Development: Linux Media Infrastructure API
The Linux Media Infrastructure API provides a common body of knowledge for kernel to userspace application programming interfaces used by media drivers. It converges two historically separate API, namely the Video for Linux (V4l) API and the Linux Digital Video Broadcasting (Linux DVB) API, plus adds the IR input event mapping API.
It is released with each new kernel revision. The latest version is 2.6.32 released 31 August 2009 and is available here
The original V4L and DVB API specs are still available as separate documents. However, only the Linux Media Infrastructure API will be updated.
