Hi,

I need some help getting the subtitles to work in the Web client (to begin with).

I have used IE10, but also tried Firefox 33.1.1.

The Media file is a MKV with subtitles build in. I have attached the logs.

I transcode - Server version 3.0.5445.6 on Ubuntu

 

Log History

8:13:00 – Browsing the file via web client

8:13:32 – Media stream started

8:14:00 – Pressed play

8:15:30 – First sub should appear but does not.

8:16:00 – paused and play again (accident from the user ;) )

8:16:15 - picked subs (but mark is still in off when checking

8:16:40 picked CC

8:17:00 picked subs again

8:17:20 stopped media

 

Thanks in advance

Best Regards.

what makes you say First sub should appear but does not.?

 

​Also, can you post a sample video somewhere like dropbox? thanks.

 

Also, we extract text subtitles on the fly. this is done once per video and then cached. usually it's pretty quick and under 10 seconds, but on slower systems it can take longer when extracting from large video files. We actually kill the extraction process after 60 seconds in case it times out. in this case, it looks like after 60 seconds it was still only halfway through your video.

 

we may have to look at allowing the extractions to happen ahead of time via scheduled tasks. needless to say, external text-based subtitle files perform significantly better.

Thank you for spending time on this.

The person in the media file starts to speak, but there are no subtitle to it.

 

Sample here...

 

The hardware should be fast, but yes its a big file.

When using the sample subs Works ok :)

 

A conclution maybe?

Thanks in advance.

it is just a matter of it taking too long. we might have to look at switching subtitle delivery methods when the video is over a certain size, for instance, falling back to burning them in with transcoding. we just try to prefer text-based delivery whenever possible because it doesn't require transcoding and will help relieve cpu pressure.

Thanks, now I know how it Works.

It would be nice to get it fixed :)
