如何让 mplayer 使用字幕？

我正在尝试按以下方式在 mkv 文件中使用字幕：

mplayer video.mkv
mplayer -sub video.srt video.mkv
mplayer video.mkv -sub video.srt

但只播放了视频，没有字幕。播放视频时我还按了几个按钮（“j”、“u”、“s”），但没有任何变化。

操作系统：MacOS 10.13.16 mplayer：1.3.0-4.2.1

也许我遗漏了什么？或者mplayer必须以某种特殊、复杂的方式进行编译？或者缺少库？或者是因为它是 Mac？

有没有办法将 srt 文件中的字幕与 mkv 视频一起使用mplayer？

我已尝试按照评论中的建议设置配置，如下所示这里mkv。但是我在播放与srt文件在同一个文件夹下的文件时出现以下错误：

Warning unknown option subfont-text-scale at line 3
Warning unknown option subfont-osd-scale at line 4
The fontconfig option can't be used in a config file.
Error parsing option fontconfig=yes at line 5

srt 文件中的前两个条目如下：

1
00:00:00,000 --> 00:00:05,000
<font face="Hiruko" size="38">Test</font>

2
00:00:05,000 --> 00:00:14,060
<font face="Hiruko" size="38">Subs: English</font>

当前内容.mplayer/config：

# Write your default config options here!
subalign=2
font = "Arial"
subcp = iso8859-1
# Set font.
#font=/home/osmo/.fonts/microsoft-vista/calibri.ttf

# Set font encoding.
subfont-encoding=unicode

# Set subtitle file encoding.
unicode=yes
utf8=yes

当我按如下方式播放文件时

mplayer -v video.mkv

视频播放正常，音频正常，但没有字幕。控制台中的输出如下：

答案1

你可能mplayer没有freetypefontconfig

Configuration: --cc=clang --host-cc=clang --disable-cdparanoia --prefix=/usr/local/Cellar/mplayer/1.3.0 --disable-x11
Configuration: --enable-gpl --enable-postproc

可能的解决方案：

  • 安装位图字体mplayer 网站并将其解压缩到~/.mplayer（有关详细信息，请参阅mplayer 文档

  • 您说您安装mplayer了brew。mplayer再次安装freetype和fontconfig支持。

    卸载mplayer并：

    brew install freetype
brew install fontconfig
brew install --build-from-source mplayer

    理论上mplayer可以检测fontconfig并freetype启用它。

编辑：

要列出所有可能的标志，请使用：

brew info mplayer

答案2

部分答案：

mplayer我尝试使用test5.mkv带有字幕的文件进行自制安装matroska 测试套件（以使结果可重复）。

就像在您的日志中一样，我收到了错误消息Cannot load bitmap font 'Arial'，而其他日志消息表明字幕轨道本身已被正确识别。

所以问题似乎出在加载字体上。我尝试了一些变体-font（包括路径和字体配置模式），有和没有-fontconfig。我还安装了原始位图字体由 mplayer 提供。我也尝试创建subfont.ttf符号链接。它总是抱怨无法加载位图字体，无论它真的是原始位图字体还是 TrueType 字体。

我还发现，虽然 Homebrew 被列为fontconfig依赖项，但它mplayer在启动时会抱怨-v -v它不是在启用 fontconfig 的情况下构建的。

所以，所有这一切似乎表明，自制软件由于某种原因被破坏了。

对于我来说，下一步（如果我需要 mplayer）将是从源代码编译 mplayer，并找出 homebrew 装瓶时是否存在配置错误，但我不确定你是否愿意（或可以）走这么远，如果我应该成功的话。

另一种选择是向管理自制啤酒配方的人投诉，并让他们调查此事。
