Remote playing subtitles issue

[mark235 5]

When I remote play movies on my mobile devices, only external subtitles (.srt files) will load. Selecting embedded subtitles while playing a movie causes playback to stall permanently, but the app does not crash. If embedded subtitles are pre-selected from the movie details screen, the movie will not start playing, but show the spinning circle.  

 

The issue can be reproduced consistently, and also occurs when remote playing through other Emby clients, such as a laptop with Emby Theater, tethered to a phone hotspot (4G network).

 

The issue is not present when direct playing movies, embedded subtitles then load properly on all devices. 

 

I have enabled the "Allow subtitle extraction on the fly" option, but then playback also stalls. The difference is that the mobile app does crash within a minute or so, instead of hanging indefinitely. I sent an error log through the Android app at 21:42 local time. Movie file was: 27 dresses. User: Mark. I've also attached the server logs below. 

 

Emby server and client settings are set so that when remote playing, movies will (almost) always transcode, to limit bandwidth use. I recently installed an Nvidia Geforce GT710 to my Microserver to assist with the transcoding.

Hi there, can you try increasing the in app quality setting a little bit? See if that had any impact. Thanks.

I started my tests with higher quality settings: 1080P 6 mbit, the results were the same. I lowered the quality setting to 144p when I realized the tests were eating through my mobile phones data subscription in no time

I would try 1 mbps.

That also gives the same results

Can you attach the ffmpeg log from that? Thanks.

Sorry, late reply. Been sick. Here is the log.

 

I noticed that when the video stalls, if I change the subtitles to the Off setting again, the video will resume playing.

@@mark235, what's happening is we are trying to extract your subtitles on the fly, and in your environment this appears to be taking a long time. This is what is causing the hiccup.

 

A couple options:

 

• Disable on the fly subtitle extraction in server transcoding settings. This will cause them to be burned in with server transcoding. This will hit your CPU hard so you may not like this either
• Use external srt subtitles

@@Luke, Ok, It's external subtitles then. Thanks for your time.
