Using ASS Subtitles Causes Every Video Trouble To Load

[NeverExists 21]

For some reason Emby and plex's latest update Causes my anime to have trouble playing. It keeps getting stuck on loading, then plays for a few seconds, then back to have trouble loading. It's nothing on my end I can assure you cause unticking burn in subtitles in the Nvidia Shield app fixes the problem, But I need those ASS Subtitles...…. Weird how both you guys and plex both have this same exact problem on the same exact update.... I have been using this exact setup for 2 years with no major issues like this.

What info exactly would you like? It's pretty simple! Any video file i try to play through emby that has ASS Subtitles  comes out choppy and unstable. I haven't changed my setup in years so it's not on my end. An example of a file would be all of them 8tb of anime that I can't watch cause they all have ASS Subtitles.

Sounds a bit too weird and accidental to me to be a likely cause.

Have you verified by going back to a previous Emby version where you are sure that it had worked?

Essentially, the transcoding is just running too slow. I'd rather suspect a system change or a driver change...

Nope everything is exactly the same. I switched to plex on the Nvidia Shield for 3 months to try it out, but every update got worse till the latest update a few days ago that made it so I couldn't use ASS Subtitles without constantly having to wait for the Server to catch up or whatever. I then unplugged all my hard drives from my shield, where the server, app and files were stored and moved them back to my laptop where I had it before switching to plex. So I don't see how 2 different apps and 2 different servers o n 2 completely different systems has anything to do with one another except what I implied. Weird how on my shield and on my laptop both issues which is the same issue, were fixed by not using ASS Subtitles which causes transcoding. 2 completely different apps on 2 completely different systems had the same exact problem and were fixed by the same exact way.

 

The App is on my NVidia shield and the server is on my laptop. I'm trying to reinstall it after I leave the beta program. I will update.....

So you had Emby always and only on your laptop and the other one always on the Shield only, and Emby on the Laptop has worked well earlier and the other one had worked well on the Shield earlier?

[NeverExists 21]

yes

[NeverExists 21]

Now I switched back to my laptop and updated the server and started experiencing the same exact issue. It even gets stuck at the same places using both apps, plex and emby. Unticking Burn in ASS subtitles in both apps fixed the problem both times.  Also using the web app on my laptop where my server and files are located seems to work fine.

[softworkz 5066]

OK, thanks, that changes theories of course..

In both of the log files you have posted, you are playing H.264 files with High10 profile and a color format of yuv420p10. This is rarely used and not supported by most hardware decoders, so the decoding is happening in software and the decoded frames are then uploaded to hardware for burning-in the subtitles.

Could you try an H.264 video with normal (8bit) color format (but ASS subs of course) and see how that compares?

[softworkz 5066]

You can see the color format in the media info at the bottom of the page:

Can't be my Wi-Fi cause I had the problem when my hard drives were plugged into the shield and was not using Wi-Fi. Also it works with the webapp on my laptop where my hard drives are now plugged in.

Will do 1 sec

It's hard to find in the world of anime cause almost all Anime is this same format. And ones I do find that are 8bit, they don't have ASS Cause only The Seasoned Encoders all use 10bit and ASS. Anime is famous for using ASS and the fact that it does not work with anime is really weird also the fact that you said the color and bit were weird when A very large community all use it as the main go to for there encodes says a lot. Unless I didn't understand correctly. I constantly had issues through out the years with emby and my Anime collection cause obviously you guys rather have no clue about how type of files that mainly use ASS or None of you guys use it for properly encoded Anime.

See that's the thing with Anime, Its all 10 bit. I've just looked at 30 different shows I have and they're all 10 bit. The only shows I have that are 8 bit don't have ASS

Are all H.264-10bit?

HEVC-10bit for comparison would be fine as well.

Almost all are 264 10 bit yes. All the millions of releases are about 94% 264 10bit. I might haave a HEVC just 1 sec

OK, let's try the following:

• Please install the Diagnostics plugin from the plugin catalog
• Restart Emby Server
• Go to Diagnostic Options as shown in the screenshot below and disable hw subtitle overlay
• PRESS Save at the bottom
• Retry playback

Here you go. BTW If I tried to restart the server after choosing that option in diagnostics, it would just reset the option so when emby restarted it was unchecked. It didn't do this the last time. Just hitting save then playing the file returned the same results as the other time with the green and pink screen.
