How to install:
1. put this file on lua/intf/
2. enable extra interface: luaintf (Settings[Show all] -> Interface -> Main Interfaces -> extract modules='luaintf'[make the 'Lua interpreter' checked])
(important: extraintf=luaintf not lua)
3. set lua interface to this file name: All Settings -> Interface -> Main Interface -> Lua -> Lua interface = lyrics
4. Settings - subtitle/osd - make "enable osd" checked.
如何启用:
1、将本文件放在 lua/intf/ 文件夹下
2、设置(显示所有)-界面-主界面-扩展界面,填入 luaintf,并勾选 Lua interpreter(勾选会自动填为 lua, 需要手动改成 luaintf)
3、设置(显示所有)-界面-主界面-Lua,在 Lua 界面 字段填入本文件名: lyrics
4、设置-字幕/OSD-确保 "启用 OSD" 勾选,下方可以设置字体

按照介绍的方法:
1、将本文件放在 lua/intf/ 文件夹下
2、设置(显示所有)-界面-主界面-扩展界面,填入 luaintf,并勾选 Lua interpreter(勾选会自动填为 lua, 需要手动改成 luaintf)
3、设置(显示所有)-界面-主界面-Lua,在 Lua 界面 字段填入本文件名: lyrics
4、设置-字幕/OSD-确保 "启用 OSD" 勾选,下方可以设置字体
在flac文件标签里的歌词还是不能显示,选可视化的时候,提示未找到歌词,不知道自己哪里弄错了,来请教

  1. 麻烦贴下文件路径
    Mac 的路径类似这样:/Users/用户名/Library/Application Support/org.videolan.vlc/lua/intf/lyrics.lua
  2. 扩展界面
    image
  3. 启用插件
    image
    启用后在插件管理器能看到
    image
  4. 启用字幕
    image
  5. 打开可视化的效果
    image

如果还是不行,可以看下日志,【窗口】-【消息】打开日志界面,在过滤输入框中输入 [lyrics] 查看插件日志

作者,你好
我是VLC 3.02 win10版本
我也是使用这个插件显示未找到歌词
QQ图片20231130172610
QQ图片20231130172622
经排查发现是中文问题,我播放英文歌曲可以正常显示歌词
QQ图片20231130172628
必须要满足mp3和lrc文件名称为英文,同时lrc歌词也要为英文方可正常显示歌词,这应该是编码问题,请问大佬有办法解决吗,非常刚需这个插件,谢谢!

@Bigxxi 你好,可以把日志级别调整为debug看下。也可加微信交流:Youth_Lin

问题:在 Windows 环境中,lrc 路径包含中文(Non-Ascii字符),使用 lua 原生的 io.open 会报错 invalid argument
解决:使用 vlc.io.open 即可,vlc 内部封装的这个函数入参为 UTF-8 字符串,支持中文
脚本已更新

vlc 内部如何支持非 ASCII 字符的:

// vlc.io.open 的 C 实现【1】/modules/lua/libs/io.c
static int vlclua_io_open( lua_State *L )

// vlclua_io_open 调用 vlc_fopen【2】/src/text/filesystem.c
FILE *vlc_fopen (const char *filename, const char *mode)

// vlc_fopen 调用 vlc_open【3】/src/win32/filesystem.c 【4】
int vlc_open (const char *filename, int flags, ...)

// 调用同文件 widen_path 函数【5】/src/win32/filesystem.c
static wchar_t *widen_path (const char *path)

// 【6】include/vlc_charset.h
VLC_USED static inline wchar_t *ToWide (const char *utf8)

// 【7】是 windows 提供的 api
MultiByteToWideChar

顺便补充一下,如果有朋友使用外挂lrc文件在windows上无法显示中文歌词,需要将lrc文件改为utf-8编码,并且要在设置-字幕/OSD-字体改为【Microsoft YaHei UI】,部分中文字体也会导致歌词失效
