* 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
