从命令行运行 VLC 播放器时如何修复这些警告消息？

  • 772

我使用 Homebrew 在 macOS 上安装了 VLC 播放器，然后从命令行运行它时，我收到了许多消息/警告：

% which vlc
/usr/local/bin/vlc
% vlc
VLC media player 3.0.16 Vetinari (revision 3.0.16-0-g5e70837d8d)

...

和这个：

% which cvlc
cvlc not found

知道如何解决它们吗？

macos command-line

    事实证明，从带有接口规范的命令行运行 VLC 播放的语法是使用--intf(or -I) 选项：

    vlc --intf <name_of_interface>

    其中接口的名称可以从给出的列表中选择

    vlc -l | grep -iF interface
VLC media player 3.0.16 Vetinari (revision 3.0.16-0-g5e70837d8d)
18:  macosx                 Mac OS X interface
21:  ncurses                Ncurses interface
127:  oldrc                  Remote control interface
140:  lua                    Command-line interface
144:  lua                    Lua Playlist Parser Interface
160:  dummy                  Dummy interface
202:  motion                 motion control interface
353:  hotkeys                Hotkeys management interface
370:  gestures               Mouse gestures control interface

    例如，不使用接口：

    vlc -I dummy my_audio.mp3

    使用文本界面是：

    vlc -I lua my_audio.mp3

    事实

    vlc my_audio.mp3

    给出一个警告，提示 'cvlc' 似乎是一个过时的命令名称。
