Gstreamer RTSP Stream with Jetson Orin NX and USB camera: Can't find hardware encoding

[arkbbusiness]

I am a beginner and wanted to dabble with IP/USB cameras using Jeton hardware (Orin NX). My camera is capable of outputting 4k/30fps and seems to be decent.

I was able to setup an rtsp stream with my Orin NX connected to the camera USB and got it to run with gst through this command :

test-launch "( \ v4l2src device=/dev/video0 ! \ video/x-h264,width=1920,height=1080,framerate=30/1 ! \ h264parse ! \ rtph264pay config-interval=1 name=pay0 pt=96 )"

but when I tried using hardware encoding/decoding here where I noticed that I’m missing nvv4l2h264enc.

gst-inspect-1.0 | grep h264
libav: avdec_h264: libav H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 decoder libav: avenc_h264_omx: libav OpenMAX IL H.264 video encoder encoder openh264: openh264dec: OpenH264 video decoder openh264: openh264enc: OpenH264 video encoder rtp: rtph264depay: RTP H264 depayloader rtp: rtph264pay: RTP H264 payloader typefindfunctions: video/x-h264: h264, x264, 264 uvch264: uvch264deviceprovider (GstDeviceProviderFactory) uvch264: uvch264mjpgdemux: UVC H264 MJPG Demuxer uvch264: uvch264src: UVC H264 Source videoparsersbad: h264parse: H.264 parser

I updated l4t multimedia package. reinstalled gstreamer multiple times but still nothing to be found, so can anyone please help me enable hardware encoding?

Also I should mention that my gst version is : GStreamer 1.20.3 and I’m running Jetpack 6 (L4T R36.4)

thanks in advance!

Hi,
Please try the commands and see if it is present:

$ sudo apt update
$ sudo apt install nvidia-l4t-gstreamer
$ rm .cache/gstreamer-1.0/registry.aarch64.bin
$ gst-inspect-1.0 nvv4l2h264enc

If there is still no nvv4l2h264enc, please run the command $ sudo apt install nvidia-l4t-gstreamer and share the print for reference.

I tried it and still can’t find nvv4l2h264enc here’s the print:

$ sudo apt install nvidia-l4t-gstreamer

Hi,
It looks like nvidia-l4t-gstreamer is installed. Please run $ sudo i2cdump -f -y 0 0x50 and share the prints for reference.

Hi,
The module is Orin Nano 8GB per
Welcome — NVIDIA Jetson Linux Developer Guide

3767-0003 is Orin Nano 8GB. It is expected there is no hardware encoder.
