What: Video4Linux API 1 ioctls and from Video devices.
When: kernel 2.6.38
Files: include/linux/videodev.h
Check: include/linux/videodev.h
Why: V4L1 AP1 was replaced by V4L2 API during migration from 2.4 to 2.6
series. The old API have lots of drawbacks and don't provide enough
means to work with all video and audio standards. The newer API is
already available on the main drivers and should be used instead.
Newer drivers should use v4l_compat_translate_ioctl function to handle
old calls, replacing to newer ones.
Decoder iocts are using internally to allow video drivers to
communicate with video decoders. This should also be improved to allow
V4L2 calls being translated into compatible internal ioctls.
Compatibility ioctls will be provided, for a while, via
v4l1-compat module.

Why: There are some drivers still using V4L1 API, despite all efforts we've done
to migrate. Those drivers are for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy. They probably have no practical usage today,
and people with such old hardware could probably keep using an older version
of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody
care enough to port and test them with V4L2 API, they'll be removed on 2.6.38.

What: Video4Linux: Remove obsolete ioctl's
When: kernel 2.6.39
Files: include/media/videodev2.h
Why: Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:
#define VIDIOC_OVERLAY_OLD _IOWR('V', 14, int)
#define VIDIOC_S_PARM_OLD _IOW('V', 22, struct v4l2_streamparm)
#define VIDIOC_S_CTRL_OLD _IOW('V', 28, struct v4l2_control)
#define VIDIOC_G_AUDIO_OLD _IOWR('V', 33, struct v4l2_audio)
#define VIDIOC_G_AUDOUT_OLD _IOWR('V', 49, struct v4l2_audioout)
#define VIDIOC_CROPCAP_OLD _IOR('V', 58, struct v4l2_cropcap)
There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.

This is a driver for the CPiA PPC2 driven parallel connected
Camera. For example the Creative WebcamII is CPiA driven.
) [1]Peter Pregler, Linz 2000, published under the [2]GNU GPL
---------------------------------------------------------------------------
USAGE:
General:
========
1) Make sure you have created the video devices (/dev/video*):
- if you have a recent MAKEDEV do a 'cd /dev;./MAKEDEV video'
- otherwise do a:
cd /dev
mknod video0 c 81 0
ln -s video0 video
2) Compile the kernel (see below for the list of options to use),
configure your parport and reboot.
3) If all worked well you should get messages similar
to the following (your versions may be different) on the console:
V4L-Driver for Vision CPiA based cameras v0.7.4
parport0: read2 timeout.
parport0: Multimedia device, VLSI Vision Ltd PPC2
Parallel port driver for Vision CPiA based camera
CPIA Version: 1.20 (2.0)
CPIA PnP-ID: 0553:0002:0100
VP-Version: 1.0 0100
1 camera(s) found
As modules:
===========
Make sure you have selected the following kernel options (you can
select all stuff as modules):
The cpia-stuff is in the section 'Character devices -> Video For Linux'.
CONFIG_PARPORT=m
CONFIG_PARPORT_PC=m
CONFIG_PARPORT_PC_FIFO=y
CONFIG_PARPORT_1284=y
CONFIG_VIDEO_DEV=m
CONFIG_VIDEO_CPIA=m
CONFIG_VIDEO_CPIA_PP=m
For autoloading of all those modules you need to tell module-init-tools
some stuff. Add the following line to your module-init-tools config-file
(e.g. /etc/modprobe.conf or wherever your distribution does store that
stuff):
options parport_pc io=0x378 irq=7 dma=3
alias char-major-81 cpia_pp
The first line tells the dma/irq channels to use. Those _must_ match
the settings of your BIOS. Do NOT simply use the values above. See
Documentation/parport.txt for more information about this. The second
line associates the video-device file with the driver. Of cause you
can also load the modules once upon boot (usually done in /etc/modules).
Linked into the kernel:
=======================
Make sure you have selected the following kernel options. Note that
you cannot compile the parport-stuff as modules and the cpia-driver
statically (the other way round is okay though).
The cpia-stuff is in the section 'Character devices -> Video For Linux'.
CONFIG_PARPORT=y
CONFIG_PARPORT_PC=y
CONFIG_PARPORT_PC_FIFO=y
CONFIG_PARPORT_1284=y
CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_CPIA=y
CONFIG_VIDEO_CPIA_PP=y
To use DMA/irq you will need to tell the kernel upon boot time the
hardware configuration of the parport. You can give the boot-parameter
at the LILO-prompt or specify it in lilo.conf. I use the following
append-line in lilo.conf:
append="parport=0x378,7,3"
See Documentation/parport.txt for more information about the
configuration of the parport and the values given above. Do not simply
use the values given above.
---------------------------------------------------------------------------
FEATURES:
- mmap/read v4l-interface (but no overlay)
- image formats: CIF/QCIF, SIF/QSIF, various others used by isabel;
note: all sizes except CIF/QCIF are implemented by clipping, i.e.
pixels are not uploaded from the camera
- palettes: VIDEO_PALETTE_GRAY, VIDEO_PALETTE_RGB565, VIDEO_PALETTE_RGB555,
VIDEO_PALETTE_RGB24, VIDEO_PALETTE_RGB32, VIDEO_PALETTE_YUYV,
VIDEO_PALETTE_UYVY, VIDEO_PALETTE_YUV422
- state information (color balance, exposure, ...) is preserved between
device opens
- complete control over camera via proc-interface (_all_ camera settings are
supported), there is also a python-gtk application available for this [3]
- works under SMP (but the driver is completely serialized and synchronous)
so you get no benefit from SMP, but at least it does not crash your box
- might work for non-Intel architecture, let us know about this
---------------------------------------------------------------------------
TESTED APPLICATIONS:
- a simple test application based on Xt is available at [3]
- another test-application based on gqcam-0.4 (uses GTK)
- gqcam-0.6 should work
- xawtv-3.x (also the webcam software)
- xawtv-2.46
- w3cam (cgi-interface and vidcat, e.g. you may try out 'vidcat |xv
-maxpect -root -quit +noresetroot -rmode 5 -')
- vic, the MBONE video conferencing tool (version 2.8ucl4-1)
- isabel 3R4beta (barely working, but AFAICT all the problems are on
their side)
- camserv-0.40
See [3] for pointers to v4l-applications.
---------------------------------------------------------------------------
KNOWN PROBLEMS:
- some applications do not handle the image format correctly, you will
see strange horizontal stripes instead of a nice picture -> make sure
your application does use a supported image size or queries the driver
for the actually used size (reason behind this: the camera cannot
provide any image format, so if size NxM is requested the driver will
use a format to the closest fitting N1xM1, the application should now
query for this granted size, most applications do not).
- all the todo ;)
- if there is not enough light and the picture is too dark try to
adjust the SetSensorFPS setting, automatic frame rate adjustment
has its price
- do not try out isabel 3R4beta (built 135), you will be disappointed
---------------------------------------------------------------------------
TODO:
- multiple camera support (struct camera or something) - This should work,
but hasn't been tested yet.
- architecture independence?
- SMP-safe asynchronous mmap interface
- nibble mode for old parport interfaces
- streaming capture, this should give a performance gain
---------------------------------------------------------------------------
IMPLEMENTATION NOTES:
The camera can act in two modes, streaming or grabbing. Right now a
polling grab-scheme is used. Maybe interrupt driven streaming will be
used for a asynchronous mmap interface in the next major release of the
driver. This might give a better frame rate.

