Overview and features -======================== -This driver supports the video interface of the devices mounting the ET61X151 -or ET61X251 PC Camera Controllers. - -It's worth to note that Etoms Electronics has never collaborated with the -author during the development of this project; despite several requests, -Etoms Electronics also refused to release enough detailed specifications of -the video compression engine. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the ET61X[12]51 driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- support for any window resolutions and optional panning within the maximum - pixel area of image sensor; -- image downscaling with arbitrary scaling factors from 1 and 2 in both - directions (see "Notes for V4L2 application developers" paragraph); -- two different video formats for uncompressed or compressed data in low or - high compression quality (see also "Notes for V4L2 application developers" - paragraph); -- full support for the capabilities of every possible image sensors that can - be connected to the ET61X[12]51 bridges, including, for instance, red, green, - blue and global gain adjustments and exposure control (see "Supported - devices" paragraph for details); -- use of default color settings for sunlight conditions; -- dynamic I/O interface for both ET61X[12]51 and image sensor control (see - "Optional device control through 'sysfs'" paragraph); -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; -- no known bugs. - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - -To enable advanced debugging functionality on the device through /sysfs: - - # Multimedia devices - # - CONFIG_VIDEO_ADV_DEBUG=y - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_ET61X251=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "et61x251" module into memory -after every other module required: "videodev", "v4l2_common", "compat_ioctl32", -"usbcore" and, depending on the USB host controller you have, "ehci-hcd", -"uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe et61x251 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - registered camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not - all the applications support this feature. This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: <n[,...]> -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: <n> -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant information - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used at the same time. It also shows some more information - about the hardware being detected. This module parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Optional device control through "sysfs" -========================================== -If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, -it is possible to read and write both the ET61X[12]51 and the image sensor -registers by using the "sysfs" filesystem interface. - -There are four files in the /sys/class/video4linux/videoX directory for each -registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files -control the ET61X[12]51 bridge, while the other two control the sensor chip. -"reg" and "i2c_reg" hold the values of the current register index where the -following reading/writing operations are addressed at through "val" and -"i2c_val". Their use is not intended for end-users, unless you know what you -are doing. Remember that you must be logged in as root before writing to them. - -As an example, suppose we were to want to read the value contained in the -register number 1 of the sensor register table - which is usually the product -identifier - of the camera registered as "/dev/video0": - - [root@localhost #] cd /sys/class/video4linux/video0 - [root@localhost #] echo 1 > i2c_reg - [root@localhost #] cat i2c_val - -Note that if the sensor registers cannot be read, "cat" will fail. -To avoid race conditions, all the I/O accesses to the files are serialized. - - -9. Supported devices -==================== -None of the names of the companies as well as their products will be mentioned -here. They have never collaborated with the author, so no advertising. - -From the point of view of a driver, what unambiguously identify a device are -its vendor and product USB identifiers.

Notes for V4L2 application developers -========================================= -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - -Consistently with the hardware limits, this driver also supports image -downscaling with arbitrary scaling factors from 1 and 2 in both directions. -However, the V4L2 API specifications don't correctly define how the scaling -factor can be chosen arbitrarily by the "negotiation" of the "source" and -"target" rectangles. To work around this flaw, we have added the convention -that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the -scaling factor is restored to 1. - -This driver supports two different video formats: the first one is the "8-bit -Sequential Bayer" format and can be used to obtain uncompressed video data -from the device through the current I/O method, while the second one provides -"raw" compressed video data (without frame headers not related to the -compressed data). The current compression quality may vary from 0 to 1 and can -be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP -V4L2 ioctl's. - - -11.

