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…
