, 15:08, 29 March 2023→使用gstreamer预览UYVY格式图像
<code>gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)$WIDTH, height=(int)$HEIGHT,framerate=(fraction)$FPS/1" ! v4l2convert ! "video/x-raw,format=(string)NV12" ! autovideosink sync=false -v</code>
<code>gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)$WIDTH, height=(int)$HEIGHT,framerate=(fraction)$FPS/1" ! v4l2convert ! "video/x-raw,format=(string)NV12" ! autovideosink sync=false -v</code>
或者简单的
<code>gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! autovideosink</code>
