VINO

Video4Linux driver for VINO (Video In No Out)

Please send suggestions, documentation and patches to Ladislav Michl (ladis(at)linux-mips(dot)org).

: Check out Mikael Nousiainen's
: Mikael Nousiainen fixed clipping!
: It's time to show you some picture grabbed using VINO V4L driver. (Behind that table I'm hacking ;). (Picture taken before Mikael fixed clipping bug)).
: Converted to PCI DMA API. Commited to CVS.
: It works!
: Released for impatient hackers. Not ready for users!

VINO
Philips SAA7191B - digital multistandard colour decoder.
Philips SAA7197 - clock generator circuit for 7191 DMSD
Philips TDA8708A - video analog input interface.
Assigned I²C-bus addresses
I²C-bus allocation table
Digital video evaluation module - demonstrates the performance and functionality of the Philips Digital Multistandard Television Processing System. Also contains informations about DMSD initialization via I²C and gives a clue how is VINO input circuit probably designed.

You need linux-mips.org cvs kernel (use linux_2_4 branch). Apply patch, configure kernel

CONFIG_I2C=m
CONFIG_I2C_ALGO_SGI=m
CONFIG_VIDEO_DEV=m
CONFIG_VIDEO_VINO=m

build and install modules

make modules; make modules_install
modprobe vino

now you are ready to test it. I'm using utility for testing. You'll need this patch because VINO is using ARGB not RGBA pallete.

Patches welcome.

VINO can do only memory capture (overlays are not possible). Use Virtual DMA to transfer picture to graphics backend.

Ralf Baechle MIPS port leader for patience and suggestions
Guido Guenther author of XFree86 Newport driver who designed this page. In fact I stole it from
Jirka Jirout for IndyCam
Thiemo Seufer for help with driver debugging
David Woodhouse who explained me many internals of linux kernel. HAL2 driver would never work without him
