CMMFVideoPreProcHwDevice Class Reference
| class CMMFVideoPreProcHwDevice : public CMMFVideoRecordHwDevice |
CMMFVideoPreProcHwDevice is the MSL video pre-processor plug-in interface. All MSL video pre-processors must implement this interface.

Member Functions Documentation
NewL(TUid, MMMFDevVideoRecordProxy &)
Creates a new video pre-processor hardware device object, based on the implementation UID.
- leave
- "This method will leave if an error occurs."
ReturnPicture(TVideoPicture *)
Returns a used picture back to the pre-processor. Called by an encoder device when used as output device from a pre-processor.
- Pre-condition
- "This method can only be called after the hwdevice has been initialized with Initialize()."
SetOutputDevice(CMMFVideoEncodeHwDevice *)
Sets the video encoder device that will receive data from this pre-processor. Pre-processed pictures will be written with WritePictureL() or through a custom interface, and the encoder will return used pictures using ReturnPicture().
- Pre-condition
- "This method can only be called before the hwdevice has been initialized with Initialize()."
SetOutputFormatL(const TUncompressedVideoFormat &)
Sets the device output format. The picture size depends on the input data format and possible scaling performed.
-
leave
- " The method will leave if an error occurs. Typical error codes used:
- KErrNotSupported - The format specified is not supported."
- Pre-condition
- "This method can only be called before the hwdevice has been initialized with Initialize()."
SetProxy(MMMFDevVideoRecordProxy &)
Set the proxy implementation to be used. Called just after the object is constructed.
