+/**
+ * Set callbacks and private data to render decoded video to a custom area
+ * in memory. Use libvlc_video_set_format() to configure the decoded format.
+ *
+ * Whenever a new video frame needs to be decoded, the lock callback is
+ * invoked. Depending on the video chroma, one or three pixel planes of
+ * adequate dimensions must be returned via the second parameter. Those
+ * planes must be aligned on 32-bytes boundaries.
+ *
+ * When the video frame is decoded, the unlock callback is invoked. The
+ * second parameter to the callback corresponds is the return value of the
+ * lock callback. The third parameter conveys the pixel planes for convenience.
+ *
+ * When the video frame needs to be shown, as determined by the media playback
+ * clock, the display callback is invoked. The second parameter also conveys
+ * the return value from the lock callback.
+ *
+ * \param mp the media player
+ * \param lock callback to allocate video memory
+ * \param unlock callback to release video memory
+ * \param opaque private pointer for the three callbacks (as first parameter)
+ * \version LibVLC 1.1.1 or later
