IAsyncReader::SyncReadAligned
Performs a synchronous read of the data.
HRESULT SyncReadAligned(
IMediaSample *pSample);
Parameters
- pSample
Sample to read.
Return Values
Returns an HRESULT value that depends on the implementation of the interface. Current DirectShow implementation return values include:
Value | Description |
---|---|
VFW_E_BADALIGN | An invalid alignment was specified. |
HRESULT_FROM_WIN32 | Win32 error. |
S_FALSE | Size changed (probably due to end of file). |
S_OK | Success. |
Remarks
The sample passed in must have been acquired from the agreed allocator. The start and stop positions must be aligned equivalent to an IAsyncReader::Request/IAsyncReader::WaitForNext pair, but may avoid the need for a thread on the source filter.
