USB3.0 FEBON180 免驅HDMI 擷取器 USB3.0 FEBON169 免驅HDMI擷取器

 

FEBON180的聲音有做自動取樣率處理,
建議採用此擷取器設定成直播的聲音來源


FEBON169的聲音擷取沒有做自動取樣率處理
不建議用此台擷取器當作是聲音的來源
若一定要用這台的聲音來源,請到windows 音效管理員調整適當的聲音取樣率
通常是 48KHZ

自己準備綠背景和攝影機

不建議用CANON 單眼 : 因為沒有聲音,只有影像

這類相機不支持  Clean HDMI (hdmi影像會顯示相機的資訊如對焦的符號 電池容量等)

canon 單眼相機會出現相機的資訊



DV 方面,不建議用 SONY  HDR-CX405, 這款的hdmi輸出只有影像沒有聲音



下圖是採用 SONY HDR-PJ675  亦可採用 SONY HDR-CX450

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



USB3.0 FEBON180 UVC HDMI capture card

AUDIO auto detect sampling rate 

 It can automatically detect the input audio formats and swift it to 48KHz PCM audio.





Follow standard UVC MJPG/YUV  for USB3.0  and USB2.0 


  USB3.0 high speed mode is up to 1920x1080p 60fps YUV /mjpg
     
    conditions :
                WIN8.1 /WIN10/MAC OSX /x86 ubuntu + intel i5 up+ USB3.0 XHCI
  

USB2.0 normal mode (Android application) is up to 1920x1080p 30fps mjpg

     conditions:  it can compatible all of PC. 

 
 
 if your PC is not follow this conditions, it can not work on USB3.0 mode
you need add the usb2.0 line to become usb2.0 mode (as below picture)
