4.2 TI-Provided V4L2 Drivers for Multimedia

Video4Linux version 2 (V4L2) is an open source framework that provides a media interface to all Linux-based applications. V4L2 is a collection of device drivers and an API for supporting real-time video capture and video memory-to-memory operations on Linux systems.

Video encode and decode using the encoder and decoder hardware, respectively, are enabled as V4L2 drivers. The V4L2 is integrated with the encoder and decoder drivers by a thin layer that implements the V4L2 node ioctls and translates the V4L2 data structures to those understood by the encoder/decoder.
