This page is deprecated and no more supported. 

The purpose of this page is to describe the usage of Xilinx Linux V4L2 Mem 2 Mem Composite video Framework driver.

Overview

The Xilinx Linux V4L2 M2M Composite Video Framework (xilinx-m2m.c) represents the whole pipeline with multiple sub-devices between Xilinx read buffer and Xilinx write buffer devices. In the V4L2 framework it is a bridge driver. The pipeline can be configured through the media node(/dev/media*), and the control operations such as stream on/off can be performed through the video node(/dev/video*). 

The Xilinx Linux V4L2 M2M Composite Video Framework is designed to enable the creation of Xilinx Frame buffer read device and Frame buffer write device which move video frames from one memory buffer to another and multiple v4l2 sub-devices in between, performing some sort of transformation on the way.
