YouTube streaming typically involves a camera with an HDMI output, a USB3 HDMI digitiser, and a suitably beefy PC to run it all. It’s quite a process, and for [Coreymillia], more complex than it needs to be. He’s come up with something simpler, a dedicated self-contained streaming rig using a Raspberry Pi 4.

As you might expect it uses the Raspberry Pi HQ camera at the optical end, but it’s the software surrounding it that transforms it from a mere camera into a streaming rig. There’s a web based user interface, but perhaps more interesting are the companion dashboard peripherals. A Raspberry Pi or an ESP32 Cheap Yellow Display can both serve as a small in-view dashboard and controller.

We know from experience that a stream can be a difficult thing to get right even with high-end hardware, and we’re interested to see this standalone device allowing , we hope, an easier way to do it. If you’re a streamer we’re guessing you’ll be taking a closer look. Even so, this is surprisingly, not the simplest Raspberry Pi based streaming device we’ve seen.

YouTube 直播通常需要一台带 HDMI 输出的相机、一个 USB3 HDMI 采集卡，以及一台足够强悍的 PC 来运行这一切。过程相当繁琐，而对 [Coreymillia] 来说，这比实际需要的要复杂得多。他想出了一个更简单的方案：一款基于 Raspberry Pi 4 的独立一体化直播设备。

正如你所料，它光学端采用的是 Raspberry Pi HQ 相机，但真正将它从一台普通相机转变为直播设备的，是其配套的软件。它提供了一个基于网页的用户界面，但更有趣的是配套的仪表盘外设。无论是 Raspberry Pi 还是 ESP32 Cheap Yellow Display，都可以作为小型可视仪表盘和控制器使用。

根据经验，我们知道即使使用高端硬件，要搞好一场直播也可能很困难。我们很感兴趣看到这款独立设备能否（我们希望如此）提供更简单的方法。如果你是一名主播，我们猜你会仔细研究一下。即便如此，令人惊讶的是，这并不是我们见过的最简单的基于 Raspberry Pi 的直播设备。
