内封字幕显示不了

z-x-f commented 1 week ago

您好，我的搭建环境是使用的cd2挂载，然后auto_symlink生成strm，strm指向的是本地文件。现在直链播放都正常。现象是有些内封字幕的视频，通过浏览器播放的时候没字幕，但是没字幕的时候也不一样，有的可以选字幕但不显示字幕，有的直接没字幕选项。通过windows emby theater播放的时候，上面web播放有选项没字幕的，可以正常出现字幕，web播放无字幕选项的，emby theater也没有。而这些视频通过infuse添加emby服务器播放的时候，都可以正常显示字幕。求助这些不能显示字幕的视频我该从哪方面排查问题呢？谢谢！

关了签名后发现emby theater可以正常显示字幕 web还是不行， https://192.168.1.33:8443/emby/Videos/76022/4a6a991475e32085e4f10cc135010798/Subtitles/2/0/Stream.ass?api_key=8309b6e4996f498a909054bd457cc3ec 这个一直正在处理

字幕这块其实老大难问题了，从脚本一开始就是这样，根本原因在于 emby 官方客户端对于内封字幕或外挂字幕的支持很局限，它是通过https://192.168.1.33:8443/emby/Videos/76022/4a6a991475e32085e4f10cc135010798/Subtitles/2/0/Stream.ass?api_key=8309b6e4996f498a909054bd457cc3ec这样的接口分离处理的，而内封字幕emby 的处理更加奇葩，调用字幕接口时是由服务端访问这个媒体文件，从媒体内部使用FFmpeg提取为单独的字幕文件并返回的，在 rclone/cd2 挂载媒体的环境下是没问题的，提到的关了签名后发现emby theater可以正常显示字幕，这个应该是STRM下特定出现的了，原因也是调用字幕接口时是由服务端访问这个媒体文件，而web还是不行这个不知道是否是测试时被脚本中字幕缓存所影响，可以重启emby服务端和nginx试一下，排查方法的话，基于调用字幕接口时是由服务端访问这个媒体文件来说，emby 服务端日志中应该有详细信息，例如关了签名后发现emby theater可以正常显示字幕之前，日志中应该有字幕提取之类的报错信息

开了签名果然日志里有报错了

关闭签名后，重启emby、清空nginx缓存，web看内封字幕还是不行，~~不过外挂字幕倒是没问题。。。。~~

我也发现了这个问题，我测试使用软连接，但是CD2软连接emby读取不到软连接文件？内外都映射路径都是相同的。奇怪，进emby 容器内查看是显示 ??? 这是咋回事呢？

我发现使用yamba播放器可以正常显示字幕，你可以试试

bpking1 / embyExternalUrl
