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