+* media-info is a library to collect metadata and streaminfo from media
+ files
+
+* the current implementation is idler-based.
+
+* you create a new media_info object
+* you set the string name of a source element to use using g_object_set or
+ gst_media_info_set_source
+* you declare you'll read a given file by using gst_media_info_read_with_idler
+* you loop gst_media_info_read_idler (info, &stream) as long as it returns TRUE
+ and as long as stream is still NULL
+
+
+* INTERNALS:
+ - instance_init sets up the media info reader, its elements, and connects
+ the deep_notify callback
+ - read_with_idler resets the media info reader object,
+ and sets location and flags
+
+ - read_idler runs through a state machine:
+ NULL - TYPEFIND - STREAM - METADATA - STREAMINFO - FORMAT
+
+ - NULL: just returns find_type_pre, which moves state to TYPEFIND
+ - TYPEFIND:
+ - iterates as long as it can until it has priv->type
+ - find_type_post
+ - call gmi_set_mime which creates a pipeline to decode stuff
+ - move to STREAM
+
+ - STREAM
