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

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有mac 版本 和windows 版本


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:

 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, 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


DV 攝影相機在WINDOWS MAC 採用OBS 做facebook youtube 直播

現在直播越來越普及,一般人可以用使手機內建的鏡頭做直播

但是手機的鏡頭畢竟是有極限的

比如,

無法拉近做特寫

沒有防手振

影像色彩沒有專業的 DV 攝影機專業


若您對於上述幾點無法接受,

想要做更專業一點的直播,可以利用DV當作是直播的來源,在電腦WINDOWS MAC 做直播



一般在電腦做直播採用的軟體是OBS

 可以在下面下載



使用的系統示意圖大致如下


DV的HDMI 連接USB HDMI 擷取器,大致示意圖如下:

"UVC grabber card"  means " usb webcam like" 


Once  USB webcam ( logitech c310 c270 c525 c920, Microsoft) can work on your PI,


FEBON series UVC grabber card will also work on Raspberry Pi.



You DO NOT install or modified the grabber driver.

It will save you a lot of  precious  time  and UVC driver is the best stability

USB3.0 uvc hdmi grabber card is compatilbe for USB2.0 mode of Raspberry pi 2

USB3.0 UVC HDMI grabber card can output 1920x1080p  30fpsuvc mjpg to Raspberry pi 2

Due to the small cpu power, the video frame of 1080p uvc is not good

it will have good frame rate when uvc output is 720p or 640x480
