Free video4linux devices software for linux

Mach64 video4linux2 is a video4linux device driver for older Mach64 TV tuner cards.
Mach64 video4linux2 is very alpha, and has only been tested with a few cards: a 4 MB All-in-wonder capture card, a 2 MB ATI Rage II+ with an ISA add-on TV card, and an ATI Rage Pro video card with an ISA add-on TV card.
There are versions for 2.6.* and 2.4.* kernels.
Module Options:
debug (set the debug level)
disablev4l2 (disable all v4l2 functions)
disabledma (disable dma support)
disableinterlace (max resolution will be 640x240)
Note: when the height is less than or equal to 240 interlace is automatically turned off. (probably a bad idea but it makes better snapshots in xawtv that way)
halfwidth (cut max width in half 640 becomes 320)
forceromaddr (Force romaddr to 0x000C0000)
tunertype (0=pal, 1=ntsc, 2=secam, 3=pal nc, 4=pal m, 5= pal n, 6=ntsc jp) it will default to ntsc(1)
Example commands:
MPlayer 1.0
mplayer tv://50 -tv driver=v4l:input=1:norm=ntsc:outfmt=yuy2:width=320:height=240:chanlist=us-cable -nofs
MPlayer 0.92
mplayer -tv on:driver=v4l:input=1:norm=ntsc:outfmt=yuy2:width=320:height=240:chanlist=us-cable:channel=50 -nofs
FFmpeg (you need an external program to change the channel)
ffmpeg -vd /dev/video0 -ad /dev/dsp -r 29.97 -s 320x240 -acodec mp3 /tmp/test.avi
Notes:
Make sure your card has an irq assigned to it (there is a jumper on most cards that can enable/disable this)
If you have multiple video cards and the ATI card is not set as the primary card, you cannot load the module until X has enabled it. (Using kmod would be a good idea, it loads modules when you access the device)
Make sure you load the videodev module as well!
Whats missing
Support for other ATI cards (should be able to support anything the GATOS driver supports)
Audio chip stuff (volume, bass, treble for cards with audio chips) etc etc etc...
Known bugs
Can only capture from one card at a time. (hangs if you use more than one)
If your using kernel 2.4.* and it segfaults, the first thing you should do is update the video4linux header files videodev.h and videodev2.h you can get them from here http://bytesex.org/patches/
Does not work with mach64 DRI, my dma code assumes it has complete control.
Enhancements:
- This release adds DMA support for AMD-64 machines.

Linux X10 universal device driver (also known as Project WiSH) provides a /dev interface to an X10 network through a combination of Linux kernel modules and daemons.
It is intended to provide a standard interface and syntax to shell script utilities (such as cat and echo), Perl scripts, C programs, or Java programs so that everything from a quick hack to a more advanced program can manipulate the X10 devices in an automated home regardless of the transceiver used.
Its simplest use is with shell scripts (examples of which are provided in the package). Currently the project supports the 3 X10 transceivers (PowerLinc Serial, PowerLinc USB, and CM11A).
Main features:
- Full /dev/x10 capability with enhancements for non-blocking writes
- Full support for PowerLinc Serial transceiver
- Full support for CM11A Serial transceiver
- Full support for PowerLinc USB transceiver (with kernel patches for USB)
Enhancements:
- X10 state machine simulator runs in userspace
- Kernel module maintains status of individual devices and implements API only
- non-blocking writes (by popular demand) so commands can be queued up in rapid succession
- PowerLinc USB now uses HID interface
- Version 2.0 drivers work with kernel 2.6.7 and higher and with kernel version 2.4.0 (the PowerLinc USB will not work with kernel 2.4 due to lack of support for multibyte messages in the USB subsystem of the kernel. If you require the PowerLinc USB and kernel 2.4, use wish-1.6.10. )
- Simpler compilation and installation method

Portable SDK for UPnP Devices in short libupnp provides developers with an API and code for building control points, devices, and bridges that are compliant with Version 1.0 of the Universal Plug and Play Device Architecture Specification.
This allows discovery, event notification, and control of devices on a network, independent of operating system, programming language, or physical network connection.
UPnP is an architecture that enables discovery, event notification, and control of devices on a network, independent of operating system, programming language, or physical network connection. UPnP is based on common Internet standards and specifications such as TCP/IP, HTTP, and XML.
Enhancements:
- Full support for the Windows and FreeBSD operating systems was added.
- Fixes were made for x86_64 architectures.
- Several memory leaks and possible reasons for crashes were fixed.

VideoDog software was a kind of video /bin/cat, to grab a single frame of a video4linux device or set some pictures default.

Now it evolved into a complete image capture/processing environment, with a simple and clean API, and using almost no external libs.

It works with linuxs v4l subsystem, has a lot of algorithms for image processing and storage, including motion detection, alpha blending logos, image formats, edge detection, and so on. Also, it includes examples on how to deal with jpeglib, gtk, SDL and XLib, regarding image capture and processing.

You can use a simple config file, suited for the most common needs, or use the command line options.

To change the path, just edit the makefile. The default path is /etc/vd.conf.
In the folder called "extra" you will find the gtkpnm, xputjpeg, gtk_cam and a small swap asm function, bgr2rgb.

There is a man page. Just check it with man ./videodog.man or move to a proper location. Its not complete yet, so, I didn`t put it in the Makefile.

*In a short:*

Just grabs a frame from v4l device or set its picture defaults. Useful for scripts, webcam scripts. No dependencies of any external libs.

This code is GPLed, feel free to use it and send me tips, patches,etc, etc.

Please, send me bug reports, feedbacks, ideas, patches and stuffs.

Possible outputs:

RAW frame (RGB)
PNM frame
JPEG frame
TARGA24 (tga) frame.
Double buffer loop capture or single frame with any format.

Tested with:

CPiA driver (webcam II parport)
Bttv driver ( bt 848 & 878 )
ov511 ( webcam III usb )
DLINK cam

PulseAudio Device Chooser (padevchooser) is a simple GTK tool which registers an icon in the tray area and allows quick access to some features of the PulseAudio sound server.
Main features:
Notify about new sink/sources becoming available on the LAN;
Quickly change the default PulseAudio sink/source/server assigned to the current X11 display, selecting devices available on the LAN;
Start the auxiliary tools PulseAudio Volume Control, PulseAudio Volume Meter, PulseAudio Manager

Device::Serdisp is a Perl extension for talking to the serdisplib.

SYNOPSIS

use Device::Serdisp;

my $d = Device::Serdisp->new(USB:7c0/1501, ctinclud);
$d->init();
$d->clear();

# reserves a color-indexed picture
my $image = GD::Image->new(128,64);
my $black = $image->colorAllocate(0,0,0);
my $white = $image->colorAllocate(255,255,255);

$image->transparent($black);
$image->arc(10,10,10,10,0,270, $white);
$d->copyGD($image);

mod_video was created in order for me to be able to check on my apartment while on holiday using a camcorder hooked up to my Linux machine. It it an Apache module.

A few months earlier I had picked up a BTTV-based (Bt848) frame grabber card from the leftovers bin, and although I was able to make it work I cant say that it was very impressive.

The software that came with it just locked up my machine under Windows, and the software available under Linux wasnt too hot either. The image quality can at best be described as questionable.

The module was written the night before I was leaving for my holiday, and being the first time I had used the video4linux API, I had to pick apart a few programs written by other people in order to figure out how to make things work. The documentation I was able to find on the net didnt really answer all my questions and at times it was just confusing.

I hadnt written anything that encodes JPG or PNG images before either, so I had to figure out how libpng and libjpeg work as well. Hopefully I didnt screw up too badly.