See http://xirlinkwebcam.sourceforge.net, -http://www.ibmpccamera.com, or http://www.c-itnow.com/ for details and pictures. - -This very chipset ("X Chip", as marked at the factory) -is used in several other cameras, and they are supported -as well: - -- IBM NetCamera -- Veo Stingray - -The Linux driver was developed with camera with following -model number (or FCC ID): KSX-XVP510. This camera has three -interfaces, each with one endpoint (control, iso, iso). This -type of cameras is referred to as "model 1". These cameras are -no longer manufactured. - -Xirlink now manufactures new cameras which are somewhat different. -In particular, following models [FCC ID] belong to that category: - -XVP300 [KSX-X9903] -XVP600 [KSX-X9902] -XVP610 [KSX-X9902] - -(see http://www.xirlink.com/ibmpccamera/ for updates, they refer -to these new cameras by Windows driver dated 12-27-99, v3005 BETA) -These cameras have two interfaces, one endpoint in each (iso, bulk). -Such type of cameras is referred to as "model 2". They are supported -(with exception of 352x288 native mode). - -Some IBM NetCameras (Model 4) are made to generate only compressed -video streams. This is great for performance, but unfortunately -nobody knows how to decompress the stream :-( Therefore, these -cameras are *unsupported* and if you try to use one of those, all -you get is random colored horizontal streaks, not the image! -If you have one of those cameras, you probably should return it -to the store and get something that is supported. - -Tell me more about all that "model" business --------------------------------------------- - -I just invented model numbers to uniquely identify flavors of the -hardware/firmware that were sold. It was very confusing to use -brand names or some other internal numbering schemes. So I found -by experimentation that all Xirlink chipsets fall into four big -classes, and I called them "models". Each model is programmed in -its own way, and each model sends back the video in its own way. - -Quirks of Model 2 cameras: -------------------------- - -Model 2 does not have hardware contrast control. Corresponding V4L -control is implemented in software, which is not very nice to your -CPU, but at least it works. - -This driver provides 352x288 mode by switching the camera into -quasi-352x288 RGB mode (800 Kbits per frame) essentially limiting -this mode to 10 frames per second or less, in ideal conditions on -the bus (USB is shared, after all). The frame rate -has to be programmed very conservatively. Additional concern is that -frame rate depends on brightness setting; therefore the picture can -be good at one brightness and broken at another! I did not want to fix -the frame rate at slowest setting, but I had to move it pretty much down -the scale (so that framerate option barely matters). I also noticed that -camera after first powering up produces frames slightly faster than during -consecutive uses. All this means that if you use 352x288 (which is -default), be warned - you may encounter broken picture on first connect; -try to adjust brightness - brighter image is slower, so USB will be able -to send all data. However if you regularly use Model 2 cameras you may -prefer 176x144 which makes perfectly good I420, with no scaling and -lesser demands on USB (300 Kbits per second, or 26 frames per second). - -Another strange effect of 352x288 mode is the fine vertical grid visible -on some colored surfaces. I am sure it is caused by me not understanding -what the camera is trying to say. Blame trade secrets for that. - -The camera that I had also has a hardware quirk: if disconnected, -it needs few minutes to "relax" before it can be plugged in again -(poorly designed USB processor reset circuit?) - -[Veo Stingray with Product ID 0x800C is also Model 2, but I haven't -observed this particular flaw in it.] - -Model 2 camera can be programmed for very high sensitivity (even starlight -may be enough), this makes it convenient for tinkering with. The driver -code has enough comments to help a programmer to tweak the camera -as s/he feels necessary. - -WHAT YOU NEED: - -- A supported IBM PC (C-it) camera (model 1 or 2) - -- A Linux box with USB support (2.3/2.4; 2.2 w/backport may work) - -- A Video4Linux compatible frame grabber program such as xawtv. - -HOW TO COMPILE THE DRIVER: - -You need to compile the driver only if you are a developer -or if you want to make changes to the code. Most distributions -precompile all modules, so you can go directly to the next -section "HOW TO USE THE DRIVER". - -The ibmcam driver uses usbvideo helper library (module), -so if you are studying the ibmcam code you will be led there. - -The driver itself consists of only one file in usb/ directory: -ibmcam.c. This file is included into the Linux kernel build -process if you configure the kernel for CONFIG_USB_IBMCAM. -Run "make xconfig" and in USB section you will find the IBM -camera driver. Select it, save the configuration and recompile. - -HOW TO USE THE DRIVER: - -I recommend to compile driver as a module. This gives you an -easier access to its configuration. The camera has many more -settings than V4L can operate, so some settings are done using -module options. - -To begin with, on most modern Linux distributions the driver -will be automatically loaded whenever you plug the supported -camera in. Therefore, you don't need to do anything. However -if you want to experiment with some module parameters then -you can load and unload the driver manually, with camera -plugged in or unplugged. - -Typically module is installed with command 'modprobe', like this: - -# modprobe ibmcam framerate=1 - -Alternatively you can use 'insmod' in