/**
* SECTION:element-typefind
+ * @title: typefind
*
* Determines the media-type of a stream. It applies typefind functions in the
- * order of their rank. One the type has been deteted it sets its src pad caps
+ * order of their rank. Once the type has been detected it sets its src pad caps
* to the found media type.
*
* Whenever a type is found the #GstTypeFindElement::have-type signal is
* 1) get a list of all typefind functions sorted best to worst
* 2) if all elements have been called with all requested data goto 8
* 3) call all functions once with all available data
- * 4) if a function returns a value >= PROP_MAXIMUM goto 8
+ * 4) if a function returns a value >= PROP_MAXIMUM goto 8 (never implemented))
* 5) all functions with a result > PROP_MINIMUM or functions that did not get
* all requested data (where peek returned NULL) stay in list
* 6) seek to requested offset of best function that still has open data
/* Require at least 2kB of data before we attempt typefinding in chain-mode.
* 128kB is massive overkill for the maximum, but doesn't do any harm */
