* #27232: jni: added pjproject checkout as regular git content
We will remove it once the next release of pjsip (with Android support)
comes out and is merged into SFLphone.

+ * @brief Video communication via the network
+ * @{
+ *
+ * A video stream is a bidirectional video communication between two
+ * endpoints. It corresponds to a video media description ("m=video" line)
+ * in SDP session descriptor.
+ *
+ * A video stream consists of two unidirectional channels:
+ * - encoding channel, which transmits unidirectional video to remote, and
+ * - decoding channel, which receives unidirectional media from remote.
+ *
+ * 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
+ * direction),
+ * - 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(),
+ * specifying #pjmedia_stream_info structure in the parameter. Application
+ * can construct the #pjmedia_vid_stream_info structure manually, or use
+ * #pjmedia_vid_stream_info_from_sdp() function to construct the
+ * #pjmedia_vid stream_info from local and remote SDP session descriptors.
