Jetson Jetpack 5.0 R35 Camera encode using v4l2 and Multimedia API issue

[2532098972]

My device information is as follows：
Model: Jetson AGX Orin
L4T:35.1.0
Jetpack: 5.0.2 GA
ubuntu 20.04
aarch64

i’m working on a special application on Jetson AGX orin which have the following data flow :

[camera]-----UYVY------>[VIC]----YUV420----->[NVENC]----H264---->[file]
I have referred to the following link：

1、https://docs.nvidia.com/jetson/l4t-multimedia/l4t_mm_01_video_encode.html

2、

3、https://forums.developer.nvidia.com/t/encode-frames-using-nvenc-v4l2/183424/12

And I have modified some code so that it can be compiled and passed on my machine

But no files were generated, and coredump occurred during “qBuffer”，
This is my code：
camera_v4l2_cuda.h (3.3 KB)
camera_v4l2_cuda.cpp (32.8 KB)

Can someone help me solve this problem? It has been bothering me for a long time

I will re upload the code I am currently using, removing the debugging information
camera_v4l2_cuda.cpp (30.5 KB)
camera_v4l2_cuda.h (3.3 KB)
