DVC80 Dazzle zoran/nogatech driver

Observe that a download is available for USBVISION-0.9.8-1 which supports the subject USB device.

The indications in the README are that the ..zoran/nogatech usbvision..video must be enabled in the kernel. Also ...I2c API is referenced.

I find only a reference to ....CONFIG_VIDEO_ZORAN ..is not set..... in the kkernel26 config.

Has anyone utilized the USBVISION-0.9.8-1 download in arch?

Readme for kernel 2.6.x Linux device driver for the Zoran/Nogatech USBVision Video Grabber
------------------------------------------------------------------------------------------

Author: Joerg Heckenbach <joerg@heckenbach-aw.de>
Homepage: http://www.emuit.com/webcam.html (Dwaine Garden)



INTRODUCTION:
-------------

This is a driver for the USB video bridge USBVision from Zoran/Nogatech, a USB-only cable used in many "webcam" devices.
It supports streaming and capture of color or monochrome video via the Video4Linux
API. Most V4L apps are compatible with it, but a few video-conferencing programs
do not work yet.

If you need more information, please visit the Zoran/Nogatech homepage at the above URL.

usbvision-0.9.6 is the first prerelease of the 1.0 driver. I did many changes in the code and I hope I
didn't break working features on different devices. The decompression is completed. Just from time to
time there are some black or white error pixels in the image on slower machines. Maybe it is a timing problem
in the isoc interrupt routine. We stay a third of the time in interrupt and so it is likely, that the parser
is called twice. Let me cleanup the routine for performance, move the parser to user-context and add a lock.

For 2.6x kernels we can use the saa7111 from the kernel tree, so the make will not compile the saa7111-new
for these kernels.  The bt819-new.c is not coded to 2.6. kernel yet.
I have tested the driver with kernel 2.6.1, 2.6.2 to 2.6.7 with devices "Hauppauge WinTV USB FM 1" and
"Pixelview PlayTV USB Pro FM" on a 600MHz PII system.



WHAT YOU NEED:
--------------

- If you want to help with the development, get the chip's specification docs at
  http://www.emuit.com/webcam.html

- A Video4Linux compatible frame grabber program (I recommend xawtv or Kwintv)
  xawtv is available at:  http://www.in-berlin.de/User/kraxel/xawtv.html
 
- Radio Application to take advantage of the radio tuner. (some of the devices)
  GQradio is available at:  http://gqmpeg.sourceforge.net/radio.html



HOW TO INSTALL THE DEVICE DRIVER:
---------------------------------


First way (The easy one)
---------

It works with most modern standard installations.

a) In the usbvision directory do
   make; make install; modprobe usbvision

b) Start your video application.

c) Enjoy.

If c) doesn't work, something went wrong ;-)




Second way (Not as easy as the first one)
----------

You need this, if either usb-, i2c-, tuner- or v4l-support is missing in your kernel.

a) cp the following files into the directory /usr/src/linux/drivers/usb/media

    usbvision.c
    usbvision.h
    saa7113.c
    i2c-algo-usb.c
    i2c-algo-usb.h
    usbvision_ioctl.h


c) In the makefile of the dir /usr/src/linux/drivers/usb, look for the line "obj-$(CONFIG_USB_IBMCAM)    +=media/",
insert an additional line then added the line for the usbvision driver

   obj-$(CONFIG_USB_USBVISION)    += media/

e) Add the line to the makefile in /usr/src/linux/driver/usb/media/
  obj-$(CONFIG_USB_USBVISION)     += usbvision.o saa7113.o i2c-algo-usb.o

f) Edit file /usr/src/linux/drivers/usb/media/Kconfig   
   Paste the following lines below after the entry for the IBMCAM.

---------------------------- Begin Paste ------------------------------
config USB_USBVISION
    tristate "USB Zoran/Nogatech USBVision Video Grabber Support"
    depends on USB && VIDEO_DEV && I2C && VIDEO_BT848 && VIDEO_DPC
    ---help---
        Say Y here if you want to connect a Nogatech NT100x, or a Zoran
        ZR36504/ZR36505 chipset based video/tv/radio grabber, to your
        computer's USB port.

        For more information, read <file:Documentation/usb/usbvision.txt>.
      
