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。

@whycan
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。 -
@whycan 嗯

@caozilong 看了你说的,我可能是没查插摄像头才没video,

花了半小时终于把支持uvc摄像头的 Linux配置文件整出来了:
