我使用以下链接中的技巧并能够将音频录制到文件 中使用 PulseAudio 录制程序的输出

我一直在调整命令并尝试将字节流式传输到 UDP 服务器。这是我到目前为止所得到的，但它不起作用

parec -d sink_name.monitor | ffmpeg -re -ac 1 -f s16le -ar 16000  -i - - | ffmpeg -re -i - -f mpegts udp://localhost:20001
  1. 第一个命令提供音频流
  2. 此命令部分用于将流存储在 .mp3 文件中，请参阅ffmpeg -ac 1 -f s16le -ar 44100 -i - test.mp3
  3. 这应该将流重定向到 UDP - 从ffmpeg -ac 1 -f s16le -ar 44100 -i - test.mp3

我可以在这里使用一些帮助。提前致谢！

我尝试通过 snap 和 apt 安装 Visual Studio 代码，在这两种情况下它都不起作用。击中后请参阅下面的跟踪code --verbose。

其他观察 -

  1. 它适用于sudo code --user-data-dir它只是不正常。
  2. 从应用程序-> 启动器图标尝试时，会出现空白窗口。
  3. 似乎不是--disable-gpu很多人面临的问题
