/*****************************************************************************<br />
* How to use it<br />
*****************************************************************************<br />
*<br />
* You should use this module in combination with the transcode module, to get<br />
* raw datas from it. This module does not make any conversion at all, so you<br />
* need to use the transcode module for this purpose.<br />
*<br />
* For example, you can use smem as it :<br />
* --sout="#transcode{vcodec=RV24,acodec=s16l}:smem{smem-options}"<br />
*<br />
* Into each lock function (audio and video), you will have all the information<br />
* you need to allocate a buffer, so that this module will copy data in it.<br />
*<br />
* the video-data and audio-data pointers will be passed to lock/unlock function<br />
*<br />
