2009-03-11libv4l: Adjust mr97310a for gspca mr97310a driver changeshans@rhel5-devel.localdomain
From: Theodore Kilgore <kilgota@auburn.edu> This patch introduces an offset of 12 bytes before starting the decompression of a frame. This needs to be done to compensate for a change in the gspca driver, where headers are now preserved instead of suppressed.

2009-03-11libv4l: add sn9c20x-i420 decoderhans@rhel5-devel.localdomain
From: Vasily Khoruzhick <anarsoul@gmail.com> Recent sn9c20x driver written by microdia project (http://groups.goolge.com/group/microdia) introduce new output format - sn9c20x-i420. This format is actually scrambled yuv420, so it's very easy and fast to convert it to yuv420. This patch adds sn9c20x-i420 decoder to the libv4l-0.5.7 This decoder is much faster than jpeg one (sn9c20x supports JPEG too): sn9c20x-i420 decoder eats only 10% of 1GHz CPU at 640x480x25fps vs 40% of 1GHz CPU in jpeg at same frame size/rate. This format should be preffered for sn9c20x, because sn9c20x driver supports SBGGR8 too, so it should go before SBGGR8 in supported_src_pixfmts.

2009-03-11libv4l: avoid try_fmt on UVC cams if possiblehans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> Avoid the use of try_fmt as much as possible on UVC cams, instead use the results of the enum_framesizes ioctl. This is because: 1) try_fmt actually causes IO with UVC cams making apps which do lot of querying of device capabilities slow (cheese) 2) some buggy cams don't like getting lots of UVC video probes and crash when they do Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2009-03-11libv4l: Add software cropping from CIF to VGA modes (fix skype)hans@rhel5-devel.localdomain
From: Hans de Goede <hdegoede@redhat.com> * Add support for software cropping from 352x288 -> 320x240 / 176x144 -> 160x120, so that apps which will only work with vga resolutions like 320x240 (Skype!) will work with cams/drivers which do not support cropping CIF resolutions to VGA resolutions in hardware. This makes all 2.6.27 gspca supported cams, except for the pac7302 which only does 640x480 (and skype wants 320x240), work with skype * The v4lconvert_convert function was becoming a bit of a mess, so split the functionailiy into seperate v4lconvert_convert_pixfmt, v4lconvert_rotate and v4lconvert_crop functions, and make v4lconvert_convert a frontend to these Priority: normal Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2009-01-27Add a small utility for retrieving sysfs bus pathMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> Thanks to Carsten Meier <cm@trexity.de> for providing us a c++ code snippet for USB. This code is capable of getting the bus info for both USB and PCI devices. This is retrieved via bus_info returned by VIDIOC_QUERYCAP. The utility will output the following info for a usb device: bus info = usb-0000:00:1d.7-1 bus path = /sys/devices/pci0000:00/0000:00:1d.7/usb2/2-1 And, for PCI devices, it will output: bus info = PCI:0000:01:02.0 bus path = /sys/devices/pci0000:00/0000:00:1e.0/0000:01:02.0 Notice: This will only work for devices that uses the standard notation for the bus info: on PCI: sprintf(cap->bus_info, "PCI:%s", pci_name(dev->pci)); or sprintf(cap->bus_info, "PCIe:%s", pci_name(dev->pci)); on USB: usb_make_path(dev->udev, cap->bus_info, sizeof(cap->bus_info)); Priority: normal Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only. Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged with a warning that it is deprecated and will be removed in 2.6.30.
