IMemInputPin::ReceiveMultiple (Windows Embedded CE 6.0)
1/6/2010
This method returns the next block of data from the stream.
This method behaves much like the IMemInputPin::Receive method, but it works with multiple samples.
Syntax
HRESULT ReceiveMultiple(
IMediaSample** pSamples,
long nSamples,
long* nSamplesProcessed
);
Parameters
- pSamples
[in] Pointer to an array of samples.
- nSamples
[in] Number of samples to process.
- nSamplesProcessed
[out] Number of samples processed.
Return Value
Returns an HRESULT value that depends on the implementation.
HRESULT can be one of the following standard constants, or other values not listed.
| Value | Description |
|---|---|
E_FAIL |
Failure. |
E_POINTER |
Null pointer argument. |
E_INVALIDARG |
Invalid argument. |
E_NOTIMPL |
Method is not supported. |
S_OK or NOERROR |
Success. |
Remarks
This method allows a connected output pin to deliver multiple samples at one time.
Use it if, like COutputQueue, the output pin batches samples for delivery together.
Implement this if your filter can handle batched samples more efficiently than individual samples.
The base class implementation of this method calls IMemInputPin::Receive repeatedly. Override this implementation if you can do something more efficiently in your derived class.
Requirements
