libv4l2cpp
====================

It is a C++ wrapper for V4L2

Dependencies
------------
 - liblog4cpp5-dev (optional)
 
V4L2 Capture
-------------
 - create a V4L2 Capture interface using MMAP interface:

V4L2DeviceParameters param("/dev/video0", V4L2_PIX_FMT_*, width, height, fps, IOTYPE_MMAP);
         V4l2Capture* videoCapture = V4l2Capture::create(param);

- data are available :

timeval timeout; 
         bool isReadable = videoCapture->isReadable(&timeout);

- read data :

size_t nb = videoCapture->read(buffer, bufferSize);

V4L2 Output
-------------

- To create a V4L2 Output interface using MMAP interface:

V4L2DeviceParameters param("/dev/video0", V4L2_PIX_FMT_*, width, height, fps, IOTYPE_MMAP);
         V4l2Output* videoOutput = V4l2Output::create(param);

- data could be written :

timeval timeout; 
         bool isWritable = videoOutput->isWritable(&timeout);

- write data :

size_t nb = videoOutput->write(buffer, bufferSize);
