使用OBS 讓外接的攝影機DV 做facebook直播或是Youtube直播教學

 
如何在電腦讓外接的攝影機dv做直播呢?

通常會採用一個第三方軟體OBS

OBS studio 有mac 版本 和windows 版本


除了OBS之外,也有付費的直播軟體,如wirecast  等等

但是一般普羅大眾採用OBS 已經是足夠了,

在沒有預算前提下,OBS是最佳選擇

此篇是基於OBS studio 的直播教學設定

攝影機的訊號進到電腦,然後透過OBS的處理,處理後的訊號即時丟到直播平台直播

直播平台比如是 facebook直播 Youtube直播 或是 Live house in

示意圖如下:





分成幾部分討論:

網路連線


網路連線是最根本的,
如果你的影像品質都不錯但是網路上傳很差,那麼一切就都很差了

網路是最根本!! 網路是最根本! 


通常你可以看到直播軟體OBS的右下角有一個網路速度

以下圖為例是寫 2726

 通常這個數字至少都要1000 以上才算是穩定正常的

低於1000 的話,會影響到直播的品質,甚至於斷線





我是建議使用有線網路RJ45來進行直播

mac 的用戶可以去買一條RJ45  轉 USB 的轉接器

晶片是 AX88772A

這款晶片在mac 筆電是不用驅動程式的

下面的表格,是對應需不需要驅動程式的轉接器








攝影機:

通常會採用攝影機的hdmi 輸出連接到電腦,

但並非所有的攝影機hdmi 都有都有live輸出

一些消費型的相機,並不具有live 影像輸出,這些消費型相機的hdmi 輸出是用來觀看儲存在sd卡的影像

比如:panasonic GF3 GF4 這些消費型相機就不能做直播


另外,有一些相機的hdmi輸出是有live影像,但是卻沒有聲音,如CANON 500d 600d 等等

我不建議用canon 單眼相機直播

除了沒有聲音外,他的影像輸出是1920x1080i,

不是1920x1080p的話, 影像品質大打折扣


我建議採用SONY DV  直播

影像品質好,又有防手振,對焦又快


OBS (Open Broadcaster Software) let DV Camcorder livestreaming with facebook live Youtube live

 

How to let DV camcorder live streaming on PC?

HDMI output of DV camcorder input PC.
and then use OBS to process the video  and then...... live upload into facebook / Youtube


diagram:






We can divided many things to discuss.

Internet connecting


Internet is the basic problem.
if your video performance is  better but internet is not good, the livesstreaming will be bad


internet is the basic issue!!


Usually, we can see the internet speed on the end of OBS software 

For example: 
you can see the internet upload speed is 2726 


if the number is below. 1000, the internet is bad!

it will occur the interrupt livesteaming!






W suggest that you can use the wire internet. 

For MAC use,  you can add the " RJ45 to USB adapter"



internet main chip is  AX88772A


This chip AX88772A is dirverless for MAC OSX








DV camcorder:


 We always use HDMI output of camcorder as the video source


But, Not all of camorder have live hdmi output.

Although you can see the hdmi connector on the Camcorder,  it just for play back not live video



For examle:
Panasonic GF3 GF4 .

its hdmi output just for play back only





By the way, some camera hdmi  output is just video only and no audio

For example: Canon DSLR  (500d, 450d....7d......)


I DO NOT recommend that you use Canon as the video source.

reason:
1. no audio
2. video is just 1920x1080i output.

For USB2.0 FEOBN168 UVC HDMI grabber card, it will have a little up and down.





I suggest that you can use SONY DV camcorder as video / audio source
