- Power supply considerations for Jetson Nano Developer Kit
No. Secureboot is only supported on production module(Jetson Nano with emmc).
Please see this thread - Debug tips when you hit any issue (fail to boot/ keep reboot ...etc)
Run below commands:
$ sdkmanager --archivedversions
Q: When I try to Install SDK components, the SDK Manager says “Could not detect Nvidia Jeson device connected to USB”. Does anyone also hit the issue?
You can switch to use eth0 ip address to install SDK components:
Run the "sdkmanager" -> choose your "target device" and "install version" -> unselect Flash OS and select install "SDK components" -> Press enter to enter your eth0 ip address(of Jetson Nano), username and password to start install sdk components.
We have enabled hardware decoding. Please check development guide. Enabling hardware encoding is underway.

You can get supported modes via v4l2-ctl:
$ sudo apt install v4l-utils $ v4l2-ctl -d /dev/video1 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUYV 4:2:2 Size: Discrete 640x480 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.042s (24.000 fps) Interval: Discrete 0.050s (20.000 fps) Interval: Discrete 0.067s (15.000 fps) Interval: Discrete 0.100s (10.000 fps) Interval: Discrete 0.133s (7.500 fps) Interval: Discrete 0.200s (5.000 fps)
And launch one mode(Ex: 640x480p30) in gstreamer command:
$ gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! nvoverlaysink
From r32.4.3(Jetpack4.4), we have new plugin nvv4l2camerasrc, you can leverage it to achieve zero copy:
$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video1 ! video/x-raw(memory:NVMM),format=UYVY,width=640,height=480,framerate=30/1 ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12' ! nvoverlaysink
By default it supports UYVY. If your source supports other format such as YUYV(YUY2) or YVYU. You can download the source code, add the format and rebuild/replace the plugin. The source code is in

There is an ease-to-use gstreamer sample to run RTSP server. The steps:
gst-rtsp-server/test-launch.c at 1.14.5 · GStreamer/gst-rtsp-server · GitHub
Build the sample
sudo apt-get install libgstrtspserver-1.0 libgstreamer1.0-dev gcc test-launch.c -o test-launch $(pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0)
- Launch the server
$ ./test-launch "videotestsrc is-live=1 ! nvvidconv ! nvv4l2h264enc ! h264parse ! rtph264pay name=pay0 pt=96"
At client side, if the device is a PC with Windows OS, you can open network stream rtsp://<SERVER_IP_ADDRESS>:8554/test via VLC. If it is a Jetson device, you can run the command:
$ gst-launch-1.0 uridecodebin uri=rtsp://<SERVER_IP_ADDRESS>:8554/test ! nvoverlaysink
