Welcome to the video4linux wiki (For DVB wiki, click here)

This wiki is designed to serve as a community focus and the resource of reference for users and developers of the Video4Linux framework. In the short term, the task is to document the operation and quirks of hardware supported by v4l applications, to complement and offload the v4l mailing list -- cf. searchable archives.

We are also encouraging developers to turn this site into a repository of knowledge about v4l, helping to ensure that expertise acquired through much hard labor and long dedication won't get lost, but can be passed on to new developers and keep free software thriving.

If you are a user looking for help, please try searching the mailing list archives first, before asking a question on the v4l mailing list. Don't leave your question on the wiki -- ask on the mailing list!

For immediate help, log on to the #v4l irc channel on irc.freenode.net a try (see the log) -- hopefully someone there will be able to help you!

The wiki will only be as useful as we make it. Every user of video4linux has something to contribute, and we encourage you to begin right away. Whatever you can contribute will be warmly appreciated, whether it is a set of instructions for how to get a certain card working, a report on the audio and video quality of a working card, suggestions for how to extend an existing driver or write a new one, or an explanation of the internal logic of v4l itself.

To keep these instructions free, all contributions to this wiki are automatically licensed under the GNU General Public License GPL. If you wish, you may specify in each case that your contribution is dual-licensed under the MIT License. Please help us keep spam away by signing in before you post.

Enjoy!

People behind V4L


To make a contribution, please begin by familiarizing yourself with the layout of the site, so that your contribution will end up in the right location. As the site grows, it takes increasing discipline to keep it from turning into a tangle. We want to aggregate information about available hardware, v4l experiences, HOWTOs, and technical information about the workings of v4l devices work, and it's up to each of us to do this in a way that makes the information easy to access -- a useful and well-organized resource for everyone interested in video4linux.
