UVC_SET_CUR Update the value of the control.Īpplications must set the 'size' field to the correct length for theĬontrol. UVC_GET_INFO Query the control information bitmap, which indicates whether

UVC_GET_LEN Query the size of the control in bytes. the step size of theĪllowed control values. UVC_GET_RES Query the resolution of the control, i.e. UVC_GET_DEF Obtain the default value of the control. UVC_GET_MAX Obtain the maximum value of the control. UVC_GET_MIN Obtain the minimum value of the control. These requests are: UVC_GET_CUR Obtain the current value of the control. There are a number of different queries available that closelyĬorrespond to the low-level control requests described in the UVC This ioctl queries a UVC XU control identified by its extension unit ID For the time being they are still supported butĪpplication developers are encouraged to use UVCIOC_CTRL_QUERY instead.įor details on the UVCIOC_CTRL_QUERY ioctl please refer to the section titled

UVCIOC_CTRL_SET ioctls have become obsolete since their functionality is a With the addition of the UVCIOC_CTRL_QUERY ioctl the UVCIOC_CTRL_GET and Supported) of the resulting byte indicate which requests are valid. UVC_GET_CUR or UVC_SET_CUR are valid requests for a given control, a UVC_GET_LEN requests in order to be able to allocate a sufficiently large bufferĪnd set the buffer size to the correct value. Unless the control size is already known it is necessary to first make a UVC descriptor or, if available, using the media controller API to enumerate a Hardcoded in the application or queried using other ways such as by parsing the In order to make such a request the UVC unit ID of the control's extension unitĪnd the control selector need to be known.

Purposes, firmware upload, or accessing binary controls, a second mechanism toĪccess XU controls is provided in the form of a driver-specific ioctl, namelyĪ call to this ioctl allows applications to send queries to the UVC driver thatĭirectly map to the low-level UVC control requests. This is no longer necessary as newer uvcvideo versions query the informationįor details on the UVCIOC_CTRL_MAP ioctl please refer to the section titledįor applications that need to access XU controls directly, e.g. Previous driver versions (before 0.2.0) required another ioctl to be usedīeforehand (UVCIOC_CTRL_ADD) to pass XU control information to the UVC driver. The ioctl used to create these control mappings is called UVCIOC_CTRL_MAP. Triggers a read or write of the associated XU control. However, reading or writing of such a V4L2 controls the stock controls, such asīrightness, contrast, etc.). Such controls appear andįunction exactly like normal V4L2 controls (i.e. Ranges thereof to be mapped to new V4L2 controls. These allow for individual XU controls or byte With my D7000 attached to the PC via USB I can see the images on the big screen as I shoot.The UVC driver provides an API for user space applications to define so-calledĬontrol mappings at runtime. This is fantastic! I have it on my HTPC attached to a 50" plasma TV in my recroom / photo studio. and particularly because its free! Linus Ku This is truly an amazing piece of software.

#Linux uvc camera control software#

Just want to say that I LOVE this software !! I use an older Nikon D200 with a grip and while I can't tether into Lightroom, I can tether into Digicam control and I can turn it on and off, switch lenses and just keep going on my shoots and it never fails me smile emoticon,thank you so much, keep up the great work.

#Linux uvc camera control pro#

Thank you so much for being available to a fresh photography pro like me!! Well done! Tom Elliott Simple interface, great camera control, satisfied clients at my end.

DennisonĭigiCamControl saved my bacon!!! Thank you for being there when I needed you. I especially prefer your much larger live view window & histogram display.! Patrick M.

#Linux uvc camera control upgrade#

Thank you for the upgrade to Nikon's OEM Camera Control utility. Thank you ! Rob ErtĮxcellent, for the basic tethering I want to do this seems to work just fine, A great alternative and cash saver. This software is great, amazing that its free, deserves a Paypal donation for sure. Great program, used for focus stacking on the Nikon d90 with awesome results! Ben Price I love it, simple but better then some other.
