Subtitles working for one episode then disappearing.

[Mkilbride 76]

So my friend is using Emby Theater to watch one of my shows with .ass subtitles.

 

The Subtitles show for one episode. Then none of the rest have them. I then I have to restart my PC, each episode. What could cause this?

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. thanks !

Here's a log file. If she goes back to the previous episode, it has subtitles, but the next one does not. Very strange.

Those are AVC Hi10p encodes and they're always a headache. You'd be better converting them to 8-bit AVC or any HEVC. Since decoding is done in software only, graphic subtitles might be too taxing for your CPU, as it simply cannot keep up, especially if you FF/REW during playback and not play it straight through. 

Edit: Since your friend is using Theater as a client, you could increase bandwidth limit and not transcode but pass her direct file, see how does that compare.

Edit2: Although, per that "max bitrate" limit, it's likely that client has playback settings on "Auto", tell her to change "Internet quality" in Settings>Playback to some fixed value, like "4K-120 Mbps".

And the ffmpeg logs? When you attach them please indicate which ones had subtitles and which ones did not. Thanks.
