IMFSourceReaderCallback interface

Callback interface for the Microsoft Media Foundation source reader.

Methods

The IMFSourceReaderCallback interface has these methods.

Method Description
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.