similar fashion: - -# insmod /lib/modules/2.x.y/usb/ibmcam.o framerate=1 - -Module can be inserted with camera connected or disconnected. - -The driver can have options, though some defaults are provided. - -Driver options: (* indicates that option is model-dependent) - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -debug Integer 0-9 [0] debug=1 -flags Integer 0-0xFF [0] flags=0x0d -framerate Integer 0-6 [2] framerate=1 -hue_correction Integer 0-255 [128] hue_correction=115 -init_brightness Integer 0-255 [128] init_brightness=100 -init_contrast Integer 0-255 [192] init_contrast=200 -init_color Integer 0-255 [128] init_color=130 -init_hue Integer 0-255 [128] init_hue=115 -lighting Integer 0-2* [1] lighting=2 -sharpness Integer 0-6* [4] sharpness=3 -size Integer 0-2* [2] size=1 - -Options for Model 2 only: - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -init_model2_rg Integer 0..255 [0x70] init_model2_rg=128 -init_model2_rg2 Integer 0..255 [0x2f] init_model2_rg2=50 -init_model2_sat Integer 0..255 [0x34] init_model2_sat=65 -init_model2_yb Integer 0..255 [0xa0] init_model2_yb=200 - -debug You don't need this option unless you are a developer. - If you are a developer then you will see in the code - what values do what. 0=off. - -flags This is a bit mask, and you can combine any number of - bits to produce what you want. Usually you don't want - any of extra features this option provides: - - FLAGS_RETRY_VIDIOCSYNC 1 This bit allows to retry failed - VIDIOCSYNC ioctls without failing. - Will work with xawtv, will not - with xrealproducer. Default is - not set. - FLAGS_MONOCHROME 2 Activates monochrome (b/w) mode. - FLAGS_DISPLAY_HINTS 4 Shows colored pixels which have - magic meaning to developers. - FLAGS_OVERLAY_STATS 8 Shows tiny numbers on screen, - useful only for debugging. - FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers. - FLAGS_SEPARATE_FRAMES 32 Shows each frame separately, as - it was received from the camera. - Default (not set) is to mix the - preceding frame in to compensate - for occasional loss of Isoc data - on high frame rates. - FLAGS_CLEAN_FRAMES 64 Forces "cleanup" of each frame - prior to use; relevant only if - FLAGS_SEPARATE_FRAMES is set. - Default is not to clean frames, - this is a little faster but may - produce flicker if frame rate is - too high and Isoc data gets lost. - FLAGS_NO_DECODING 128 This flag turns the video stream - decoder off, and dumps the raw - Isoc data from the camera into - the reading process. Useful to - developers, but not to users. - -framerate This setting controls frame rate of the camera. This is - an approximate setting (in terms of "worst" ... "best") - because camera changes frame rate depending on amount - of light available. Setting 0 is slowest, 6 is fastest. - Beware - fast settings are very demanding and may not - work well with all video sizes. Be conservative. - -hue_correction This highly optional setting allows to adjust the - hue of the image in a way slightly different from - what usual "hue" control does. Both controls affect - YUV colorspace: regular "hue" control adjusts only - U component, and this "hue_correction" option similarly - adjusts only V component. However usually it is enough - to tweak only U or V to compensate for colored light or - color temperature; this option simply allows more - complicated correction when and if it is necessary. - -init_brightness These settings specify _initial_ values which will be -init_contrast used to set up the camera. If your V4L application has -init_color its own controls to adjust the picture then these -init_hue controls will be used too. These options allow you to - preconfigure the camera when it gets connected, before - any V4L application connects to it. Good for webcams. - -init_model2_rg These initial settings alter color balance of the -init_model2_rg2 camera on hardware level. All four settings may be used -init_model2_sat to tune the camera to specific lighting conditions. These -init_model2_yb settings only apply to Model 2 cameras. - -lighting This option selects one of three hardware-defined - photosensitivity settings of the camera. 0=bright light, - 1=Medium (default), 2=Low light. This setting affects - frame rate: the dimmer the lighting the lower the frame - rate (because longer exposition time is needed). The - Model 2 cameras allow values more than 2 for this option, - thus enabling extremely high sensitivity at cost of frame - rate, color saturation and imaging sensor noise. - -sharpness This option controls smoothing (noise reduction) - made by camera. Setting 0 is most smooth, setting 6 - is most sharp. Be aware that CMOS sensor used in the - camera is pretty noisy, so if you choose 6 you will - be greeted with "snowy" image. Default is 4. Model 2 - cameras do not support this feature. - -size This setting chooses one of several image sizes that are - supported by this driver. Cameras may support more, but - it's difficult to reverse-engineer all formats. - Following video sizes are supported: - - size=0 128x96 (Model 1 only) - size=1 160x120 - size=2 176x144 - size=3 320x240 (Model 2 only) - size=4 352x240 (Model 2 only) - size=5 352x288 - size=6 640x480 (Model 3 only) - - The 352x288 is the native size of the Model 1 sensor - array, so it's the best resolution the camera can - yield. The best resolution of Model 2 is 176x144, and - larger images are produced by stretching the bitmap. - Model 3 has sensor with 640x480 grid, and it works too, - but the frame rate will be exceptionally low (1-2 FPS); - it may be still OK for some applications, like security. - Choose the image size you need. The smaller image can - support faster frame rate.

