I don’t get why you’re using a nano here for streaming to server, but:
- AGX Xavier may have at least 100 ms glass to glass latency (using TX2 devkit’s OV5693 sensor on R34.5 and gstreamer pipeline to xvimagesink).
- you may use a USB link from Xavier to Nano micro-usb port that should bring both a device storage and an IP bridge so that you’ll get an IP link (use ifconfig to get your IP address over this link from AGX and nano). Alternatively you may try nano as host and AGX as device.
- So you may use RTP over this IP link and use RAW over RTP such as here.
- This would add about 100 ms additional latency, for a 640x480@30 fps resolution. For higher resolutions x framerates, you may have to adjust kernel socket max buffer size, mtu and more, but never tried over usb.
- For sending from nano over GSM, you may have to consider a compressed format depending on what you can afford.
