如何讓外接攝影機連接手機做行動直播

智慧手機有分成安卓手機和iOS手機
兩種手機都可以連外接直播擷取卡讓攝影機進行直播

安卓直播: app camaerafi live
 
iOS直播: app  medialink live
 使用擷取卡: FEBON iCapture hdmi擷取卡

https://febon.blogspot.com/2018/01/hdmi-capture-card-for-ios-iphone-ipad.html

比如你可以連接GoPro hero 7 , SONY DV等等

這兩種系統又以iPhone直播專用擷取卡的效能最好
所謂的效能指的是下面4件事情

1.直播流暢度:有沒有到每秒30fps
安卓直播會頓頓的

2.直播的bit rate 碼流可否可以調整
很可惜的， 安卓app camerafi live 的bit rate不太高，
直播過程中很容易看到馬賽克

iOS app medialink live的 bit rate可調整 10000~10000kbps

關於剛剛講的那兩點，可以看實際比較的模擬直播畫面比較
眼見為憑

You can use "FEBON uvc webcam to hdmi adapter"

USB UVC webcam camera convert to HDMI and display on TV

   This box  can let uvc usb webcam become hdmi output

"UVC webcam to hdmi" have many detail technical problem to be solve

1. UVC Webcam video stream

   UVC webcam have  YUV  and MJPG  stream

   YUV means no compression . MJPG menas compression stream.

   YUV  video frame rate will be slower than MJPG video frame rate.

   Each YUV and each MJPG also have difference resolution.


   if you catch 640X 480 resolution, the resolution is bad.


   The best uvc stream that be caught  is  MJPG  1280X720.

    The reason is as below

     reason 1: the frame rate can be 30fps

     reason 2 : the video resolution is HD. video performance is better.

          if you caugh 1920x1080 uvc, the frame rate will be reduce.

2. HDMI output is  1920X1080P

    After getting the uvc stream,  it will be convert to 1920x1080p hdmi output.

        We can not fixed the uvc resoution and uvc format and uvc frame rate.

   so, it must have the ability that can let all of kind of uvc resolution  become  1920x1080p  full HD hdmi output.


   

如何讓GoPro HERO 7 Black 在iPhone iPad實況直播

GoPro hero 7 black內建的app "gopro" 可以讓gopro hero 7 black直接用wifi 連接
透過iPad iPhone做實況直播

除了無線的連線外，還可以使用有線HDMI方式連接:







1.無線連線直播

目前只能做臉書的個人直播，無法做臉書的粉絲團直播

 沒有youtube twitch 直播，必須要透過手動貼上rtmp串流碼才能進行直播

同時使用四支攝影機(GoPro SONY攝影機等)在iPad上做臉書直播

想法大概是這樣：

攝影機:
1.GoPro ( hero 7 hero 6 hero 5 hero 4都可以）
2.SONY action cam 運動攝影機
3. SONY  camcorder  攝影機 pj675
4. iPhone的hdmi輸出

使用SONY AS300運動攝影機做長時間戶外行動實況直播

戶外走動式的實況直播和室內直播不一樣

長時間的戶外直播是走動跑步，需要的設備也需要小一點，
不然扛一台電腦直播，總是很奇怪吧？

剛剛提到了三個重點

1.長時間直播
可用長時間使用的行動電源，要有快充的行動電源
 
2.走動跑步:
   這時候所選擇的攝影機就要有很好的防手震
   目前的運動攝影機如GoPro hero 雖然說也有防手震，但是他是電子防手震
電子防手震的效果沒有光學防手震的好

選來選去，就找到SONY  AS300　
這款是光學防手震，效果比GoPro hero5好的太多了

防手震好的攝影機不僅影像比較不會讓你頭暈，
 直播的上傳Bit rate會更穩定,不會忽高忽低，
間接會影響到直播的流暢度...

如何收納及使用攝影機(DSLR 運動攝影機 DV)做行動SNG實況直播

分享一下我的行動直播的心得
如何使用外接攝影機DSLR做行動實況直播

行動直播跟定點直播有一些差異
1.網路連線穩定及速度的差異
->定點直播可以使用固網，行動直播只能用4G

若你的錢夠多話，可以考慮4G聚合路由器

2.設備收納的差異
->定點直播不在意直播設備的體積重量，行動直播在意收納

行動直播需要輕巧好收納

3.設備是否可以邊使用邊充電(電源問題)
->定點直播使用電源供應器，行動直播要考慮是否可以邊使用邊充電

行動直播需要考慮到是不是可以連續使用很久


4.是否容易登錄直播平台
-> 定點直播很容易copy paste金鑰，行動直播需要很容易登入直播

行動直播需要考慮到好不好登錄直播平台進行直播
如果還要copy paste金鑰，那就很麻煩了

5.是否可以調整解析度和bit rate
->定點直播的OBS可以調整,行動直播也是需要考慮這點

一般行動直播都沒有考慮到bit rare

External video device communicate with iOS app over USB lightning ( peertalk of USBmuxd)

How to let external device communicate with iOS?

eg:  WIFI router, wifi ip camera, lightning flash card and etc.



There are 4 major format that can communicate with iOS

Information (云峰小罗): https://www.jianshu.com/p/08da95add4da

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

How to let iPad iPhone camera be support clean video ( clean hdmi clean camera ) for OBS Studio

USB  keyboard-> ok

USB Mouse -> NG

USB webcam -> NG

可以讓你的GoPro hero 5 hero 6 等運動攝影機當成直播的視訊來源，
在臉書 Youtube Twitch等實況直播平台進行直播

這裡討論兩種方法透過手機直播


1.  WIFI 無線連線方式實況直播

這種方法很方便
沒有很多線材纏來纏去

但是，缺點可是蠻多的
1.1 若要邊使用邊充電，仍要纏繞一些線材
1.2 實況直播的影像品質只有480p (640x480),   低的bit rate

 2. 使用有線的HDMI連線，實況直播

透過有線HDMI連線方式，連接相對應的擷取卡

這樣的直播缺點是需要纏繞線材

確有許多好處
1.實況直播穩定度提高，少了無線干擾問題
2.實況解析度最高可以到 1920x1080p 30fps 且bit rate比較高
