Hello!

 

I'm trying to watch some movie on an old smart TV which already has browser integrated. (Unfortunately no native Emby is on that)

All the movies are playing nice and smooth, very good!

 

However if I play a movie with subtitles, the browser asks for webvtt. Emby then converts my subtitle on-the-fly to vtt and pass it back to the browser.

Texts are displayed under the movie, but they are delayed by more seconds, so it is not usable.

 

I have compared the vtt file and the original srt, and they are identical (by time-perspective).

 

 

Here are some of the log:

Do you think there is something that I can try?

(On-the-fly subtitle extraction was enabled, if I disable it is still not working - there was no subtitle then)

 

Thank you!

Hi @danergo, have you checked the subtitle timings? Are they actually in sync with the video?

[danergo]

Subtitle timings are okay. At least I believe so (on every other device and platform it works well).

This particular device has low memory which might cause these symptoms and I wanted to know if there is something I can still try.

 

So to answer: if I change the subtitle timings it would ruin the subs on the other platforms and on other devices.

 

What do you think?

@danergo

Yes this probably would be a problem. In the future we plan to add subtitle delay settings, but we haven't gotten there just yet. I suppose you could consider two sets of subtitles, although that would be a pain in the neck.

[pwhodges]

Another workaround would be to re-encode with hard subs, using Handbrake, for instance.

This made me ridiculously happy, it's something I've been missing since like, forever. Can't wait for that to happen 

[danergo]

Yepp, reencoding is one option but in this case I guess transcoding could also work, right? It would unload the stress from the TV and balance it towards the server which is much more powerful.

[Luke]

Possibly. You could try that. Let us know how you get on. Thanks.

You could you 'subtitle edit' and create a new subtitle file with suitable delay/advance and then just play that when on this particular device.
