CVideoRecorderUtility Class Reference

class CVideoRecorderUtility : public CBase

Records video data.

The class offers a simple interface to record and set meta data and control information for a video clip and save the result to a file, descriptor or URL.

Note: Some video formats also allow the storing of audio data. To accommodate this, this class contains audio functions that can manipulate such data.

While this class is abstract, NewL() constructs, initialises and returns pointers to instances of concrete classes derived from this abstract class. This concrete class is part of the MMF implementation and is private.
