-* 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
