/*
QTExtractAndConvertToMovie contains two Objective-C objects that are used together to
implement audio extraction and audio conversion from a QuickTime Movie's sound track to
an movie file.
The first is a simple class called MovieWriter (this is a modified version of the
AIFFWriter class that was included with the ExtractMovieAudioToAIFF and
QTExtractAndConvertToAIFF samples). MovieWriter uses QuickTime's Movie Audio Extraction,
Movie Storage and Media Creation APIs. The second is another simple class called
AudioConverter which encapsulates Core Audio's Audio Converter API.
The sample uses an instance of the MovieWriter class to easily set up audio extraction
from a QTKit QTMovie to a new destination Movie and its associated movie file (or movie
storage as it's called in the API). MovieWriter uses an instance of the AudioConverter
class to perform the conversion to a user selected destination format which is
configured by the Standard Audio Dialog Component. The Audio Converter uses a Movie
Audio Extraction Session in the Read Input Procedure to pull audio out of the source
Movie.
QTExtractAndConvertToMovie demonstrates how to call AddMediaSample2 and supports VBR as
well as CBR audio encoding formats.
NOTE: This sample uses the default extraction channel layout which is the aggregate
channel layout of the Movie (for example, all Rights mixed together, all Left Surrounds
mixed together, etc).
