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.

MEVO Start直播攝影機開箱測試 |臉書1080p直播 | USB webcam模式 | NDI模式 | HDMI輸出接導播機ATEM MINI

前幾天有一個外國人問我是否MEVO Start 直播攝影機是否可以轉成hdmi 輸出
因此，我就花了一萬五千元買了一台MEVO Start 測試

MEVO Start 直播攝影機，的影像原始解析度非常高，
利用數位放大的方式，達成類似攝影機的PTZ
來控制MEVO Start是你的行動裝置iPhone iPad.

直播的主要連線如下：

1.MEVO Start內建的臉書1080p直播

2. MEVO Start變成一個USB UVC WEBCAM 連接電腦OBS直播

3. MEVO Start可無線NDI輸出，讓OBS抓到NDI訊號直播

有趣應用：
4.MEVO Start的USB WEBCAM轉成HDMI 輸出, ATEM mini導播機應用
5.MEVO Start的NDI輸出轉成HDMI

我這裡分享其他直播方式的冷知識...
採用有線usb連接及無線NDI方式直播
我個人是喜歡用有線方式，比較穩定 NDI方式也可以採用有線，但是那條USB-C 乙太網路太貴了.. 所以就用無線NDI示範

MEVO Start內建無線的臉書1080p 直播
一般的臉書直播只有720p
透過MEVO Start直播攝影機的直接臉書直播，可以達到1080p
1080p的FB直播不是這麼神秘～
MEVO 有跟臉書申請特別的api, 當然就可以1080p直播
以下是簡單的FB 1080P直播介紹

MEVO Start變成一個USB UVC WEBCAM 連接電腦OBS直播
