HEVC not loading .ASS subtitles, but H264 has no issues.

[Nyhus 2]

Hello!
It seems from my extremely little testing that HEVC format direct playing on my Samsung Q70R TV does not load .ASS subtitles. I started questioning it when all my x264 had no issues, so I decided to convert my HEVC file to x264 and immediately it loaded the subtitles without issues.

Attaching logs for both, ffmpeg-remux is the x265/HEVC format, it seems to me that it loads the subtitles, but for some reason it does not visually show them while watching the show.
Whereas ffmpeg-transcode file is the x264 variant, where i have no issues. (For clarification I've attempted to force transcode on the HEVC file as well, but still subtitles refuse to show.

I fail to understand why this happens, so I am curious what you guys think?
Also Emby Theater on my PC has no issues with either file.

For the sake of clarity I've also attached a ffmpeg-transcode file of the HEVC.
It seems like libass is not initating/starting?

I think that was a bug in 1.6.4 that was fixed in later versions.  You can you test the latest USB Beta installation to confirm, or if you're not in a hurry you can wait for the next version in the app store which hopefully won't be too far away.

I see, I will update using the USB version later today and give it a test, will update here if it's works

That did seem to solve my issue! Thanks. I am noticing it takes some time before the .ASS subtitles end up showing, but I suspect that is just because they are .ASS subtitles?

It depends on the ass language and your tv year/model. Some foreign subs need to be loaded on demand which can take up to 40 seconds depending on your TV model.

Hi, Nyhus!

I want to know if your emby works well in displaying .ass subtitles without transcoding?

Yes, it does.
