silverlight4提供了摄像头机麦克风访问的API，尝试了一下，还不错。现在将简单的程序记录一下
sl前台呢，有两个控件，一个是用于显示摄像头捕捉到的内容，另一个是个按钮用来启动摄像头。
<
Rectangle
Height
="169"
HorizontalAlignment
="Left"
Margin
="37,21,0"
Name
="rectangle1"
stroke
="Black"
strokeThickness
="1"
VerticalAlignment
="Top"
Width
="236"
/>
< Button Content ="Button" Height ="23" HorizontalAlignment ="Left" Margin ="120,196,0" Name ="button1" VerticalAlignment ="Top" Width ="75" Click ="button1_Click" />
< Button Content ="Button" Height ="23" HorizontalAlignment ="Left" Margin ="120,196,0" Name ="button1" VerticalAlignment ="Top" Width ="75" Click ="button1_Click" />
CaptureSource source
=
new
CaptureSource();
if (source != null )
{
source.Stop();
source.VideoCaptureDevice = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice();
VideoBrush vidBrush = new VideoBrush();
vidBrush.SetSource(source);
this .rectangle1.Fill = vidBrush;
if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.RequestDeviceAccess())
{
source.Start();
}
}
使用模拟摄像头做的效果
if (source != null )
{
source.Stop();
source.VideoCaptureDevice = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice();
VideoBrush vidBrush = new VideoBrush();
vidBrush.SetSource(source);
this .rectangle1.Fill = vidBrush;
if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.RequestDeviceAccess())
{
source.Start();
}
}
使用模拟摄像头做的效果
还可以截图等等。
非常简单，哈哈。
下一次将会对这个视频进行传输，完成视频对话的过程。
