FTP site for sample drivers. Configure Video for Linux as a module, and rebuild kernel and kernel modules if necessary. There is a sample capture program, xcaptest.c, which exercises the capture functions of a V4L2 driver, and a video control panel program, vidpanel.c, that exercises the brightness, contrast, etc. These require X Windows. In addition, command line programs vcat and vctrl programs are for capturing frames, and setting device parameters are included.
All applications work with the sample capture driver.
FTP site for sample applications. An excellent source of help for general Video for Linux issues is the video4linux mail list . If you would like to contribute to the V4L2 project, or have any questions about the API or software supporting it, send me an email.
