+ * @{
+
+PJMEDIA Video Device API is a cross-platform video API appropriate for use with
+VoIP applications and many other types of video streaming applications. 
+
+The API abstracts many different video API's on various platforms, such as:
+ - native Direct Show video for Win32 and Windows Mobile devices
+ - null-video implementation
+ - and more to be implemented in the future
+
+The Video Device API/library is an evolution from PJMEDIA @ref PJMED_SND and 
+contains many enhancements:
+
+ - Forward compatibility:
+\n
+   The new API has been designed to be extensible, it will support new API's as 
+   well as new features that may be introduced in the future without breaking 
+   compatibility with applications that use this API as well as compatibility 
+   with existing device implementations. 
+
+ - Device capabilities:
+\n
+   At the heart of the API is device capabilities management, where all possible
+   video capabilities of video devices should be able to be handled in a generic
+   manner. With this framework, new capabilities that may be discovered in the 
+   future can be handled in manner without breaking existing applications. 
+
+ - Built-in features:
+\n
+   The device capabilities framework enables applications to use and control 
+   video features built-in in the device, such as:
+    - built-in formats, 
+    - etc.
+
+ - Codec support:
+\n
+   Some video devices support built-in hardware video codecs, and application
+   can use the video device in encoded mode to make use of these hardware 
+   codecs. 
+
+ - Multiple backends:
+\n
+   The new API supports multiple video backends (called factories or drivers in 
+   the code) to be active simultaneously, and video backends may be added or 
+   removed during run-time.

+ * @brief Standard PJMEDIA object signatures
+ * @{
+ *
+ * Object signature is a 32-bit integral value similar to FOURCC to help
+ * identify PJMEDIA objects such as media ports, transports, codecs, etc.
+ * There are several uses of this signature, for example a media port can
+ * use the port object signature to verify that the given port instance
+ * is the one that it created, and a receiver of \ref PJMEDIA_EVENT can
+ * use the signature of the publisher to know which object emitted the
+ * event.
+ *
+ * The 32-bit value of an object signature is generated by the following
+ * macro:
+ *
+ * \verbatim
+   #define PJMEDIA_SIGNATURE(a,b,c,d)	(a<<24 | b<<16 | c<<8 | d)
+ * \endverbatim
+ *
+ * The following convention is used to maintain order to the signature
+ * values so that application can make use of it more effectively, and to
+ * avoid conflict between the values themselves. For each object type or
+ * class, a specific prefix will be assigned as signature, and a macro
+ * is created to build a signature for such object:
+ *
+ * \verbatim

+ * A video stream exports two media port interface (see @ref PJMEDIA_PORT),
+ * one for each direction, and application normally uses this interface to
+ * interconnect the stream to other PJMEDIA components, e.g: the video
+ * capture port supplies frames to the encoding port and video renderer
+ * consumes frames from the decoding port.
+ *
+ * A video stream internally manages the following objects:
+ *  - an instance of video codec (see @ref PJMEDIA_VID_CODEC),
+ *  - an @ref PJMED_JBUF,
+ *  - two instances of RTP sessions (#pjmedia_rtp_session, one for each

+ *  - one instance of RTCP session (#pjmedia_rtcp_session),
+ *  - and a reference to video transport to send and receive packets
+ *    to/from the network (see @ref PJMEDIA_TRANSPORT).
+ *
+ * Video streams are created by calling #pjmedia_vid_stream_create(),
