Forwarding to Jetson Nano

[elifozisik]

Hi,

I use 2 Raspberry Pi 3 and one jetson nano. I connect ground station Raspberry Pi to jetson nano via ethernet. And I want to receive the drone video from jetson nano? How can i forward the video to Jetson Nano? Have you any idea?

Thanks.

Add to /etc/wifibroadcast.cfg on GS:

[gs_video]
peer = 'connect://X.X.X.X:5600'

where X.X.X.X is ip-address of the Jetson Nano.
Then run gstreamer pipeline which will listen on udp 5600 and decode rtp-h264 stream on jetson nano.

I try to this command in terminal but i got an error Spinning. Please run 'gdb gst-launch-1.0 21982' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
Command

gst-launch-1.0 udpsrc port=5600 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264' \
               ! rtph264depay ! avdec_h264 ! clockoverlay valignment=bottom ! autovideosink fps-update-interval=1000 sync=false

Have you restart service after config file modify?

[elifozisik]

yes

Try this:

gst-launch-1.0 udpsrc do-timestamp=true port=5600 caps='application/x-rtp' ! rtph264depay ! h264parse disable-passthrough=true ! avdec_h264 ! xvimagesink sync=false

but it is not accelerated and may be slow on jetson. You need to found pipeline which use OMX if this example succeeds

I tried that command but didn't happen

run wfb-cli gs on the GS

check with tcpdump that jetson receive video stream from GS. According to wfb-cli GS works correctly

Isn’t this since both services need to be started on gs, as described in another discussion? (Not sure which discussion)
