v4l2loopback

this is v4l2 loopback device which output is it's own input. this is useful for feeding different v4l2 applications with video from non v4l2 sources, for example one can feed Skype with video enhanced by gstreamer effects; or use input device which does not have v4l2 compliant driver. code ... [More] is based on avld driver, but in fact it is a complete rewrite and final version unlikely will share common code. [Less]

V4l2capture

V4l2capture is a CLI software to grab images from a v4l2 image device.

V4LCtrl

V4LCtrl is simple utility for show and set controls of V4L devices like brightness, saturation, gama, rotation... It contains two variants. With simple GUI (based on QT4) and command line interface, that is powerful for diagnostics or scripting.

python-video4linux2

Summary says it all. I've been trying to find an existing project for python to video4linux2 coding, but no one else seems to have released any files to download yet, so here we are! You'll need SVN in order to check out my current implementation. Documentation is not provided at this ... [More] point, but the main file contains device information checks by running it (python pyv4l2.py), and check out the recordpics.py for a sample program to save JPEG images from a particular device and input such as cd python-video4linux make ./pyv4l2.py ./streampics.py /dev/video0 0 BGR3 640 480 testpicsThe next things which I would like to do with the library is to add video saving support using libtheora. The latter will probably be its own extension named python-theora. I definitely need help with distutils, internationalization, and performance patches if anyone would wish to help. The current version does about 27.5fps on my Happugage ImpactVCB test card with the mmap interface, which is almost that of the NTSC standard at 29.97 fps. Note: JPEG saving functionality requires the python imaging library (emerge -av imaging for us Gentoo users 8-) [Less]

pygame-camera

This project is a Google Summer of Code (GSoC) 2008 project for One Laptop Per Child (OLPC), to create a computer vision library for use in Activities on the laptop. This library is taking the form of a module or modules added to pygame. Currently, the module supports v4l2 cameras and outputs ... [More] images as pygame Surfaces in RGB, YUV, and HSV colorspaces. [Less]

camera-cat

This program is a camera cat program , current support to type of output , 1. a lot of jpeg images, with continue name, 2. a file of yuv422 vyuy format you can you this file to learn V4L2 API programming or just ues as a test suit. have fun!

blintv

it's just my experiment in gnome and v4l2 for now.

tp68xx-webcam-drv

Linux kernel driver for TOPRO's line of USB webcam controller chips.I should imagine there are numerous manufacturers that use this webcam controller. My webcam is an unbranded one originally from ebuyer sold as a "USB 2.0 Media Kit" which actually consists of: a powered USB 2.0 ... [More] hub (already supported by linux), with embedded C-Media-based (Vend: 0x0d8c, Prod: 0x000c) stereo audio out and microphone in (already supported by linux), with a moulded USB socket in the top of the hub base for the supplied USB 1.1 TP6801-based webcam (Vend: 0x06a2, Prod: 0x0003). The webcam is the typical spherical type on a bendy stem with manual focussing ring on the lens. History Date Version Description 2009-Feb Initial Draft Created initial draft - untested and unusable [Less]

lpantilt

This is a module for interfacing with the v4l2 pan and tilt controls - as used on the logitech sphere webcams - using python. This module uses cython and ioctl to inject commands. The original goal was to have a commandline interface to pan and tilt in x,y steps and z speed. This will be very easy to create once we have a usable library.

python-v4l2

Object Oriented Python Video4Linux 2 library. Provides easy access to video, radio and vbi devices in python.
