gstreamer with nvv4l2*enc working fine for a while. Today I find all nvv4l2*enc suddenly lost in gst-inspect-1.0. According this post, I try :

$ rm .cache/gstreamer-1.0/registry.aarch64.bin

nvv4l2*enc is back in gst-inspect-1.0, But still not working on gst-laucher-1.0:

gst-launch-1.0 -v videotestsrc ! autovideoconvert ! queue ! nv4l2h264enc ! filesink location=test.h265
WARNING: erroneous pipeline: no element "nv4l2h264enc"

I have try reinstall nvidia-l4t-gstreamer and any package metion on Accelerated GStreamer. And issue still remain.

Hi,
Looks like there is a typo. It should be nvv4l2h264enc instead of nv4l2h264enc. Please try

gst-launch-1.0 videotestsrc num-buffers=300 ! nvvidconv ! queue ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=a.mp4

Thanks @DaneLLL , It’s a typo problem.
But the origin problem still remain, ZED can’t encode and decode any video with h264/h265 encoding.

gst-launch-1.0 -v zedsrc svo-file-path=cc_2.42_HD720_SN21958301_16-46-59.svo ! autovideoconvert ! queue ! fpsdisplaysink video-sink=nveglglessink

I have reported to zed(#19), But this seems to be an environmental issue. In my other Jetson devices, everything works fine. Any advices?

Hi,
By default we support USB cameras through UVC driver. Looks like your camera requires additional driver. Would need to check with the vendor.
