38 * @class MediaStreamInfo
39 * @brief This class provides methods to get media stream information.
43 * The %MediaStreamInfo class provides methods to get media stream information, including:
44 * - %Content metadata, such as the title, artist, album title, genre, year, and album art.
45 * - Audio and video stream information.
47 * This class supports multiple stream content that consists of several audio or video tracks.
48 * This class provides a list of AudioStreamInfo and VideoStreamInfo that has the stream information of each audio or video track.
50 * For more detailed information, see %AudioStreamInfo and %VideoStreamInfo classes.
52 * The following example demonstrates how to use the %MediaStreamInfo class.
58 * using namespace Tizen::Base;
