Stream with DirectShow (Windows) 基於DirectShow的流(Windows)

Install your peripheral drivers

You need to install your peripherals under Windows with the appropriate drivers. Nothing else is necessary.

安裝您的外圍驅動程式

你需要給Windows下的外設安裝適當的驅動程式。沒有其他必要的事情。【注：遵循UVC的裝置則無需安裝驅動】

Stream unicast/multicast with VLC in command line

% C:\Program Files\VideoLAN\VLC\vlc.exe -I rc --ttl 12 dshow:// vdev="VGA USB Camera" adev="USB Camera" size="640x480" --sout=#rtp{mux=ts,dst=239.255.42.12,port=5004}

Note: You either need to provide the full path to the vlc.exe executable or add its location to the Windows Path variable.

注意：你要麼提供vlc.exe的全路徑，要麼將其所在位置新增到windows的path環境變數中。

• -I rc is to activate the remote control interface (MS/DOS console) 啟用遠端控制介面(MS/ DOS控制檯)
• 12 is the value of the TTL (Time To Live) of your IP packets (which means that the stream will be able to cross 11 routers),
  你的IP資料包的TTL(生存時間)值(設為12，就意味著流將能夠跨越11臺路由器),
  
  
• vdev="VGA USB Camera" is the name of the video peripheral that DirectShow will use (this is only an exemple),
  DirectShow將使用的視訊外設的名稱(這只是一個例子),
  
• adev="USB Camera" is the name of the audio peripheral, 音訊外設的名稱
• size="640x480" is the resolution (you can also put the standard size like subqcif (128x96), qsif (160x120), qcif
