nodiaque 44 Posted March 9 Posted March 9 Hello, I have an ongoing issue with ASS Subtitle. I think I opened an issue on that in the past but I can't find it. What happen is part of the subtitles don't show when it's in ASS format. Sometime, it also add some artifact like /t2334534 or (ED) at the end of each line. It only happen on my LG TV (OLED65C8PUA). When I play through web browser, android, pc or anything else, the subtitle are there for these parts. I tried disabling "Allow subtitle extraction on the fly", which make it transcode and burnin into the video. But the result was worst, I had no subtitle at all. I tried all option under advanced --> subtitles and none change anything. Whatever prefer option I choose changed nothing, it seems only the part under transcoding was being used. TV: PC TV: PC Thank you! ffmpeg-transcode-a30bf43d-5216-4cdf-a234-5f13d5d38824_1.txt ffmpeg-transcode-3a2d95b0-4173-497a-b053-06d9638b4f69_1.txt ffmpeg-transcode-0bb336ab-708c-467f-abaa-27d25591cd77_1.txt embyserver.txt
SamES 1004 Posted March 9 Posted March 9 ASS formatting and rendering can require quite a lot of processing, often more than a TV device can provide, particularly when there are complex subtitle animations. ASS support is not native on the TV, so they need to be processed and manually rendered by the Emby app. Unfortunately, there are some limitations to what ASS commands are supported, and I suspect what you are trying to do may not be fully supported.
nodiaque 44 Posted March 9 Author Posted March 9 But shouldn't burnin solve all of that? I'm far from having not enough horse power on that server. Quadro RTX 4000 with Xeon w-2275.
visproduction 283 Posted March 9 Posted March 9 Nod, Try turning off the text shadow in your ASS. You may need to extract them, if they are embedded. Also remuxing the media without the embedded ASS subtitles would be advised. The shadow has to probably be scaled to fit the TV and that may result in the custom placement subs just being ignored. ScaledBorderAndShadow: No Hope that helps.
nodiaque 44 Posted March 31 Author Posted March 31 So, I tried something. Installed Jellyfin and played the same file. Well, everything work as expected. No change to subtitle. Looking at the server, it doens't remux or anything, it says that it's sending everything directplay like emby. So there's something with Emby player not working properly if it's working correctly in other player without transcoding (and no burn-in).
visproduction 283 Posted March 31 Posted March 31 (edited) Nod, Could it be the transcoding settings? Maybe you have Emby set to transcode sooner (with files that are large or with certain codecs) than Jellyfin. If the settings are different, you would expect the software and hardware encoding to act differently. Part of the problem is perhaps many of the settings for both, are sort of short hand abbreviations of other, more detailed settings. When you set to one level, there could be 8 other more detailed encoding settings that move up or down, together. There are just too many possible encoding settings, so they are grouped together to make it easier for users. It becomes very difficult to see if both services are doing similar things, unless you dig down and look compare the ffmpeg command lines. I don't use transcoding with either system, so this is more of an outside comment. I hope that makes sense. Ha! Edited March 31 by visproduction
nodiaque 44 Posted March 31 Author Posted March 31 There is no transcoding, it's direct play in both part. I tried using burn-in on emby and it result in no subtitles. I tried extracting the subtitle and it didn't solved. I've tried all of the option both under transcoding and subtitle option and the result are always either no subtitle at all (I tried watching the whole 30 minutes show and never had anything showed) or missing sub Jellyfin is a brand new installation. I did nothing and it worked out of the box (outside of enabling hardware encoding/decoding). Jellyfin also send it to my tv without any transcoding. So since there's no transcoding or remuxing of any kind and no burnin, it's not a codec configuration. It's something the emby player or server isn't sending or processing properly. 1
SamES 1004 Posted March 31 Posted March 31 Have you updated the server to the latest release and retested with transcoding? Via a PM you can send me a link to a file that has issues, just let me know what time the invalid/extra text appears in the subtitles?

SamES 1004 Posted May 25 Posted May 25 I believe it should be in the next store update, whenever that occurs.
ABOhiccups 2 Posted May 27 Posted May 27 I have the same issue with ASS Subtitles on LG C2. Jellyfin never have that issue on LG C2. When I try to play an Anime movie with ASS Subtitles attached to MKV file. It won't play. Even with "Extract Subtitles on the fly" is enabled. It does play but there's no subtitles displayed.
nodiaque 44 Posted May 27 Author Posted May 27 Yeah all the setting to extract, convert, use ocr doesn't do anything on the lg. It always just send it to the tv. With some other option, it disable the subtitle totally. While jellyfin doesn't have problem, I do have other problem with jellyfin. Like halfway through an episode, it freeze. I even get out of memory error. I can play about 1m5 episodes before it start that behavior. It's weird since it also direct play the subtitle. Since jellyfin is currently my backup only for Dolby vision while we wait for emby to enable onthefly mp4 remux of video, that's mostly why I use it. At least, I manage to find some srt subtitles of the anime I'm watching right now, but it's now always possible
nodiaque 44 Posted May 27 Author Posted May 27 I don't have the problem with the browser on edge. The screenshot above were taken with edge. Unless something changed since I did the test.
nodiaque 44 Posted May 27 Author Posted May 27 The issue from this thread is not that it's not playing. The issue in this thread is part of subtitles not playing. It happen often when it's other style, font or more graphical. Music animated subs always were hit or miss. If you check my screenshot, we can see what kind of subtitles are missing. Outside of these, the subs work. Problem is I'm watching Dr. Stone so everytime there's extra subtitles (which is ten billion time each episode), I lose all subtitles while its suppose to be showed.

Hi, yes that's what we've been looking at. Thanks.
nodiaque 44 Posted May 27 Author Posted May 27 No problem Luke, I see you either cleaned the thread or the other person deleted his message. 1
Luke 40106 Posted July 2 Posted July 2 58 minutes ago, nodiaque said: was wondering if it was part of the 1.0.47 update? Hi I’m not sure but it would be helpful to know if anything has changed with it. Thanks.
nodiaque 44 Posted July 2 Author Posted July 2 I did try to play the same file and there's a big improvement on subtitles overall. What I mean is often, subtitles would lag when skipping, now it seems to just go where it should properly. I also saw that I now have subtitles on the parts I identified so it's better. I'll report if I find something else. Thanks! 1
Kwakx 2 Posted July 2 Posted July 2 (edited) 3 months of waiting and we are almost there.... I have the same problem, the fonts load but the ASS subtitles lag a lot and at the beginning of the playback even do not display at all. It also looks like the subtitles start working after some time of playback, and I guess it also depends on the complexity of the subtitles. Edit: I checked and after starting a given video with ASS subtitles in my case emby loads them about 7s. I have a video that from 1s has subtitles that display only after 7s. Once they are displayed and I go back to 00:00 there is no problem anymore Edited July 2 by Kwakx 1
nodiaque 44 Posted July 3 Author Posted July 3 (edited) It seems the \fade(x,x) metadata in subtitles aren't always converted LG: PC: Edited July 3 by nodiaque
SamES 1004 Posted July 3 Posted July 3 Can you please PM me a copy of the ass file and the approximate time of that subtitle? Thanks
