The film ticks in sounds and image when I use under subtitles on all films.
Without subtitles, they run as they should.

Why ?


It's something that's starting to come.

I have a Synolygy 920+ with DMS 7.0

Hi, Does this happen on only a specific movie or does it happen to all films?

Does it only happen with one specific sub type?

It happens mostly when I have to send it to a Chromecast not all movies but eventually a lot of them.

The film is in mkv with built-in subtitles. and mp4 with built-in subtitles.

But what type of sub are they?

Can you show the media info section of this media files that was casted?
Bottom of the media file's detail screen.

Also please attach the emby server and ffmpeg log files from when you tried to play. Thanks.

When using the PGSSUB your NAS configuration is not able to process this in hardware and reverts to software transcoding.

Then trying to transcode via software it's not fast enough to keep up.

What you should try and do is download an SRT subtitle that can be used for this media while still allowing hardware transcoding.

Yes Maybe I can see that plex does not have the same problems as emby with playing. So a shift is needed.

OK try this.  Go to transcoding menu and set the top option to Advanced.  Now you will get a list of all Decoders and Encoders.  Try unselecting VAAPI and use only the QuickSync options so it will look like this.

same for other decoders

Click SAVE at the bottom of the page and try again.

Let us know if this works better for you.
