0

I installed Beta version 4.9.0.30 on the Terramaster NAS and tried again.

With subtitles selected after a short buffering period the video played with subtitles but the volume stuttered every time the subtitle changed. Very frustrating!!

The device is an F2-221 running v5.1.67-00214 with Video playing it's only using 1.52% CPU and 17.68% memory.

Hi, can you please attach the corresponding ffmpeg log file as well? Thanks.

I have played one of the offending .ts files for about a minute and attached the logs.

Thanks

Hi,

The video being played has a DVBSUB subtitle which is a bitmap-based format.  In order to transcode the video the transcoder has to burn in the overlay to make it part of the picture for each frame.  This is quite intensive to do and is being done on the cpu vs gpu.  Your server isn't fast enough to do this real time as it's speed=0.62x.

You may wish to turn on subtitle downloading for each library: This will pull down text-based subtitles that won't require burn in.

First configure Open Subtitle (Subtitle Menu)

Then configure each library to download the subtitles.

OK thanks

Now I understand the problem. with this NAS its .srt or .ass subtitle files, I will be interested to see what happens when I can afford to upgrade my NAS to something more powerful.

Thanks for the help.
