Getting started with video test pattern

Hello, I’m new to openhd and have been trying to get my airpi to send the default video test pattern found in settings-1 to my groundpi.

Both pi are 3b+ and are both running openhd version 2.0.0rc17. My ground pi has one Alfa AWUS036NHA wifi cards while my airpi has one of them. I’ve followed the wiki and set secondaryCamera=USB and IsCamera1Enabled=1. I also uncommented the USBCamera=“gst-launch-1.0 videotestsrc…” on the airpi in order to stream the test video.

When I boot up both pi, the ground pi recognizes the air pi and connects to it, although no video is streamed. The airpi is also hooked up to a monitor and when booted it displays the following messages:

Setting pipeline to PLAYING …
can’t get device qualifier: Resource temporarily unavailable
CRITICAL: gst_video_frame_map_id: assertion ‘GST_IS_BUFFER (buffer)’ failed
GStreamer-CRITICAL: gst_pad_push: assertion ‘GST_IS_BUFFER (buffer)’ failed
streaming stopped, reason error (-5)
Setting pipeline to PAUSED …
Setting pipeline to READY …
Setting pipeline to NULL …
Freeing pipeline …

Can anyone lead me in the right direction for anything I might not have configured correctly?
Thanks!
