Public Member Functions | |
| virtual TDesC8 * | DataL (TInt aIndex)=0 |
| Gets a non-bitmap frame in the buffer. | |
| virtual CFbsBitmap * | FrameL (TInt aIndex)=0 |
| Gets a bitmap frame in the buffer. | |
| virtual void | Release ()=0 |
| Releases the buffer for re-use by the camera once the client has processed the frame data. | |
Public Attributes | |
| TInt | iIndexOfFirstFrameInBuffer |
| Sequential frame number of the first frame in the buffer, counting from when CCamera::StartVideoCapture() was called and including frames dropped due to lack of buffers. | |
| TTimeIntervalMicroSeconds | iElapsedTime |
| Time elapsed from when CCamera::StartVideoCapture() was called until the first frame in the buffer was captured. | |
Buffer class for passing video frames between camera and client.
May contain multiple frames.
|
pure virtual |
Gets a non-bitmap frame in the buffer.
| aIndex | The index of the required, non-bitmap, frame. |
Leave condition: KErrArgument if aIndex is out of range Leave condition: KErrNotSupported if the frame format is bitmap.
|
pure virtual |
Gets a bitmap frame in the buffer.
| aIndex | The index of the required, bitmap format, frame. |
Leave condition: KErrArgument if aIndex is out of range and Leave condition: KErrNotSupported if the frame format is not a bitmap.
|
pure virtual |
Releases the buffer for re-use by the camera once the client has processed the frame data.
Signals to CCamera that the buffer data has been used and that the buffer is free for re-use.
| TTimeIntervalMicroSeconds MFrameBuffer::iElapsedTime |
Time elapsed from when CCamera::StartVideoCapture() was called until the first frame in the buffer was captured.
| TInt MFrameBuffer::iIndexOfFirstFrameInBuffer |
Sequential frame number of the first frame in the buffer, counting from when CCamera::StartVideoCapture() was called and including frames dropped due to lack of buffers.
