我的ffmpeg命令识别我的音频输入设备需要什么？
以下参考文献无法帮助解决我的问题：enter link description here
我想在捕获屏幕活动时记录我（与Windows笔记本电脑交谈）的谈话。虽然我成功捕获了屏幕上的内容（通过从命令中删除了所有提及的音频），但是由于捕获的设备无法被ffmpeg识别，因此我无法捕获音频。 （我通常使用默认的笔记本电脑来向Audacity输入音频...当然，在此ffmpeg命令中也有使用它的方法。）
我的音频设备：
ffmpeg -list_devices true -f dshow -i dummy

通过注册表编辑器找到全名：麦克风阵列（IDT高清晰度音频编解码器）
为什么找不到音频输入设备？

audio=Microphone Array (IDT High Definition Audio CODEC): I/O error
Gyan是正确的。使用DirectShow列表中报告的截断表达式有效。
audio="Microphone Array (IDT High Defi"