4. Programming interface
This driver conforms to video4linux and video4linux2, both can be used to
use the driver. Since video4linux didn't provide adequate calls to fully
use the cards' features, we've introduced several programming extensions,
which are currently officially accepted in the 2.4.x branch of the kernel.
These extensions are known as the v4l/mjpeg extensions. See zoran.h for
details (structs/ioctls).

More information on the video4linux/mjpeg extensions, by Serguei
Miridonovi and Rainer Johanni:
--
The ioctls for that interface are as follows:
BUZIOC_G_PARAMS
BUZIOC_S_PARAMS
Get and set the parameters of the buz. The user should always do a
BUZIOC_G_PARAMS (with a struct buz_params) to obtain the default
settings, change what he likes and then make a BUZIOC_S_PARAMS call.
BUZIOC_REQBUFS
Before being able to capture/playback, the user has to request
the buffers he is wanting to use. Fill the structure
zoran_requestbuffers with the size (recommended: 256*1024) and
the number (recommended 32 up to 256). There are no such restrictions
as for the Video for Linux buffers, you should LEAVE SUFFICIENT
MEMORY for your system however, else strange things will happen ....
On return, the zoran_requestbuffers structure contains number and
size of the actually allocated buffers.
You should use these numbers for doing a mmap of the buffers
into the user space.
The BUZIOC_REQBUFS ioctl also makes it happen, that the next mmap
maps the MJPEG buffer instead of the V4L buffers.
BUZIOC_QBUF_CAPT
BUZIOC_QBUF_PLAY
Queue a buffer for capture or playback. The first call also starts
streaming capture. When streaming capture is going on, you may
only queue further buffers or issue syncs until streaming
capture is switched off again with a argument of -1 to
a BUZIOC_QBUF_CAPT/BUZIOC_QBUF_PLAY ioctl.
BUZIOC_SYNC
Issue this ioctl when all buffers are queued. This ioctl will
block until the first buffer becomes free for saving its
data to disk (after BUZIOC_QBUF_CAPT) or for reuse (after BUZIOC_QBUF_PLAY).
BUZIOC_G_STATUS
Get the status of the input lines (video source connected/norm).
This driver conforms to video4linux2. Support for V4L1 and for the custom
zoran ioctls has been removed in kernel 2.6.38.
For programming example, please, look at lavrec.c and lavplay.c code in
lavtools-1.2p2 package (URL: http://www.cicese.mx/)