This feature is not yet implemented. - - NAME: debug - TYPE: integer (0-6) - DEFAULT: 3 - DESC: Sets the threshold for printing debug messages. The higher the value, - the more is printed. The levels are cumulative, and are as follows: - 0=no debug messages - 1=init/detection/unload and other significant messages - 2=some warning messages - 3=config/control function calls - 4=most function calls and data parsing messages - 5=highly repetitive mesgs - - NAME: snapshot - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set to 1 to enable snapshot mode. read()/VIDIOCSYNC will block until - the snapshot button is pressed. Note: enabling this mode disables - /proc/video/ov511/<minor#>/button - - NAME: cams - TYPE: integer (1-4 for OV511, 1-31 for OV511+) - DEFAULT: 1 - DESC: Number of cameras allowed to stream simultaneously on a single bus. - Values higher than 1 reduce the data rate of each camera, allowing two - or more to be used at once. If you have a complicated setup involving - both OV511 and OV511+ cameras, trial-and-error may be necessary for - finding the optimum setting. - - NAME: compress - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set this to 1 to turn on the camera's compression engine. This can - potentially increase the frame rate at the expense of quality, if you - have a fast CPU. You must load the proper compression module for your - camera before starting your application (ov511_decomp or ov518_decomp). - - NAME: testpat - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: This configures the camera's sensor to transmit a colored test-pattern - instead of an image. This does not work correctly yet. - - NAME: dumppix - TYPE: integer (0-2) - DEFAULT: 0 - DESC: Dumps raw pixel data and skips post-processing and format conversion. - It is for debugging purposes only. Options are: - 0: Disable (default) - 1: Dump raw data from camera, excluding headers and trailers - 2: Dumps data exactly as received from camera - - NAME: led - TYPE: integer (0-2) - DEFAULT: 1 (Always on) - DESC: Controls whether the LED (the little light) on the front of the camera - is always off (0), always on (1), or only on when driver is open (2). - This is not supported with the OV511, and might only work with certain - cameras (ones that actually have the LED wired to the control pin, and - not just hard-wired to be on all the time). - - NAME: dump_bridge - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the bridge (OV511[+] or OV518[+]) register values to the system - log. Only useful for serious debugging/development purposes. - - NAME: dump_sensor - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the sensor register values to the system log. Only useful for - serious debugging/development purposes. - - NAME: printph - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Setting this to 1 will dump the first 12 bytes of each isoc frame. This - is only useful if you are trying to debug problems with the isoc data - stream (i.e.: camera initializes, but vidcat hangs until Ctrl-C). Be - warned that this dumps a large number of messages to your kernel log. - - NAME: phy, phuv, pvy, pvuv, qhy, qhuv, qvy, qvuv - TYPE: integer (0-63 for phy and phuv, 0-255 for rest) - DEFAULT: OV511 default values - DESC: These are registers 70h - 77h of the OV511, which control the - prediction ranges and quantization thresholds of the compressor, for - the Y and UV channels in the horizontal and vertical directions. See - the OV511 or OV511+ data sheet for more detailed descriptions. These - normally do not need to be changed. - - NAME: lightfreq - TYPE: integer (0, 50, or 60) - DEFAULT: 0 (use sensor default) - DESC: Sets the sensor to match your lighting frequency. This can reduce the - appearance of "banding", i.e. horizontal lines or waves of light and - dark that are often caused by artificial lighting. Valid values are: - 0 - Use default (depends on sensor, most likely 60 Hz) - 50 - For European and Asian 50 Hz power - 60 - For American 60 Hz power - - NAME: bandingfilter - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enables the sensor´s banding filter exposure algorithm. This reduces - or stabilizes the "banding" caused by some artificial light sources - (especially fluorescent). You might have to set lightfreq correctly for - this to work right. As an added bonus, this sometimes makes it - possible to capture your monitor´s output. - - NAME: fastset - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Allows picture settings (brightness, contrast, color, and hue) to take - effect immediately, even in the middle of a frame. This reduces the - time to change settings, but can ruin frames during the change. Only - affects OmniVision sensors. - - NAME: