iOS透過USB lightning外接裝置(串流視訊),不用過MFI認證(usbmuxd方式下的peertalk)

目前iPad iPhone等iOS要連接外面的裝置

如 wifi 路由器, wifi ip camera, iOS專用隨身碟, 傳輸線等等

大概連線方式就是如下圖所示

大概分成幾大類

使用iPhone當成外接HDMI攝影機給電腦OBS STUDIO直播使用

用iphone內建的照相機，當成外接的攝影機，
由電腦OBS做直播

為何不直接用app facebook直播就好
幹啥多此一舉？

用電腦OBS stduio第三方直播軟體來直播，
可以做出一些附加價值的玩意
比如：
1.插入多支攝影機進行轉場
2.上跑馬燈
3.畫中畫
4.去背
5.上logo

以上的功能,app facebook 是無法達成的，
要用電腦OBS才能達成

要找一個app, 可以呈現乾淨的畫面
（ 不要有對焦畫面不要有案件　不要有快門等等)






使用工具:

1. FEBON180 UVC HDMI 擷取器

2. lightning 轉HDMI轉接器

將電腦連接FEBON180 HDMI擷取器，經由電腦OBS擷取

我希望打開iphone相機app後，可已呈現這樣的畫面
