Re: Running gst-launch-1.0 from serial console

[Michael Gruner <michael.gruner@xxxxxxxxxxxx>]

You may try to set the display. Something like 

DISPLAY=:0 gst-launch-1.0 -v v4l2src device=/dev/video0  !

'video/x-raw,framerate=(fraction)50/1,format=RGB' ! videoconvert !
xvimagesink

The :0 part may vary, but that’s typically the default value. Of course you can export it to make it last for the entire session.

Hello,

We need to start gstreamer from serial console , and see the video on
the display output (regular hdmi interface).

But trying:
gst-launch-1.0 -v v4l2src device=/dev/video0  !
'video/x-raw,framerate=(fraction)50/1,format=RGB' ! videoconvert !
xvimagesink

results in: "could not open display".

The same command works very well when we run it from the GUI by
opening a terminal.

How should we run gstreamer to make it work ?

Thank you,
ranran
