I’ve settled a CSI-camera and try to use nvgstcapture-1.0 to open it. But the error shows

JPEG parameter struct mismatch: library thinks size is 728, caller expects 720

Here is libjpeg version show by apt list | grep libjpeg for your information:

Do you know How to fix this?
Here is the environment:
Environment:
Jetpack: 5.1.3
python: 3.8
Gstreamer: 1.16.3
OpenCV:4.5.4
System: Ubuntu 20.04

What’s the camera output size?

4

It’s 1280*720.

Hi,
Please try gst-launch-1.0 command to check if the issue is specific to nvgstcapture-1.0:

$ gst-launch-1.0 nvarguscamerasrc ! fakesink
8

The sigsegv happens in this case:

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Caught SIGSEGV
Spinning.  Please run 'gdb gst-launch-1.0 4298' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.

Hi,
We don’t expect the error on default Jetpack release. Please clean gstreamer cache and see if you can successfully run the command.

10

How to clean gstreamer cache? I’m a new user and not familiar with gstreamer.

11

Hi,
Please try

$ rm ~/.cache/gstreamer-1.0/registry.aarch64.bin
12

Clearing cache doesn’t help. After clearing the cache and run gst-launch-1.0 nvarguscamerasrc ! fakesink
SIGSEGV still repeats:

Hi,
Please re-flash the system to 5.1.3 through SDKManager and try again. It would be great to have a clean system and check if the issue still occurs.

14

Is is possible to re-flash system directly via ubuntu in jetson instead of SDK manager in a host computer? It’s because now I don’t have available host linux system.

16

No, you need to have a host PC with Ubuntu.
