gscam donot stream on nano,but do stream on tx2

[vxgu86]

gscam donot stream on nano,but do stream on tx2,
with nano, the nano and QGC all connect to the same hotspot,
for tx2, the QGC connect to tx2's hot spot.

that's the only difference, was this diff's problem?
here is the output of nano:
export GSCAM_CONFIG="v4l2src device=/dev/video0 ! tee name=t ! queue ! videoconvert ! omxh265enc ! video/x-h265, stream-format=byte-stream ! h265parse ! rtph265pay config-interl=1 ! udpsink host=192.168.43.184 port=6000 t. ! queue ! video/x-raw, width=1920, height=1080 ! videoconvert"
