Hi,

We have Installed Ubuntu and Gstreamer at AWS
and when running this command
gst-launch-1.0 v4l2src ! videoconvert ! ximagesink

We are getting this error
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstXImageSink:ximagesink0: Could

Additional debug info:
