2011-04-11uncompressed video formats have a fixed per-pixel bit depth, whichJacob Meuser
means the data size of a frame can be calculated if the dimensions are known. * calculate frame data sizes for uncompressed formats instead of believing what the hardware says. the UVC spec changed between 1.0 and 1.1, and as a result, some devices return bogus information. * skip under-sized as well as over-sized uncompressed frames; there is only one correct size for uncompressed frames. * remove quirk to fix uncompressed frame sizes on certain devices, since that now always happens. * check that the device is actually using the parameters we think it's using.
2011-04-04the v4l2 spec says that setting time per frame to zero should reset timeJacob Meuser
per frame to the default, so do that instead of returning EINVAL
2011-03-31just report the frame interval in the same terms the device gives us.Jacob Meuser
previously, this was returning the wrong value (frame rate instead of time per frame, d'oh!).
2011-03-26oops. the frame rate is the inverse of the frame interval. fixesJacob Meuser
setting the frame rate with luvcview.
2011-03-26use 'sizeof(struct usb_video_frame_desc)' instead of a hardcodedJacob Meuser
number
2011-03-26fill in the timestamp when copying a frame into the mmap bufferJacob Meuser
2011-03-26fill in support for VIDIOC_ENUM_FRAMEINTERVALSJacob Meuser
2011-03-26support VIDIOC_S_PARM and VIDIOC_G_PARM. these ioctls are used forJacob Meuser
setting and and getting the frame interval.
2011-03-26print the supported frame intervals when printing the frame descriptorJacob Meuser
2011-03-25* don't try to align our array of frame descriptors with theJacob Meuser
frame descriptor's bFrameIndex field. the first valid frame in the array is at index 0, not 1. * don't change the format group's default frame when configuring the device, and don't use the default frame as the current frame: these are what the format group's 'frame_cur' is for. tested by several as part of larger diff
2011-03-25* the mjpeg and uncompressed video frame descriptor structures areJacob Meuser
equivilent. only define one structure, struct usb_video_frame_desc, and handle both types of frame descriptors in the same code. * replace hardcoded numbers with 'sizeof(struct usb_video_frame_desc)' where the numbers represent the size of a frame descriptor tested by several
2011-03-25* empty the queue of frames in the mmap frame buffer and set theJacob Meuser
index of the current frame to -1 when the mmap frame buffer is free'd * set the index of the current frame to 0 when allocating the mmap frame buffer * paranoia: panic if a) the mmap frame buffer is already allocated when we try to allocate it, or b) the mmap frame buffer is not allocated when we try to add frames to it tested by several
2011-01-25garbage collect "usb events". without /dev/usb there is no way to accessJacob Meuser
them from userland, and nothing in the kernel uses them. ok krw@, miod@
2011-01-16* instead of NULLing pointers to interface descriptors in the uaa, markJacob Meuser
interfaces as being claimed in the usbd_device's copy of the interface descriptors * allow ugen(4) to be attached if there are unused interfaces in a configuration that has had drivers attached * make ugen(4) aware that it may be sharing a device with (an)other driver(s), and if so: * do not let ugen(4) change the configuration * do not let ugen(4) access the already claimed interfaces discussed with deraadt and miod
2010-11-24- use *un*signed byte array for control dataJacob Meuser
- use UGETW/USETW instead of letoh16/htole16 fixes controls that use two-byte signed data (e.g. brighness and hue) on sparc64
2010-10-23create another kthread to run xfer abort tasks. xfer abort tasks cannotJacob Meuser
be run from the generic task kthread, because xfers that need to be aborted block newly queued tasks from running (i.e. the xfer to be aborted blocks the abort of that task). as there are now three types of usb tasks, add an argument to usb_init_task() and another member to struct usb_task to specify the task type. fixes boot hangs that are showing up because we now use usb tasks to attach/detach usb devices.
2010-10-18bFrameIntervalType affects frame rates, not frame sizesJacob Meuser
2010-10-18when configuring the streaming interface with the video probe andJacob Meuser
commit controls, use the hardware frame idenfitier instead of the software identifier since they can differ, and the hardware only knows about it's own identifiers
2010-10-18use setting with closest matching bandwidth for the current configurationJacob Meuser
instead of the first one that has enough bandwidth as it may be too much
2010-10-09* define structure that represents USB descriptor with variable sizedJacob Meuser
member the way uaudio does, make the variable sized member as large as it can be and don't define the following members. * reenable control support for devices where bControlSize != 2 in the processing unit descriptor. tested on alpha, amd64, i386, sparc64 and zaurus, as well as the machine where previous support for variable bControlSize caused a hang.
2010-10-09control values can be 1 or 2 bytes, signed or unsigned. fixes hueJacob Meuser
control.
2010-10-08don't trust that bFrameIndex in frame descriptors is unique. fixesJacob Meuser
a crash with Kodak S100 webcam.
2010-09-29back out support for variable sized processing unit controls untilJacob Meuser
I can figure out why it causes boot hangs with some Sonix camera
2010-09-26support variable sized (bControlSize != 2) processing unit bmControls,Jacob Meuser
and add support for more processing unit controls. from Martin Pieuchot, thanks!
2010-09-12anonymous unions aren't standard C and don't work with gcc2. name theJacob Meuser
anonymous unions "un". delete some obsolete mpeg/jpeg compression methods that have never been supported, and will not need to be supported.

2009-02-21Fix a kernel crash for bulk devices when closing the video stream;Marcus Glocker
We give the kthread loop a moment to recognize that bulk_running=0 before we close the USB pipes. Otherwise it can happen that we close the USB pipes before the kthread loop stopped.
