我主要使用 mplayer 从 Linux 控制台播放音频文件。大多数时候，mplayer 很高兴地向我显示文件的持续时间和到目前为止的运行时间（注意：我暂停了两个播放只是为了让我复制/粘贴输出）：

您可以在上面看到，在 5404.9 秒中，我的时间为 16.4 秒，但更重要的是，我可以看到本例中播客的持续时间为 1:30:04.9。

这一集的不同之处在于弹出一个带有播客徽标的小窗口（Linux in the Ham Shack），因此 mplayer 似乎将其视为某种视频文件而不是普通的音频文件。但还要注意，输出确实不是不再显示文件的持续时间。事实上，文本显示完全不同。
我不需要文本显示完全相同，但我确实想查看剩余时间。有什么方法可以强制实现这一点吗？
如果您想要示例音频文件，我在 Ham Shack 第 150 集和第 203 集中使用了 Linux。 （除了作为听众之外，我与这个播客没有任何关系。）
我运行的是 Debian/Ubuntu/Mint，但操作系统似乎与此关系不大。
建议？谢谢！

只需禁用视频输出：