        This driver needs the following support: Please enable (Y or M in config)
          Video For Linux API
        I2C API. 
        BT484 Device Support
        DPC7146 demonstration board Device Support
            
        This code is also available as a module ( = code which can be
        inserted in and removed from the running kernel whenever you want).
        The module will be called usbvision.o.  If you want to compile it as a
        module, say M here and read <file:Documentation/modules.txt>. This
        video grabber has several configuration options which can be specified
        when you load the module.  Read <file:Documentation/usb/usbvision.txt> to
        learn more.
---------------------------- End of Paste -----------------------------


h) If it is not already there (it usually is), create the video device:

    mknod /dev/video c 81 0

i) Sometimes /dev/video is a symlink to /dev/video0

You will have to set permissions on this device to allow you to read/write
from it:

    chmod 666 /dev/video
    chmod 666 /dev/video0 (if necessary)

When configuring the kernel choose Zoran/Nogatech USBVISION video support as
module. You are going to need also to select i2c and v4l, and if your
device have tuner you need to compile also BT848 support or other modules
that compile the tuner.o module.

    a) Do a make modules, make modules_install.

    b) If the USB Support and the Video4Linux was compiled as modules.

       modprobe usbcore.o
           modprobe usb-uhci.o  <OR>  modprobe ohci-hcd.o
       modprobe videodev.o

    b) Install the modules:

          modprobe usbvision- For a great radio application, try GQradio.

       The usbvision module will also load the i2c-algo-usb, i2c-core, saa7111, saa7113.


VIDEO PLAYERS FOR PLAYING VIDEO OUPUT
-------------------------------------

Here is the setting to get the TV tuner working with mplayer.  It does software video scaling, so you can have full screen mode with the USBVision driver.

    mplayer tv:// -tv channel=43:driver=v4l:input=0:outfmt=rgb24:norm=ntsc:height=240:width=320 -flip

Here is the setting to get the TV tuner working with xawtv.

    xawtv -c /dev/video0



USBVISION MODULE PARAMETERS:
----------------------------

  NAME: isocMode
  TYPE: integer (0x03, 0x14, 0x60)
  DEFAULT: 0x60
  DESC:  The isocMode is the format mode of the data that is transmitted on the isocronous
  pipe via USB. It is not depending on the connected video-hardware. Default is 0x14.

        YUV422          0x03
        YUV420          0x14
        COMPRESSION     0x60    Enable compression for full framerate.


  NAME: debug
  TYPE: bitmask
  DEFAULT: 0
  DESC: 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. This is a bit mask, and you can combine any
  number of bits to produce what you want:

       bit 2    debug procfs
       bit 3    debug video ioctl
       bit 4    debug video io
       bit 5    debug radio io
       bit 7    debug usb frame header
       bit 8    debug probe and disconnect
       bit 9    debug irq
       bit 10   debug handling of isochronus transfer
       bit 11   debug parsing of usb data
       bit 12   debug handling of scratch
       bit 13   debug utility functions
       bit 14   debug i2c stuff


  NAME: flags
  TYPE: bitmask
  DEFAULT: 0
  DESC: 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:

       bit 0    FLAGS_RETRY_VIDIOCSYNC     This bit allows to retry failed
                                           VIDIOCSYNC ioctls without failing.
                                           Will work with xawtv, will not
                                           with xrealproducer. Default is
                                           not set.
       bit 1    FLAGS_MONOCHROME           Activates monochrome (b/w) mode.
       bit 2    FLAGS_DISPLAY_HINTS        Shows colored pixels which have
                                           magic meaning to developers.
       bit 3    FLAGS_OVERLAY_STATS        Shows tiny numbers on screen,
                                           useful only for debugging.
       bit 4    FLAGS_FORCE_TESTPATTERN    Shows blue screen with numbers.
       bit 5    FLAGS_SEPARATE_FRAMES      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.
       bit 6    FLAGS_CLEAN_FRAMES         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.


  NAME: dga
  TYPE: integer (0-1) boolean
  DEFAULT: 1
  DESC: This will set the option for DGA video to either Yes or No.  Default is 1.


  NAME: PowerOnAtOpen
  TYPE: integer (0-1) boolean
  DEFAULT: 1
  DESC: This will set the device to power on automatically when opened.  Default is 1.


  NAME: SwitchSVideoInput
  TYPE: integer (0-1) boolean
  DEFAULT: 0
  DESC: To help people with Black and White output with using s-video input.  Some cables and input devices are wired differently. 
        If you are getting a black and white image when using the S-Video input.  Set this parameter to 1.  Default is 0, since most
    devices do not have this problem.


  NAME: CustomDevice
  TYPE: string
  DEFAULT: NULL
  DESC: This will set a new Custom device

================================================================================================

FINAL NOTE:
-----------

If your device isn't known, add it to usbvision_device_data and usbvision_table in usbvision.h.

You can speed up tuner detection, when adding "options tuner addr=your_addr" to /etc/modules.conf.

If your device isn't known, edit line (modprobe usbvision CustomDevice="0x0573 0x4D31 0 7113 3 PAL 1 1 1 5 -1 -1 -1 -1 -1")
in 'usbvision.rc' file then 'usbvision.rc start'
also edit "etc/rc.d/init.d/usbvision" if you use it

Please tell me your experience (joerg@heckenbach-aw.de), or contact (dwainegarden@rogers.com).
=========================================================
Can this device driver be utilized in kernel26-2.6.15-ARCH?
