Description of the problem:
I have several issues with subtitles:

  1. When using the web client and turning OFF burned subtiles (transcoding), ASS subtitles do not always load. Within the same playback session, some lines of the subtitles are displayed (with correct font as specified by ASS), but most lines are not displayed at all. The log files correspond to this case.
  2. When using the web client and turning ON burned subtitles, the subtitles load and sync well, but the font is messed up (see screenshot):

    In this sentence, 就请从窗口放心地观看吧, 请 and 观 is rendered using the fallback font 'NotoSansCJKsc-Medium.woff2', but the rest are rendered with an unknown font. To me this is very annoying and on the edge of being unusable.
  3. When using the Jellyfin Media Player the subtitles load and sync well but the ASS font is not used. Instead, the fallback font is displayed. This is my workaround for now.

Originally created by @xyttyxy on GitHub (Jan 17, 2022). Description of the problem: I have several issues with subtitles: 1. When using the web client and turning OFF burned subtiles (transcoding), ASS subtitles do not always load. Within the same playback session, some lines of the subtitles are displayed (with correct font as specified by ASS), but most lines are not displayed at all. The log files correspond to this case. 2. When using the web client and turning ON burned subtitles, the subtitles load and sync well, but the font is messed up (see screenshot): ![image](https://user-images.githubusercontent.com/10986475/149826010-4cc7e85d-6ea1-4574-a857-98ebb725605a.png) In this sentence, 就请从窗口放心地观看吧, 请 and 观 is rendered using the fallback font 'NotoSansCJKsc-Medium.woff2', but the rest are rendered with an unknown font. To me this is very annoying and on the edge of being unusable. 3. When using the Jellyfin Media Player the subtitles load and sync well but the ASS font is not used. Instead, the fallback font is displayed. This is my workaround for now. **Media Info of the file** ``` General Unique ID : 109378942591233352939692267230978065122 (0x52499E3AA25ADA5F8EAFADD8B0E342E2) Complete name : E:\Films\Anime & TV\Neon Genesis Evangelion\新世纪福音战士 S01E07 - A Human Work.mkv Format : Matroska Format version : Version 4 File size : 2.35 GiB Duration : 23 min 22 s Overall bit rate mode : Variable Overall bit rate : 14.4 Mb/s Encoded date : UTC 2015-11-04 12:07:51 Writing application : mkvmerge v7.6.0 ('Garden of Dreams') 64bit Writing library : libebml v1.3.1 + libmatroska v1.4.2 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High 10@L4.1 Format settings : CABAC / 6 Ref Frames Format settings, CABAC : Yes Format settings, Reference frames : 6 frames Codec ID : V_MPEG4/ISO/AVC Duration : 23 min 22 s Bit rate : 11.9 Mb/s Width : 1 440 pixels Height : 1 080 pixels Display aspect ratio : 4:3 Frame rate mode : Constant Frame rate : 23.976 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 10 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.320 Stream size : 1.95 GiB (83%) Writing library : x264 core 142 r2409+42 04be48a tMod [10-bit@all X86] Encoding settings : cabac=1 / ref=6 / deblock=1:-2:-2 / analyse=0x3:0x133 / me=umh / subme=9 / psy=1 / fade_compensate=0.00 / psy_rd=0.60:0.00 / mixed_ref=1 / me_range=32 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=18 / lookahead_threads=3 / sliced_threads=0 / nr=0 / decimate=0 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / fgo=0 / bframes=9 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=500 / keyint_min=1 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=crf / mbtree=1 / crf=17.0000 / qcomp=0.60 / qpmin=0:0:0 / qpmax=81:81:81 / qpstep=4 / ip_ratio=1.40 / aq=2:0.80 / aq-sensitivity=10.00 / aq-factor=1.00:1.00:1.00 / aq2=0 / aq3=0 Default : Yes Forced : No Color range : Limited Matrix coefficients : BT.709 Audio #1 ID : 2 Format : FLAC Format/Info : Free Lossless Audio Codec Codec ID : A_FLAC Duration : 23 min 22 s Bit rate mode : Variable Bit rate : 1 758 kb/s Channel(s) : 6 channels Channel layout : L R C LFE Ls Rs Sampling rate : 48.0 kHz Frame rate : 11.719 FPS (4096 SPF) Bit depth : 16 bits Compression mode : Lossless Stream size : 294 MiB (12%) Title : 5.1 Writing library : libFLAC 1.2.1 (UTC 2007-09-17) Language : Japanese Default : Yes Forced : No Audio #2 ID : 3 Format : FLAC Format/Info : Free Lossless Audio Codec Codec ID : A_FLAC Duration : 23 min 22 s Bit rate mode : Variable Bit rate : 678 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Frame rate : 11.719 FPS (4096 SPF) Bit depth : 16 bits Compression mode : Lossless Stream size : 113 MiB (5%) Title : 2.0 Writing library : libFLAC 1.2.1 (UTC 2007-09-17) Language : Japanese Default : No Forced : No ``` **Logs** This is only the tail of the server log: ``` [2022-01-17 10:49:21.549 -08:00] [INF] [34] Jellyfin.Api.Helpers.TranscodingJobHelper: Deleting partial stream file(s) "E:\ProgramData\Jellyfin\Server\transcodes\909694be6daced4610d962f84401eb51.m3u8" [2022-01-17 10:49:23.134 -08:00] [INF] [62] Emby.Server.Implementations.Session.SessionManager: Playback stopped reported by app "Jellyfin Web" "10.7.6" playing "Hedgehog`s Dilemma".

@nalsai commented on GitHub (Feb 1, 2022):

When not burning in Subtitles, Jellyfin uses JavascriptSubtitlesOctopus to display subtitles. Which, at least for me, sometimes doesn't load lines, is out of sync and many effects don't work properly.
With burned subtitles everything should work correctly as of 1.8.0.

It seems like the subtitles want to load a custom font, but the font is neither attached to the video (font isn't show in media info), nor installed on the server (font doesn't show when burning) or client (font doesn't show in Jellyfin Media Player).

I've never had an issue when using Jellyfin Media Player, because that uses mpv, which works correctly. If that doesn't display correctly, maybe there's something not right with your video file. Does it play correctly in mpv? Where does mpv get the font from?

Confirm that the fonts you intend to use contain 请 and 观? Behavious seems similar to that when fonts are missing.

Closing this issue as this specific problem appears to be an issue with the included custom fonts in the source file, and not an actual Jellyfin bug.
