FEBON UVC capture card can support web live video stream

UVC camera is usb Microsoft webcam , logitech webcam.....

Sometimes, uvc camera is not professional.

if we need  optical zoom in / out,  usb uvc webcam can not do it.


UVC grabber card can let  professional camera ( for example DV, camcorder, GOPRO , .....)

be as a webcam source.

USB webcam  →  UVC  :  USB webcam  ( logitech c310 c910...)

CVBS (composite ) source  →   become uvc   :  UVC CVBS grabber card

HDMI  source → become uvc :   UVC HDMI grabber card

SDI   source  → become uvc :  UVC SDI grabber card

FEBON UVC capture card can support the web video live stream as below

I try my best to test it for these web stream on the YouTube

720P FEBON168 USB HDMI影像擷取卡 DV 單眼相機 攝影機 用在網路直播 網路廣播 ( LIVEhouse.in / GOOGLE hangouts / USTREAM) 和skype 視訊會議

新版的 720p  FEBON168 USB HDMI影像擷取卡，增加內建scale down 功能


輸出是單一的 1280x 720p UVC  輸出


輸入的HDMI 來源又增加 1920X1080i


也就是說,

input 解析度 如下

1920x1080i  60field / 50filed

1920x1080p  60 /50fps

1280x720  60 /50fps

1366x768  60fps /50fps

720x480  30fps         

    全部都scale down  /up  自動縮放 成  1280X720P





這樣的好處是，不管HDMI 的來源是什麼解析度，

全部自動變成 1280x720


對使用者來說，自要確定 LED 上面的燈號是穩定的 （不要閃爍), 保證能用


也就是說不會發生影像截圖的問題



所有的解析度，自動縮小或放大成 1280X720P
