DJI Pocket 3 直播應用! dji pocket 3轉hdmi連接電視或導播機

dji Pocket 3關於直播應用有兩種物理接口
1. 有線 USB-C webcam輸出
2. 無線 RTMP 直播輸出

分享dji pocket3直播過程中攝影機功能是否正常使用?

1. 橫式直播時候: 不管uvc webcam或pocket3直接直播，都是正常模式

2. 豎屏直播時候 uvc webcam 模式: 仍然輸出1920x1080 1280x720 等橫式畫面，是採用左右補黑邊方式 dji pocket 3直接直播: 支持豎屏模式,臉書直播和youtube直播是真的是直式的. ( 不是左右補黑邊)

3.人臉跟隨功能不管是uvc webcam輸出或直接直播, 都有支持人臉跟隨直播後 (或變成webcam後), dji pocket3搖桿連續快速按兩次，就會變成人臉跟隨

uvc 輸出可以連接電腦，電腦端的OBS 或視訊會議軟體可以直接直接抓到影像
rtmp輸出是直接在dji pocket 3上面做直播, 透過app控制做youtube直播臉書直播或rtmp

1.有線 USB-C webcam輸出

dji pocket 3電源打開，連接usb數據線至電腦

然後,usb線材連接電腦時候，dji pocket 3會出現提示選單

請選擇網路攝影機這個按扭！

這時候可以打開電腦GOOGLE meet , OBS等等軟體

將dji pocket3轉hdmi

dji pocket 3沒有實體的hdmi 輸出接口，

亦可以利用usb webcam 輸出功能，將uvc轉成hdmi

產品1：連接FEBON 羅技攝影機轉hdmi轉換器

購買連結： https://www.febonstore.com/products/logitech-cam-to-hdmi-output

將DJI Pocket 3轉成HDMI 輸出後, 就可以連接電視

連接電視的目的就是能夠接hdmi 視訊導播機～

產品2: USB攝影機視訊轉換器

連結：https://www.febonstore.com/products/uvc-streaming-adapter

usb攝影機視訊轉換器，除了將uvc訊號轉hdmi之外，亦還有更多有用功能

比如: uvc bypass輸出，錄影至usb ssd card, iOS上直播使用等等

連接至usb webcam輸入

除了hdmi 輸出之外，還有更多有用功能

dji pocket3 連接導播機

除了接導播機之外，還可以連接電腦 , ipad, 錄影等等

並非市場上所有的uvc to hdmi都能相容 dji pocket 3

<2023/10/31 市場資訊>

並非所有市場上的UVC to hdmi轉換器都能成功連接dji pocket 3.

2.無線rtmp直接直播

dji pocket 3 雖然可以直接面對yotube facebook的選單，

但是不建議直接直播使用

目前dji app無法直接做臉書直播，然後做youtube直播會變成排成直播

我建議採用restream.io方式來達成

想法是這樣

dji pocket 3 ----> 直播至restream.io --->面對youtube 和facebook

同一時間，就可以雙直播！而且不需要太大的折騰

打開dji app

採用rtmp方式直播，將restream.io的 rtmp和金鑰貼上此欄位

第一次設定需要貼上rtmp和金鑰, 第一次比較麻煩一點

第二次以後直播就不需要這樣，直接就直播就可以了～～

利用RTMP直播方式，亦可以將dji pocket 3變成無線的hdmi

這個直播是內網的直播

將dji pocket的rtmp串流直播到rtmp轉hdmi轉換器，

轉換器收到rtmp訊號後，自動轉成hdmi 輸出

需要準備路由器～

dji pocket 3-----> 直播到rtmp轉hdmi轉換器--->變成hdmi輸出

影片中有詳細設定

dji pocket 3轉成無線hdmi，連接電視！

無線要擔心的是干擾風險，採用無線可能會受到附近2.4g干擾會卡頓

方便使用無拘束和干擾就是一個蹺蹺板

若是怕干擾問題，可以採用剛剛的uvc to hdmi方式，這個就保證穩定

當然也可以連接hdmi視訊導播機 atem mini pro

Turn dji Pocket 3 into HDMI & connect to TV and atem mini pro

Turn dji Pocket 3 into HDMI

There are two ideas that turn dji pocket 3 into hdmi output.

one is that convert a USB UVC webcam output, like what the DJI Osmo Pocket 3 and DJI Osmo Action 4 are using to HDMI.

the second is that convert wireless local rtmp into hdmi output!

For live streaming application of dji pocket 3, it have two interface

1. usb-c UVC output. -> wire uvc to hdmi

2. rtmp streaming. -> wireless rtmp to hdmi

How to turn dji pocket 3 into HDMI ?

There are two idea !!

