💖 dc1394_vloopback — the manual page, bestie edition ✨

okay so you found dc1394_vloopback and you're like "what is this" — don't worry, I got you. This is a page from the User Commands manual, section 1, and it's all about yeeting format0 video into a V4L vloopback device. Let's get into it 🎀

🌸 NAME 🌸

dc1394_vloopback — send format0 video to V4L vloopback device 💅

✨ SYNOPSIS ✨

dc1394_vloopback [--daemon] [--pipe] [--guid=camera-euid]

[--palette=yuv422|rgb24] [--width=n] [--height=n]

🦋 DESCRIPTION 🦋

It sends format0 640x480 RGB to the vloopback input device, so that V4L applications can consume it on the vloopback output device. That's the whole plot, no cap. 👑