force_palette - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Forces the palette (color format) to a specific value. If an - application requests a different palette, it will be rejected, thereby - forcing it to try others until it succeeds. This is useful for forcing - greyscale mode with a color camera, for example. Supported modes are: - 0 (Allows all the following formats) - 1 VIDEO_PALETTE_GREY (Linear greyscale) - 10 VIDEO_PALETTE_YUV420 (YUV 4:2:0 Planar) - 15 VIDEO_PALETTE_YUV420P (YUV 4:2:0 Planar, same as 10) - - NAME: backlight - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this flag changes the exposure algorithm for OmniVision sensors - such that objects in the camera's view (i.e. your head) can be clearly - seen when they are illuminated from behind. It reduces or eliminates - the sensor's auto-exposure function, so it should only be used when - needed. Additionally, it is only supported with the OV6620 and OV7620. - - NAME: unit_video - TYPE: Up to 16 comma-separated integers - DEFAULT: 0,0,0... (automatically assign the next available minor(s)) - DESC: You can specify up to 16 minor numbers to be assigned to ov511 devices. - For example, "unit_video=1,3" will make the driver use /dev/video1 and - /dev/video3 for the first two devices it detects. Additional devices - will be assigned automatically starting at the first available device - node (/dev/video0 in this case). Note that you cannot specify 0 as a - minor number. This feature requires kernel version 2.4.5 or higher. - - NAME: remove_zeros - TYPE: integer (Boolean) - DEFAULT: 0 (do not skip any incoming data) - DESC: Setting this to 1 will remove zero-padding from incoming data. This - will compensate for the blocks of corruption that can appear when the - camera cannot keep up with the speed of the USB bus (eg. at low frame - resolutions). This feature is always enabled when compression is on. - - NAME: mirror - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this to 1 will reverse ("mirror") the image horizontally. This - might be necessary if your camera has a custom lens assembly. This has - no effect with video capture devices. - - NAME: ov518_color - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enable OV518 color support. This is off by default since it doesn't - work most of the time. If you want to try it, you must also load - ov518_decomp with the "nouv=0" parameter. If you get improper colors or - diagonal lines through the image, restart your video app and try again. - Repeat as necessary. - -WORKING FEATURES: - o Color streaming/capture at most widths and heights that are multiples of 8. - o Monochrome (use force_palette=1 to enable) - o Setting/getting of saturation, contrast, brightness, and hue (only some of - them work the OV7620 and OV7620AE) - o /proc status reporting - o SAA7111A video capture support at 320x240 and 640x480 - o Compression support - o SMP compatibility - -HOW TO CONTACT ME: - -You can email me at mark@alpha.dyndns.org .

Overview -=========== -This driver supports the video streaming capabilities of the devices mounting -Winbond W9967CF and Winbond W9968CF JPEG USB Dual Mode Camera Chips. OV681 -based cameras should be supported as well. - -The driver is divided into two modules: the basic one, "w9968cf", is needed for -the supported devices to work; the second one, "w9968cf-vpp", is an optional -module, which provides some useful video post-processing functions like video -decoding, up-scaling and colour conversions. - -Note that the official kernels do neither include nor support the second -module for performance purposes. Therefore, it is always recommended to -download and install the latest and complete release of the driver, -replacing the existing one, if present. - -The latest and full-featured version of the W996[87]CF driver can be found at: -http://www.linux-projects.org. Please refer to the documentation included in -that package, if you are going to use it. - -Up to 32 cameras can be handled at the same time. They can be connected and -disconnected from the host many times without turning off the computer, if -your system supports the hotplug facility. - -To change the default settings for each camera, many parameters can be passed -through command line when the module is loaded into memory. - -The driver relies on the Video4Linux, USB and I2C core modules. It has been -designed to run properly on SMP systems as well. An additional module, -"ovcamchip", is mandatory; it provides support for some OmniVision image -sensors connected to the W996[87]CF chips; if found in the system, the module -will be automatically loaded by default (provided that the kernel has been -compiled with the automatic module loading