1. Turn USB-C uvc of dji pocekt 3 into HDMI

1.1. FEBON Logitech webcam to hdmi adapter

LINK : https://www.febon.net/products/febon-logitech-webcam-to-hdmi-converter

dji pocket 3 connect to this adapter

1.2. USB webcam streaming adapter

DJI pocket 3 uvc output connect to this adapter

https://www.febon.net/products/usb-webcam-streaming-mulitimedia-adapter

this adapter have many output. one of it is HDMI output

it also can let DJI pocket 3 connect to iOS and pc at the same time.

By the way,

in amazon , you can see some China UVC to hdmi adapter

eg: O brand , R brand ..

Lead user share the information that Dji pocket 3 CAN NOT work on O brand , R brand.

the adapter firmware do not match

you can see faceobok group " DJI OSMO POCKET / POCKET 2 / POCKET 3 User Group"

2. Turn rtmp of dji pocket 3 into HDMI

dji pocket 3 can do the live streaming .

for example: Youtube live facebook live. or rtmp live.

I just let DJI Pocket 3 do local rtmp streaming to "rtmp to hdmi adapter"

rtmp to hdmi adapter will turn rtmp into hdmi.

dji pocket 3. streaming to adapter. -> rtmp to hdmi adapter -> hdmi -> tv / atem mini

How to connect rtmp to hdmi adapter?

you need prepare a professional wifi router. and router ip address is 192.168.1.1

Router default ip is 192.168.1.1. it is very very important!!!

rtmp to hdmi adapter ip is 192.168.1.217 (it is fixed)

dji pocket 3 , RTMP to hdmi adpater and router are in the same intranet.

go to app "dji" and do local rtmp streaming

wifi : your home professional router

rtmp streaming: rtmp://192.168.1.217/live/test1

and then, the local rtmp streaming will become hdmi output.

搞定iPad投影Netflix到電視或電腦擷取產生黑屏糾結已久的疑問

關於擷取Netflix 黑畫面問題，我針對iOS撥出來的Netflix 由電視顯示或電腦擷取卡進行擷取，下了很大功夫研究大概會有兩件事情糾結在一起，就會產生認知的誤會結論會讓你嚇一跳！！如果你採用 1080P的擷取卡在電腦擷取, iPad是不會丟HDCP的影像出來，你的擷取卡不需要破解HDCP,一樣抓的到.....但是，有很多配件組合，產生抓不到的都市傳說.... 抓不到 iOS的Netflix主要有兩大原因 原因1. 轉HDMI轉換器問題 Netflix針對airplay 進行封鎖，但是沒有對USB-C hub DP ALT MODE封鎖呈現結果:電視只能顯示ios桌面等等，開啟netflix會黑屏幕市面上有許多在iOS上轉HDMI的轉換器，他們採用的技術是airplay串流，大概台幣幾百元就可以買到 Netflix有說過，會針對airplay技術進行阻擋～～會產生黑屏

如果你買的hdmi輸出轉換器插入ipad,需要按什麼信任／不信任或要進行投影動作才有HDMI輸出，這種hdmi輸出轉接器，一定是用airplay的技術，當然就無法使用啦信任／不信任的提示符號

有投影的動作

一般的USB-C hub 一插入就直接HDMI輸出，這一種就能用。如果不想糾結於ios轉hdmi轉換器，就去買apple原廠的lighting to av轉換器或apple原廠的usb-c hub 一定能用 原因2. HDCP問題

關於HDCP問題，電視使用者不會發生。只會發生電腦端擷取 iOS會針對連接4k擷取卡，會做HDCP保護。連接 1080P擷取卡就不會加HDCP保護有興趣朋友可以拿早期沒有破解hdcp的1080p擷取卡，去擷取ipad影像然後播放NETFLIX, 是可以成功擷取喔上述兩點，就會發生很多有趣的討論比如： 問題1：為何我有擷取到ipad桌面畫面，但是netflix卻是黑螢幕？ ANS: 問題出自於原因1。買到非原廠的ios轉HDMI轉換器。可以成功顯示ipad影像，但netfilx知道你是用airplay的技術，就變成黑屏幕啦 問題2: 為何我連ipad的桌面都抓不到 ANS: 用到了4k擷取卡。問題出自於原因2。 iOS直接丟一個HDCP的hdmi出來 問題3: 有抓到ipad的畫面、但是沒有抓到netflix 聲音 ANS. 出題出自於原因1。買到非原廠的ios轉HDMI轉換器 傻人有傻福: 我用apple原廠hdmi傳輸線，然後用了2016年買的1080p擷取卡，都能正常擷取阿～～ ANS: 原廠hdmi傳輸線，不會擋netflix. 然後又用到1080p擷取卡，ios不會針對1080p 的擷取卡進行 hdmi的加密.... 所以，當然就能成功擷取
