Problem with transcoding and subtitles


Recommended Posts

Posted

Hi,

 

Been testing Emby Server on a Synology NAS and on a Nvidia Shield Pro.

 

Both show the same problem: when I view x265/HVEC content in Chrome webbrowser, or in the Emby iOS app, they will stutter when subtitles are enabled. But, not not with all subtitles, it seems (at least the webbrowser player) sometimes does work.

 

I don't know what more to test, but is this a known thing, or is there anything I can test specifically to better understand what is going on?

 

Thanks.

Hi, probably because they have to be burned in with transcoding and this might not be happening fast enough to be playable. If you can attach the emby server and ffmpeg logs then we can confirm that or if it's something else. Thanks.

I hope these are OK... During playback of the x265 content, I see in the 'stats for nerds' info that it is transcoding because subtitle format is not supported. When I disable the subs on that content it transcodes very quick.

So thats your answer.  Get rid of the burned in subs and download the externals.

Hi yes your transcoding with the subtitles included is just not happening fast enough. The easiest resolution would be to acquire external text subtitles and use those instead. We have a subtitle download feature built into the server that can help with that. Thanks.

It seems the problem is VOBSUB type subs, and indeed selecting SRT subs works fine.

 

FYI: Plex also has problems with this ;)

 

Guessing there is no option in Emby somewhere to ignore VOBSUBs by default?

Hi, there is no option but you could use our subtitle naming guidelines to mark your external subtitles as default.
