Hello,
The short story:
We need to start gstreamer from serial console , and see the video on the display output (regular hdmi interface).
But on running:
gst-launch-1.0 -v v4l2src device=/dev/video0 ! 'video/x-raw,framerate=(fraction)50/1,format=RGB' ! videoconvert ! xvimagesink
we get:
"could not open display".
Note: the same command works very well if executed from terminal in the screen, but doing the same from serial console fails.
How should we run gstreamer to make it work ?
Thank you,
ranran