option). - - -5. Supported devices -==================== -At the moment, known W996[87]CF and OV681 based devices are: -- Aroma Digi Pen VGA Dual Mode ADG-5000 (unknown image sensor) -- AVerMedia AVerTV USB (SAA7111A, Philips FI1216Mk2 tuner, PT2313L audio chip) -- Creative Labs Video Blaster WebCam Go (OmniVision OV7610 sensor) -- Creative Labs Video Blaster WebCam Go Plus (OmniVision OV7620 sensor) -- Lebon LDC-035A (unknown image sensor) -- Ezonics EZ-802 EZMega Cam (OmniVision OV8610C sensor) -- OmniVision OV8610-EDE (OmniVision OV8610 sensor) -- OPCOM Digi Pen VGA Dual Mode Pen Camera (unknown image sensor) -- Pretec Digi Pen-II (OmniVision OV7620 sensor) -- Pretec DigiPen-480 (OmniVision OV8610 sensor) - -If you know any other W996[87]CF or OV681 based cameras, please contact me. - -The list above does not imply that all those devices work with this driver: up -until now only webcams that have an image sensor supported by the "ovcamchip" -module work. Kernel messages will always tell you whether this is case. - -Possible external microcontrollers of those webcams are not supported: this -means that still images cannot be downloaded from the device memory. - -Furthermore, it's worth to note that I was only able to run tests on my -"Creative Labs Video Blaster WebCam Go". Donations of other models, for -additional testing and full support, would be much appreciated. - - -6. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux, USB -and I2C, and the "ovcamchip" module for the image sensor. Make sure you are not -actually using any external "ovcamchip" module, given that the W996[87]CF -driver depends on the version of the module present in the official kernels. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - - # I2C support - # - CONFIG_I2C=m - -The I2C core module can be compiled statically in the kernel as well. - - # OmniVision Camera Chip support - # - CONFIG_VIDEO_OVCAMCHIP=m - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, only one of the modules -below is necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_W9968CF=m - - -7. Module loading -================= -To use the driver, it is necessary to load the "w9968cf" module into memory -after every other module required. - -Loading can be done this way, from root: - - [root@localhost home]# modprobe usbcore - [root@localhost home]# modprobe i2c-core - [root@localhost home]# modprobe videodev - [root@localhost home]# modprobe w9968cf - -At this point the pertinent devices should be recognized: "dmesg" can be used -to analyze kernel messages: - - [user@localhost home]$ dmesg - -There are a lot of parameters the module can use to change the default -settings for each device. To list every possible parameter with a brief -explanation about them and which syntax to use, it is recommended to run the -"modinfo" command: - - [root@locahost home]# modinfo w9968cf - - -8.

Notes for V4L2 application developers -======================================== -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - - -10.

Much of the functions provided +by the VPFE, however, does not fall under the standard IOCTL's. + +In general, there is a private ioctl for configuring each of the blocks +containing hardware-dependent functions. + +The following private IOCTLs are supported: + + VIDIOC_VPFE_ISIF_[S/G]_RAW_PARAMS + VIDIOC_VPFE_IPIPE_[S/G]_CONFIG + VIDIOC_VPFE_RSZ_[S/G]_CONFIG + +The parameter structures used by these ioctl's are described in +include/uapi/linux/davinci_vpfe.h. + +The VIDIOC_VPFE_ISIF_S_RAW_PARAMS, VIDIOC_VPFE_IPIPE_S_CONFIG and +VIDIOC_VPFE_RSZ_S_CONFIG are used to configure, enable and disable functions in +the isif, ipipe and resizer blocks respectively. These IOCTL's control several +functions in the blocks they control. VIDIOC_VPFE_ISIF_S_RAW_PARAMS IOCTL +accepts a pointer to struct vpfe_isif_raw_config as its argument. Similarly +VIDIOC_VPFE_IPIPE_S_CONFIG accepts a pointer to struct vpfe_ipipe_config. And +VIDIOC_VPFE_RSZ_S_CONFIG accepts a pointer to struct vpfe_rsz_config as its +argument. Similarly VIDIOC_VPFE_ISIF_G_RAW_PARAMS, VIDIOC_VPFE_IPIPE_G_CONFIG +and VIDIOC_VPFE_RSZ_G_CONFIG are used to get the current configuration set in +the isif, ipipe and resizer blocks respectively. + +The detailed functions of the VPFE itself related to a given VPFE block is +described in the Technical Reference Manuals (TRMs) --- see the end of the +document for those. + + +IPIPEIF block IOCTLs +====================================== + +The following private IOCTLs are supported: + + VIDIOC_VPFE_IPIPEIF_[S/G]_CONFIG + +The parameter structures used by these ioctl's are described in +include/uapi/linux/dm365_ipipeif.h + +The VIDIOC_VPFE_IPIPEIF_S_CONFIG is used to configure the ipipeif +hardware block.
