* 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
