HLS subtitles are not supported

[Okeur75 7]

Hello guys,

 

I searched on the forum but could not find anything regarding HLS subtitles causing error so here I am.

 

Problem 1:

 

I'm experiencing the famous "Playback error..." when watching some episodes.

I took a look at the logs and it crashed because "HLS Subtitles are not supported for this media."

The strange thing is that it happens only on 2 episodes (out of 8) even if the 8 seems to be encoded with the same settings and the same set of subtitles.

Some info that may help:

1. If I play the "faulty" episode without subtitles it works.
2. If I play the "faulty" episode with whatever subtitles it fails.
3. I can play the other episode with or without subtitles without any error.

 

Exhibit 1 the logs (full logs attached)

Exhibit 2 : The mediainfo from 2 episodes, the first one is working, the second one is not. Files attached.

 

Problem 2:(probably linked to Problem 1 but if not I can make a separate thread)

 

On the same faulty episode, when I play it without any subtitles, the progression time bar bugs, see screenshot below.(0:02/0:10)

 

 

 

Few seconds later the lenght of the episode appears to be 10:30

 

On the dashboard page, the transcoding information are not shown as usual:

 

 

 

Improvement idea:

Last but not least, it seems there is no error recovery for this kind of situation.

If we take the above example:

1. I'm playing the "faulty" episode without any subtitles and it works
2. I realise I need subtitles (because you know, french people don't speak english ). So I click on the CC icon and chose the first one -> It fails (blackscreen etc.)
3. Ok nevermind I will watch it without any subtitles, so I click on the CC icon and change it back to "Off". I would expect it to work but it doesn't. I have to go back on the episode screen, and start again the episode.

 

So to sum up:

1. What do I need to do to play the faulty episode ?
2. Is Problem 2 linked to Problem 1 ?
3. Can this error recovery be implemented easily ?

 

A lot of things in one thread, admins, do tell me if I need to split it.

Hello Luke,

 

I'm running Emby Server 4.1.1.0 and I see a similar error in my log file when playing a certain

episode:

The file plays fine with VLC. If you need additional information regarding this issue, please let me know.

 

 

Best regards
