Constructor.
| TInt aMaxBlocksPerRequest | Maximum number of blocks that can be sent from the stream to client in a single request. |
| const TSize & aMinBlockSizeInPixels | Minimum size in pixels of a block sent to the stream from the client in a single request. |
| TInt aOptimalBlocksPerRequest | Optimum number of blocks sent to the stream from the client in a single request to get maximum performance benefit. |
| TEncodeStreamCaps::TNavigation aNavigation | Navigation capabilities. |

navigation capabilities.
Full random access to the stream if Navigation() returns ENavigationSequentialForward | ENavigationRandomForward |ENavigationRandomBackwards
| IMPORT_C TInt | OptimalBlocksPerRequest | ( | ) | const |
Optimum number of blocks sent to the stream from the client in a single request to get maximum performance benefit.
Optimum number of blocks sent to the stream from the client in a single request to get maximum performance benefit.
Navigation possibilities within the stream.
| ENavigationSequentialForward = 0x01 |
Blocks can be returned from first to last |
| ENavigationRandomForward = 0x02 |
Blocks can be returned in a random order but moving only from first to last e.g. 1, 5, 18... |
| ENavigationRandomBackwards = 0x04 |
Blocks can be returned in a random order but moving only from last to first e.g. 1, 5, 18... |
