Thanks Joseph, that helped me locate the problem:
Run till exit from #0 0x00000008036433e0 in ioctl () from /lib/libc.so.7
0x0000000000416cc8 in xioctl (vid_source=0x80c014300, request=1080579584,
arg=0x80c014308) at video_v4l2.c:177
177 ret = ioctl(vid_source->fd_device, request, arg);
Current language: auto; currently minimal
(gdb) bt
#0 0x0000000000416cc8 in xioctl (vid_source=0x80c014300, request=1080579584,
arg=0x80c014308) at video_v4l2.c:177
#1 0x0000000000417928 in v4l2_get_capability (vid_source=0x80c014300) at
video_v4l2.c:185
#2 0x00000000004157de in v4l2_device_init (cnt=0x80bc4b000,
viddev=0x80c00f0c0, width=960, height=720, input=-1, norm=0, freq=0,
tuner_number=0)
at video_v4l2.c:790
#3 0x0000000000415527 in v4l2_start (cnt=0x80bc4b000) at video_v4l2.c:1226
#4 0x000000000041ad2e in vid_start (cnt=0x80bc4b000) at video_common.c:657
#5 0x00000000004088a0 in motion_init (cnt=0x80bc4b000) at motion.c:879
#6 0x000000000040836d in motion_loop (arg=0x80bc4b000) at motion.c:2476
#7 0x00000008032de755 in pthread_create () from /lib/libthr.so.3
#8 0x0000000000000000 in ?? ()
I changed line 168 from:
#ifdef __OpenBSD__
to:
#if defined (__OpenBSD__) || defined (__FreeBSD__)
and that fixed the problem. Can somebody commit this, or should I create an
issue on GitHub?
Kind regards,
Ben

Great! If you have the time to create a merge request in GitHub with that
change in it that would be really appreciated!
Thanks
