virtual void SetInputFormatL(const TUncompressedVideoFormat &aFormat)=0;
"This method can only be called before the hwdevice has been initialized with Initialize()."
Sets the device input format to an uncompressed video format.
|
|
virtual void SetInputDevice(CMMFVideoDecodeHwDevice *aDevice)=0;
"This method can only be called before the hwdevice has been initialized with Initialize()."
Sets the decoder device that will write data to this post-processor. Decoded pictures will be written with CMMFVideoPostProcHwDevice::WritePictureL(TVideoPicture *) or through a custom interface. After pictures have been processed, they must be returned to the decoder using CMMFVideoPlayHwDevice::ReturnPicture(TVideoPicture *).
|
virtual void WritePictureL(TVideoPicture *aPicture)=0;
"This method can only be called after the hwdevice has been initialized with Initialize()."
Writes an uncompressed video picture to the post-processor. The picture must be returned to the client or source plug-in after it has been used.
|
|
protected: virtual void SetProxy(MMMFDevVideoPlayProxy &aProxy)=0;
Set the proxy implementation to be used. Called just after the object is constructed.
