V4L/DVB (3599a): Move drivers/usb/media to drivers/media/video

Browse source 
Because of historic reasons, there are two separate directories with
V4L stuff. Most drivers are located at driver/media/video. However, some
code for USB Webcams were inserted under drivers/usb/media.

This makes difficult for module authors to know were things should be.
Also, makes Kconfig menu confusing for normal users.

This patch moves all V4L content under drivers/usb/media to
drivers/media/video, and fixes Kconfig/Makefile entries.

/* A driver for the D-Link DSB-R100 USB radio. The R100 plugs
into both the USB and an analog audio input, so this thing
only deals with initialisation and frequency setting, the
audio data has to be handled by a sound driver.
Major issue: I can't find out where the device reports the signal
strength, and indeed the windows software appearantly just looks
at the stereo indicator as well. So, scanning will only find
stereo stations. Sad, but I can't help it.
Also, the windows program sends oodles of messages over to the
device, and I couldn't figure out their meaning. My suspicion
is that they don't have any:-)

This file contains some additional information for the Philips and OEM webcams.
E-mail: [email protected] Last updated: 2004-01-19
Site: http://www.smcc.demon.nl/webcam/

* Philips PCA646
* Philips PCVC675
* Philips PCVC680
* Philips PCVC690
* Philips PCVC720/40

