    1

    If ctrls->count is too high the multiplication could overflow and
    array_size would be lower than expected. Mauro and Hans Verkuil
    suggested that we cap it at 1024. That comes from the maximum
    number of controls with lots of room for expantion.

  • cc1d32723   [media] v4l: Add new alpha component control ... Browse Code »

    The V4L2_CID_ALPHA_COMPONENT control is intended for the video capture
    or memory-to-memory devices that are capable of setting up the per-pixel
    alpha component to some arbitrary value. It allows to set the alpha
    component for all pixels to an arbitrary value.

  • 74a457908   [media] videodev2.h: add V4L2_CTRL_FLAG_VOLATILE ... Browse Code »

    Add a new VOLATILE control flag that is set for volatile controls.
    That way applications know whether the value of the control is volatile
    (i.e. can change continuously) or not.

    Until now this was an internal property, but it is useful to know in
    userspace as well.

    A typical use case is the gain value when autogain is on. In that case the
    hardware will continuously adjust the gain based various environmental
    factors.

    This patch just adds and documents the flag, it's not yet used.

  • 7ee40aada   [media] v4l: removal of old, obsolete ioctls ... Browse Code »

    Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
    type of R/W arguments. They were fixed, but the old ioctl names are
    still there, maintained to avoid breaking binary compatibility:

    There's no sense on preserving those forever, as it is very doubtful
    that someone would try to use a such old binary with a modern kernel.
    Removing them will allow us to remove some magic done at the V4L ioctl
    handler.

    Note that any application compiled with a videodev2.h from 2.6.7 or later
    will be using the correct ioctls.

  • f8f3914cf   [media] v4l: Add multi-planar API definitions to the V4L2 API ... Browse Code »

    Multi-planar API is as a backwards-compatible extension of the V4L2 API,
    which allows video buffers to consist of one or more planes. Planes are
    separate memory buffers; each has its own mapping, backed by usually
    separate physical memory buffers.

    Many different uses for the multi-planar API are possible, examples
    include:
    - embedded devices requiring video components to be placed in physically
    separate buffers, e.g. for Samsung S3C/S5P SoC series' video codec,
    Y and interleaved Cb/Cr components reside in buffers in different
    memory banks;
    - applications may receive (or choose to store) video data of one video
    buffer in separate memory buffers; such data would have to be temporarily
    copied together into one buffer before passing it to a V4L2 device;
    - applications or drivers may want to pass metadata related to a buffer and
    it may not be possible to place it in the same buffer, together with video
    data.

  • 79c6ff93c   V4L/DVB: V4L2: add a generic function to find the nearest discrete format to the required one ... Browse Code »

    Many video drivers implement a fixed set of frame formats and thus face a task
    of finding the best match for a user-requested format. Implementing this in a
    generic function has also an advantage, that different drivers with similar
    supported format sets will select the same format for the user, which improves
    consistency across drivers.

  • 1f33de0f8   V4L/DVB: gspca_xirlink_cit: New gspca subdriver replacing v4l1 usbvideo/ibmcam.c ... Browse Code »

    The old usbvideo ibmcam driver needs to be replaced with a v4l2 driver
    preferably using the gspca webcam framework rather then the old usbvideo
    framework.

    This new gspca sub driver sets a first step in that direction. The ibmcam
    driver supports 4 different model webcams. This new driver (for now) only
    supports Model 3 cameras, as my test cam is a Model 3 cam, or so I thought.

    Upon reading:
    http://www.linux-usb.org/ibmcam/
    I learned that the IBM Netcamera Pro I have even though having the same
    usb id and the same bcd version is different from the Model 3 cameras
    supported by the ibmcam driver. So this new gscpa subdriver supports Model 3
    cameras (untested), and the IBM Netcamera Pro. Currently use with the
    IBM Netcamera Pro requires a module parameter. I hope to be able to
    autodetect which is which in the future.
