CaptureFileOutput class abstract
The abstract superclass for capture outputs that can record captured data to a file.
This abstract superclass defines the interface for outputs that record media samples to files. File outputs can start recording to a new file using the startRecordingToOutputFileURL method. On successive invocations of this method on Mac OS X, the output file can by changed dynamically without losing media samples. A file output can stop recording using the stopRecording method. Because files are recorded in the background, applications will need to specify a delegate for each new file so that they can be notified when recorded files are finished.
On Mac OS X, clients can also set a delegate on the file output itself that
can be used to control recording along exact media sample boundaries using
the CaptureFileOutputDelegate.captureOutput method.
The concrete subclasses of CaptureFileOutput are CaptureMovieFileOutput,
which records media to a QuickTime movie file, and CaptureAudioFileOutput,
which writes audio media to a variety of audio file formats.
