我最近一直在使用liquidsoap，试图为在线广播电台设置自动流媒体。 到目前为止一切正常，除了我需要一种方法来让所有文件具有相同的响度，因为它们将来自许多不同的人并将跨越至少五十年的发布日期，所以我期待它们被掌握到很多不同的响度级别。
问题是，当我尝试添加任何提供的ReplayGain实现（enable_replaygain_metadata()和replay_gain: - 协议）时，我得到Source failed (no more tracks) stopping output...，即使我实际上没有使用任何ReplayGain值。
我已经检查了相关脚本（/usr/lib/liquidsoap/1.1.1/extract-replaygain）和脚本调用的二进制文件（mp3gain），他们都回馈了我期望的结果。
但是，由于enable_replaygain_metadata()和replay_gain: - 协议都没有得到很好的记录，我不知道他们实际期望的返回值是什么，或者他们的行为应该是什么。由于我找不到有关原因的任何有用信息，因此到目前为止在线搜索解决方案相对没有用，我发现所有信息都告诉我这个问题不应该发生。
非常感谢任何有关此问题的帮助。

编辑：
检查我的目录中是否有错文件导致mp3gain失败或返回垃圾后，我发现了以下内容：
显然，enable_replaygain_metadata()在我使用single()或playlist.safe()作为来源而不是playlist()时效果很好，所以我猜它只适用于本地文件，这与文档所说的完全相反。但是，playlist.safe()必须检查启动时找到的每个文件，因此需要一些时间。
有没有办法让这项工作符合标准playlist()？