* Visionite VCS-UM100
* Visionite VCS-UC300
The main webpage for the Philips driver is at the address above. It contains
a lot of extra information, a FAQ, and the binary plugin 'PWCX'. This plugin
contains decompression routines that allow you to use higher image sizes and
framerates; in addition the webcam uses less bandwidth on the USB bus (handy
if you want to run more than 1 camera simultaneously). These routines fall
under a NDA, and may therefor not be distributed as source; however, its use
is completely optional.
You can build this code either into your kernel, or as a module. I recommend
the latter, since it makes troubleshooting a lot easier. The built-in
microphone is supported through the USB Audio class.
When you load the module you can set some default settings for the
camera; some programs depend on a particular image-size or -format and
don't know how to set it properly in the driver. The options are:
size
Can be one of 'sqcif', 'qsif', 'qcif', 'sif', 'cif' or
'vga', for an image size of resp. 128x96, 160x120, 176x144,
320x240, 352x288 and 640x480 (of course, only for those cameras that
support these resolutions).
fps
Specifies the desired framerate. Is an integer in the range of 4-30.
fbufs
This paramter specifies the number of internal buffers to use for storing
frames from the cam. This will help if the process that reads images from
the cam is a bit slow or momentarely busy. However, on slow machines it
only introduces lag, so choose carefully. The default is 3, which is
reasonable. You can set it between 2 and 5.
mbufs
This is an integer between 1 and 10. It will tell the module the number of
buffers to reserve for mmap(), VIDIOCCGMBUF, VIDIOCMCAPTURE and friends.
The default is 2, which is adequate for most applications (double
buffering).
Should you experience a lot of 'Dumping frame...' messages during
grabbing with a tool that uses mmap(), you might want to increase if.
However, it doesn't really buffer images, it just gives you a bit more
slack when your program is behind. But you need a multi-threaded or
forked program to really take advantage of these buffers.
The absolute maximum is 10, but don't set it too high! Every buffer takes
up 460 KB of RAM, so unless you have a lot of memory setting this to
something more than 4 is an absolute waste. This memory is only
allocated during open(), so nothing is wasted when the camera is not in
use.
power_save
When power_save is enabled (set to 1), the module will try to shut down
the cam on close() and re-activate on open(). This will save power and
turn off the LED. Not all cameras support this though (the 645 and 646
don't have power saving at all), and some models don't work either (they
will shut down, but never wake up). Consider this experimental. By
default this option is disabled.
compression (only useful with the plugin)
With this option you can control the compression factor that the camera
uses to squeeze the image through the USB bus. You can set the
parameter between 0 and 3:
0 = prefer uncompressed images; if the requested mode is not available
in an uncompressed format, the driver will silently switch to low
compression.
1 = low compression.
2 = medium compression.
3 = high compression.
High compression takes less bandwidth of course, but it could also
introduce some unwanted artefacts. The default is 2, medium compression.
See the FAQ on the website for an overview of which modes require
compression.
The compression parameter does not apply to the 645 and 646 cameras
and OEM models derived from those (only a few). Most cams honour this
parameter.
leds
This settings takes 2 integers, that define the on/off time for the LED
(in milliseconds). One of the interesting things that you can do with
this is let the LED blink while the camera is in use. This:
leds=500,500
will blink the LED once every second. But with:
leds=0,0
the LED never goes on, making it suitable for silent surveillance.
By default the camera's LED is on solid while in use, and turned off
when the camera is not used anymore.
This parameter works only with the ToUCam range of cameras (720, 730, 740,
750) and OEMs. For other cameras this command is silently ignored, and
the LED cannot be controlled.
Finally: this parameters does not take effect UNTIL the first time you
open the camera device. Until then, the LED remains on.
dev_hint
A long standing problem with USB devices is their dynamic nature: you
never know what device a camera gets assigned; it depends on module load
order, the hub configuration, the order in which devices are plugged in,
and the phase of the moon (i.e. it can be random). With this option you
can give the driver a hint as to what video device node (/dev/videoX) it
should use with a specific camera. This is also handy if you have two
cameras of the same model.
A camera is specified by its type (the number from the camera model,
like PCA645, PCVC750VC, etc) and optionally the serial number (visible
in /proc/bus/usb/devices). A hint consists of a string with the following
format:
[type[.serialnumber]:]node
The square brackets mean that both the type and the serialnumber are
optional, but a serialnumber cannot be specified without a type (which
would be rather pointless). The serialnumber is separated from the type
by a '.'; the node number by a ':'.
This somewhat cryptic syntax is best explained by a few examples:
dev_hint=3,5 The first detected cam gets assigned
/dev/video3, the second /dev/video5. Any
other cameras will get the first free
available slot (see below).
dev_hint=645:1,680:2 The PCA645 camera will get /dev/video1,
and a PCVC680 /dev/video2.
dev_hint=645.0123:3,645.4567:0 The PCA645 camera with serialnumber
0123 goes to /dev/video3, the same
camera model with the 4567 serial
gets /dev/video0.
dev_hint=750:1,4,5,6 The PCVC750 camera will get /dev/video1, the
next 3 Philips cams will use /dev/video4
through /dev/video6.
Some points worth knowing:
- Serialnumbers are case sensitive and must be written full, including
leading zeroes (it's treated as a string).
- If a device node is already occupied, registration will fail and
the webcam is not available.
- You can have up to 64 video devices; be sure to make enough device
nodes in /dev if you want to spread the numbers (this does not apply
to devfs). After /dev/video9 comes /dev/video10 (not /dev/videoA).
- If a camera does not match any dev_hint, it will simply get assigned
the first available device node, just as it used to be.
trace
In order to better detect problems, it is now possible to turn on a
'trace' of some of the calls the module makes; it logs all items in your
kernel log at debug level.
The trace variable is a bitmask; each bit represents a certain feature.
If you want to trace something, look up the bit value(s) in the table
below, add the values together and supply that to the trace variable.
Value Value Description Default
(dec) (hex)
1 0x1 Module initialization; this will log messages On
while loading and unloading the module
2 0x2 probe() and disconnect() traces On
4 0x4 Trace open() and close() calls Off
8 0x8 read(), mmap() and associated ioctl() calls Off
16 0x10 Memory allocation of buffers, etc. Off
32 0x20 Showing underflow, overflow and Dumping frame On
messages
64 0x40 Show viewport and image sizes Off
128 0x80 PWCX debugging Off
For example, to trace the open() & read() fuctions, sum 8 + 4 = 12,
so you would supply trace=12 during insmod or modprobe. If
you want to turn the initialization and probing tracing off, set trace=0.
The default value for trace is 35 (0x23).
Example:
# modprobe pwc size=cif fps=15 power_save=1
The fbufs, mbufs and trace parameters are global and apply to all connected
cameras. Each camera has its own set of buffers.
size and fps only specify defaults when you open() the device; this is to
accommodate some tools that don't set the size. You can change these
settings after open() with the Video4Linux ioctl() calls. The default of
defaults is QCIF size at 10 fps.
The compression parameter is semiglobal; it sets the initial compression
preference for all camera's, but this parameter can be set per camera with
the VIDIOCPWCSCQUAL ioctl() call.
All parameters are optional.

NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx

Please send bug reports and support requests to <luc@saillard.org>.
The decompression routines have been implemented by reverse-engineering the

/* This tables contains entries for the 675/680/690 (Timon) camera, with
4 different qualities (no compression, low, medium, high).
It lists the bandwidth requirements for said mode by its alternate interface
number. An alternate of 0 means that the mode is unavailable.
There are 6 * 4 * 4 entries:
6 different resolutions subqcif, qsif, qcif, sif, cif, vga
6 framerates: 5, 10, 15, 20, 25, 30
4 compression modi: none, low, medium, high
When an uncompressed mode is not available, the next available compressed mode
will be chosen (unless the decompressor is absent). Sometimes there are only
1 or 2 compressed modes available; in that case entries are duplicated.

/*
OVERVIEW.
This is a small interface that allows you to add support for any CCD/CMOS
image sensors connected to the SN9C10X bridges. The entire API is documented
below. In the most general case, to support a sensor there are three steps
you have to follow:
1) define the main "sn9c102_sensor" structure by setting the basic fields;
2) write a probing function to be called by the core module when the USB
camera is recognized, then add both the USB ids and the name of that
function to the two corresponding tables SENSOR_TABLE and ID_TABLE (see
below);
3) implement the methods that you want/need (and fill the rest of the main
structure accordingly).
"sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
NOT need to touch the source code of the core module for the things to work
properly, unless you find bugs or flaws in it. Finally, do not forget to
read the V4L2 API for completeness.
*/
/*****************************************************************************/
/*
Probing functions: on success, you must attach the sensor to the camera
by calling sn9c102_attach_sensor() provided below.
To enable the I2C communication, you might need to perform a really basic
initialization of the SN9C10X chip by using the write function declared
ahead.
Functions must return 0 on success, the appropriate error otherwise.

Think the image sensor as a grid of R,G,B monochromatic pixels

the complete array of pixels, from (0,0) to (xmax, ymax). We will
use this coordinate system from now on. It is assumed the sensor
chip can be programmed to capture/transmit a subsection of that
array of pixels: we will call this subsection "active window".
It is not always true that the largest achievable active window can
cover the whole array of pixels. The V4L2 API defines another
area called "source rectangle", which, in turn, is a subrectangle of
the active window. The SN9C10X chip is always programmed to read the
source rectangle.
The bounds of both the active window and the source rectangle are
specified in the cropcap substructures 'bounds' and 'defrect'.
By default, the source rectangle should cover the largest possible
area. Again, it is not always true that the largest source rectangle
can cover the entire active window, although it is a rare case for
the hardware we have. The bounds of the source rectangle _must_ be
multiple of 16 and must use the same coordinate system as indicated
before; their centers shall align initially.
If necessary, the sensor chip must be initialized during init() to
set the bounds of the active sensor window; however, by default, it
usually covers the largest achievable area (maxwidth x maxheight)
of pixels, so no particular initialization is needed, if you have
defined the correct default bounds in the structures.
See the V4L2 API for further details.
NOTE: once you have defined the bounds of the active window
(struct cropcap.bounds) you must not change them.anymore.
Only 'bounds' and 'defrect' fields are mandatory, other fields
will be ignored.

'rect' contains width and height values that are multiple of 16: in
case you override the default function, you always have to program
the chip to match those values; on error return the corresponding
error code without rolling back.
NOTE: in case, you must program the SN9C10X chip to get rid of
blank pixels or blank lines at the _start_ of each line or
frame after each HSYNC or VSYNC, so that the image starts with
real RGB data (see regs 0x12, 0x13) (having set H_SIZE and,

V4L2_PIX_FMT_SBGGR8 3) 'priv', which we'll be used to indicate the
number of bits per pixel for uncompressed video, 8 or 9 (despite the
current value of 'pixelformat').
NOTE 1: both 'width' and 'height' _must_ be either 1/1 or 1/2 or 1/4
of cropcap.defrect.width and cropcap.defrect.height. I
suggest 1/1.
NOTE 2: The initial compression quality is defined by the first bit
of reg 0x17 during the initialization of the image sensor.
NOTE 3: as said above, you have to program the SN9C10X chip to get
rid of any blank pixels, so that the output of the sensor
