10年前，我写过一篇文章，给大家介绍了一下如何用最低的成本转播PlayStation 4到国内的直播平台。简单来说，就是用PS4自带的直播功能，推流到twitch，并使用树莓派截取信号并重新推送到其他的直播平台。这样做的好处是，不需要购买昂贵的视频采集卡，只需要一个树莓派就可以了。
10年后，我又有了类似的需求，只不过这次，我想做的是自己搭建一个直播服务来输出视频信号，这样，无论我身处何地，都可以通过网络来观看自己的视频。
当然，和10年前不同的，这次我购买了昂贵的视频采集卡，以及新的树莓派。并且，当时我研究了很久如何配置服务器之类的，这次chatgpt帮我一波搞定，并且连脚本都给我写好了。稍微调整一下就能用。所以也在这里分享给大家。这次的思路是，用树莓派搭建一个RTMP服务，然后用我的台式机将视频采集卡采集的内容通过OBS推给树莓派，这样我就可以通过VLS甚至浏览器直接观看内容了。
