|
96 The class offers a simple interface to record and set meta data and control information for a video |
|
97 clip and save the result to a file, descriptor or URL. |
|
98 |
|
99 Note: |
|
100 Some video formats also allow the storing of audio data. To accommodate this, this class contains |
|
101 audio functions that can manipulate such data. |
|
102 |
|
103 While this class is abstract, NewL() constructs, initialises and returns pointers to instances of |
|
104 concrete classes derived from this abstract class. This concrete class is part of the MMF |
|
105 implementation and is private. |
