IMFSourceReaderCallback interface (mfreadwrite.h)
Callback interface for the Microsoft Media Foundation source reader.
Inheritance
The IMFSourceReaderCallback interface inherits from the IUnknown interface. IMFSourceReaderCallback also has these types of members:
Methods
The IMFSourceReaderCallback interface has these methods.
| IMFSourceReaderCallback::OnEvent Called when the source reader receives certain events from the media source. |
| IMFSourceReaderCallback::OnFlush Called when the IMFSourceReader::Flush method completes. |
| IMFSourceReaderCallback::OnReadSample Called when the IMFSourceReader::ReadSample method completes. |
Remarks
Use the MF_SOURCE_READER_ASYNC_CALLBACK attribute to set the callback pointer when you first create the source reader object.
The callback methods can be called from any thread, so an object that implements this interface must be thread-safe.
If you do not specify a callback pointer, the source reader operates synchronously.
This interface is available on Windows Vista if Platform Update Supplement for Windows Vista is installed.
