Hi DaneLLL

Thank you for your reply.
I found workaround by myself which is described in that topics on 19th Feb.

Libv4l2_nvargus.so source code

Hello, If I build again the example from: https://linuxtv.org/downloads/v4l-dvb-apis/userspace-api/v4l/v4l2grab.c.html It works only modifying the line: fd = v4l2_open(dev_name, O_RDWR | O_NONBLOCK, 0); to fd = open(dev_name, O_RDWR | O_NONBLOCK, 0); One difference with the first call is that it outputs the message “Opening in BLOCKING MODE” before the segmentation fault, so it seems the flag O_NONBLOCK has no effect. I don’t know if this can be a clue…

That is, I use open() instead of v4l2_open(), it can run fine.
But I forgot to write this workaround.

Should I use open() instead of v4l2_open()?
