Each project has a short description and an indication of the difficulty and guesstimated time in days (assume around 7-8 hours per day). Projects marked 'Beginner' are suitable for those with little experience with C and kernel development. Projects marked 'Medium' require C experience and at least some knowledge about kernel driver development. Projects marked 'Hard' require a solid amount of kernel development experience and ideally at least some knowledge about media subsystem development.

This page lists open source projects related to the V4L2 subsystem that are in need of volunteers.

Each project has a short description and an indication of the difficulty and guesstimated time in days (assume around 7-8 hours per day). Projects marked 'Easy' are suitable for those with little experience with C and kernel development. Projects marked 'Medium' require C experience and at least some knowledge about kernel driver development. Projects marked 'Hard' require a solid amount of kernel development experience and ideally at least some knowledge about media subsystem development.

If you are interested in one of these projects, then please contact the linux-media mailinglist.

  • VIMC: Add HDMI emulation support. The vimc (Virtual Media Controller) driver supports sensors, but it does not have a sub-device driver for HDMI receivers. It would be nice to have this for prototyping purposes. Difficulty: medium. Time: 10 days.
  • VIMC: Add S-Video emulation support. The vimc (Virtual Media Controller) driver supports sensors, but it does not have a sub-device driver for S-Video receivers. It would be nice to have this for prototyping purposes. Difficulty: medium. Time: 10 days.
  • VIMC: Add frame rate control. The vimc (Virtual Media Controller) driver support different frame resolutions, but it does not support different frame rates. Add support for this. Difficulty: Easy/Medium. Time: 5 days.
  • VIMC: Add support for cropping/composing. The vimc (Virtual Media Controller) driver does not have any support for the cropping and composing API (aka selection API). Add support for this. Difficulty: Medium. Time: 10-15 days.
  • V4L2 Documentation: the Extended Controls documentation should be split up into sub-sections, one for each class of controls. Difficulty: Easy. Time: 1 day.
  • V4L2 Documentation: re-organize the Selection API documentation. It's messy and the information is spread over too many pages. Difficulty: Easy/Medium. Time: 2-4 days.
