video(1) supports reading frames from a webcam via mmap(). To inform the
V4L2 device about the number of desired buffers containing the frames to
be memory-mapped, a VIDIOC_REQBUFS ioctl call is used.
At the moment the v4l2_requestbuffers struct used for the VIDIOC_REQBUFS ioctl
is only partially

Hi,
I think I found a bug/inconsistency/regression in ctan(3) introduced
somewhere after 6.1 release. Originally observed in math/R
(https://marc.info/?l=openbsd-ports=150728711530471=2) the behavior can be
reproduced with following C program:

Hi,
in a previous commit
(http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/sys/videoio.h?rev=1.12=text/x-cvsweb-markup)
we updated our V4L2 API. However, one file (v4l2-common.h) could not be
inlined as it was only GPL2 licensed.
After discussion with the authors they agreed to dual license (GPL

Hi,
the "Lenovo N5321gw" is working for me with umb(4)
(https://marc.info/?l=openbsd-misc=147992993614369=2). So mention it
as a supported device in umb.4?
(Lenovo seems to call it Ericsson N5321gw on its support sites, so I'll
use this wording.)
OK?

Hi,
I would like to update our V4L2 (Video for Linux Two) API.
The plan is to sync sys/videoio.h with a recent version of
linux/videodev2.h (which has a BSD license statement in it) from the
Linux kernel sources. However, videodev2.h now includes two additional
headers:
1) linux/v4l2-common.h:
I would like to add V4L2_FMT_FLAG_EMULATED to sys/videoio.h as libv4l
