I tried to cpature and stream images from a CSI camera with nVidia Xavier using gstreamer. My command is :
$ gst-launch-1.0 v4l2src device=/dev/video0 do-timestamp=true ! "video/x-bayer, format=(string)bggr, width=(int)3840, height=(int)2162, framerate=(fraction)30/1" ! bayer2rgb ! videoconvert ! autovideosink -ev --gst-debug=3
but, got the following message.
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Got context from element 'autovideosink0': gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayX11\)\ gldisplayx11-0";

What's wrong?
$ gst-launch-1.0 v4l2src device=/dev/video0 do-timestamp=true ! "video/x-bayer, format=(string)bggr, width=(int)3840, height=(int)2162, framerate=(fraction)30/1" ! bayer2rgb ! videoconvert ! autovideosink -ev --gst-debug=3
I want to see Preview from camera.
