如何在命令行模式下禁用 VLC 输出？

Question

当我在终端或控制台上vlc或cvlc在终端或控制台中播放音乐时，总会有这个（如下所示）不间断的输出阻止我通过按键发出命令ENTER。我想禁用它，我尝试vlc -q在相当模式下用switch启动 vlc，但它只去掉了[]括号部分，其余部分仍然存在并继续增长。

那么，如何让vlc完全不显示这些信息，仍然可以执行类似的命令行命令next，play，random等？

您应该能够通过管道 stderr 来摆脱库的输出

cvlc -q mymedia 2> /dev/null

至于命令，我不确定 vlc 是否接受来自普通标准输入的命令，但听起来 rc 接口可能是您正在寻找的。

cvlc -q -Irc mymedia 2> /dev/null
