Description copied from interface: MediaFormat (src)

Extracts a media header instance from the given media content and returns it. The information presented by the header is up to the implementation of the media format bean, and the information returned can therefore be the complete header information as defined in the relevant media format standard, no information at all, or something in between. However, implementers are encouraged to return header information as complete as possible, as such information can be highly useful for format specific algorithms and optimizations.

Please note that the given input stream is not closed once the operation is successfully completed.
