Jetpack 6.2 RTSP Stream Enable Nvidia Decoder

[Alpha.Chen]

Hi,
I try theese pipeline work is ok.

gst_str = ('rtspsrc location={} latency={} ! '
                   'rtph264depay ! h264parse ! avdec_h264 ! '
                   'videoconvert ! appsink drop=true').format(uri, latency)

How Can I use Gstreamer with opencv enable nvv4l2decoder?
Thanks!

Hi,
Please refer to the samples and give it a try:
Doesn't work nvv4l2decoder for decoding RTSP in gstreamer + opencv - #3 by DaneLLL
Displaying to the screen with OpenCV and GStreamer - #9 by DaneLLL

Theese look likes work ,but performance not very better.

if 'nvv4l2decoder'in gst_elements:
        gst_str = ("rtspsrc location={} latency={} ! rtph264depay !"
                   " h264parse ! nvv4l2decoder ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert !"
                   " video/x-raw,format=BGR ! appsink drop=true").format(uri, latency)

Hi,
Please try

And also run $ sudo jetson_clocks
