想请问怎么在d1开发板上通过摄像头实时输出图像到显示器上

小白想知道怎么在d1开发板上通过摄像头实时输出图像到显示器上。官方的手册给了HDMI的输出，但是只能时单个图片的输出，我想知道怎么实时输出图像

简单点，这样试一试，打开 /dev/video0读数据，把读到的数据写到 /dev/fb0。

没有video

你是想用显示屏实时显示摄像头信号吗？

可以通过V4L2获取摄像头数据并显示,可连接UVC/CSI/DVP摄像头等等。一切正常的话，会出现/dev/videoX节点，没有的话就要先解决这个问题了，一般是配置问题，比如UVC设备的话，看一下配置UVC Host 功能有无打开。
/dev/videoX节点是一切功能的基础，先把它搞定，显示的话，可以按照@whycan 晕哥的做法直接投到fb0上看效果（不过fb0只能接受RGB格式，UVC出来的数据要首先做一下格式转换）。
Tina是支持gstrmear框架的，并且适配了各类videosink设备，如果有gstremer加持，直接敲命令
gst-launch-1.0 v4l2src ! videoconvert ! ximagesink
gst-launch-1.0 v4l2src ! videoconvert ! xvimagesink
gst-launch-1.0 v4l2src ! videoconvert ! glimagesink
gst-launch-1.0 v4l2src ! videoconvert ! waylandsink
即可。
当然gst也需要配置一下，默认是没有安装的。

@caozilong 看了你说的，我可能是没查插摄像头才没video，

建议先用电脑测试。

花了半小时终于把支持uvc摄像头的 Linux配置文件整出来了：
