I understand that the Orin Nano doesn’t have hardware encoders, so the nvvideo4linux2 plugin doesn’t have nvv4l2h265enc. But it looks like the same nvidia-l4t-gstreamer package is installed when I flash an Orin NX 16GB, so I can’t use the hardware encoder in my pipelines even though the SoC has it.
Is there a different package that has the accelerated gstreamer elements for Orin NX?
Hi,
Do you use Jetpack 5.1.3? If you flash the system and install SDK Components through SDKManager, the hardware encoders should be present.
I need to flash using L4T for custom kernel, device trees, and pinmuxing because I’m using a custom carrier. Is it possible to get the stuff installed without flashing?
Hi,
Do you customize the kernel based on Jetpack 5.1.3? For using custom board, you can flash the board through initrd command, and the plugins shall be present after booting.
I used L4T 35.5.0, and I followed the instructions from this page: Quick Start — Jetson Linux Developer Guide documentation
First I unpacked the BSP and sample sample rootfs and updated the sample rootfs with Nvidia binaries.
tar xf ${L4T_RELEASE_PACKAGE}
sudo tar xpf ${SAMPLE_FS_PACKAGE} -C Linux_for_Tegra/rootfs/
cd Linux_for_Tegra/
sudo ./apply_binaries.sh
sudo ./tools/l4t_flash_prerequisites.sh
Then I unpacked the kernel, made my changes, compiled, and installed the products into the kernel and bootloader BSP directories.
Finally, I flashed the board:
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit internal
The nvvideo4linux2 plugin is installed and I can use nvarguscamerasrc and nvvidconv, but nvv4l2h264enc is not there, nor any of the other hardware video encoders.
Here is the list of Nvidia packages installed:

Hi,
Please clean gstreamer cache and check again:
$ rm .cache/gstreamer-1.0/registry.aarch64.bin
If the plugins are still not present, please run the commands and share the prints for reference:
$ sudo i2cdump -y 0 0x50
$ sudo i2cdump -y 0 0x57
Clearing the gstreamer cache fixed it and the elements now appear. Thanks!
