ok deraadt@ ian@
2021-02-16Also call the VIDIOC_STREAMOFF ioctl when we stop a read(2) stream. ThisMarcus Glocker
is required by the new video(4) multiopen functionality.

Reported by Laurence Tratt.

2020-08-09If a control supports auto mode and this is active, print 'auto' with -cMarcus Glocker
instead of printing the last set numeric value. Initial diff from Laurence Tratt with some enhancements added.

With best regards from clang 10.

2020-07-01Initialize v4l2_requestbuffers for better libv4l compatibilityIngo Feinerer
The VIDIOC_REQBUFS ioctl requires a v4l2_requestbuffers struct with the members count, type, and memory. In the past only count was set as the uvideo(4) kernel driver, via uvideo_reqbufs(), is ignoring both struct members type and memory (pointed out by mpi@). However, using video(1) with libv4l (LD_PRELOAD=/usr/local/lib/v4l2convert.so video) yields "mmap: Invalid argument" as libv4l inspects the type and memory struct members and fails if memory != V4L2_MEMORY_MMAP. Full initialization fixes libv4l usage which allows us to view video encodings not directly supported by video(1), e.g., MJPEG, as libv4l can convert encodings on the fly. OK mglocker@
2019-11-06Tested a Logitech Webcam C930e which has 17 frame sizes but video(1) onlyMarcus Glocker
supports 16 today. Bump the array to 32 which makes 1920x1080 work on this device as well. OK deraadt
2019-02-25Add support for yv12 encoding to video(1).Raphael Graf
Frame data is converted to yv12 if Xv(3) does not support yuy2 and uyvy. OK mpi@, landry@
2019-01-22Pledge video(1):Landry Breuil
* video -q needs 'stdio rpath wpath video' (needs O_RDWR on the device) * video -i needs 'stdio rpath' (rpath for X11 error/locale access) * other modes (ie display frames via X11, or output frames to file with -o/-O) need 'stdio rpath video' since we open output file/video device before calling pledge(2). with help from semarie@, nits from matthieu@ ok deraadt@

2018-04-09Measure statistics against UPTIME clock.cheloha
So that your statistics remain correct if the system wall clock is changed during playback. Use CLOCK_UPTIME instead of CLOCK_MONOTONIC so that statistics remain correct across suspend/resume. Testing by tobias@, sthen@, and Benjamin Baier <programmer AT netzbasis DOT de>. ok sthen@

2016-09-16Make video -i work ootb.Jeremie Courreges-Anglas
video(1) uses mmap and ioctls by default, those ioctls only work on video(4) devices. If -i is passed, use read(2) instead of the mmap(2) routines, instead of requiring the user to pass also pass the -g flag.
2016-06-06Comparing maximum frame buffer size after VIDIOC_DQBUF ioctl againstMarcus Glocker
'buf.bytesused' instead of 'buf.length' makes more sense. From Patrick Keshish
2016-06-06To match the encoding type, compare against 'pixelformat' instead ofMarcus Glocker
'description' which could contain any value. Fixes VIDIOC_ENUM_FMT ioctl for utvfu(4). Spotted by Patrick Keshish. ok mpi

confusion whether this is supposed to be a call to the .Rv macro. Found by a warning issued by the the groff_mdoc(7) macros.

spotted by sobrado@
2011-04-11* use VIDIOC_ENUM_FRAMEINTERVALS to get the supported frame intervalsJacob Meuser
and display the frame rates if at least on -v is used. * set/get the video(4) device's frame rate using VIDIOC_{S,G}_PARM. * add new option -R which dsables frame rate adjustment. only really useful for video(4) devices, to see the difference between the frame rate the device generates and what it says it's configured for ... many devices don't generate the rate they are configured if they aren't getting enough light ... * poll(2) input with INFTIM instead of 0 timeout, and handle the poll(2) call being interrupted by the frame timer. * only use usleep(3) to wait for frames if the input is a file, and in that case, sleep for a full frame interval or until interrupted by the frame timer. * update the manual to describe the new -R option, that -r now sets video(4) frame rate, and that at least one -v will display supported properties of the hardware.
