`dshow` only applies on Windows. Are you on linux?

I apologize. Yes, I run linux and I had learned that dshow is only for Windows. I've saved a number of web pages with example for various ffmpeg tasks and most don't specify that they apply to one OS only.

I've read through the 62-page FFmpeg doc. It's a great reference but not so good a teacher for someone new to video production. I joined the mail list but there seems to be no traffic on it. I hope here is where I can learn what I need to be productive.

Using
ffmpeg -i /dev/video0 -i pulse -c:v copy -c:a aac output.mp4 

results in:

pulse: No such file or directory

How do I specify the webcam and headset mic to record a video?
