Represents a byte stream from some data source, which might be a local file, a network file, or some other source. The IMFByteStream interface supports the typical stream operations, such as reading, writing, and seeking.
The IMFByteStream interface has these methods.
|IMFByteStream::BeginRead||Begins an asynchronous read operation from the stream.|
|IMFByteStream::BeginWrite||Begins an asynchronous write operation to the stream.|
|IMFByteStream::Close||Closes the stream and releases any resources associated with the stream, such as sockets or file handles. This method also cancels any pending asynchronous I/O requests.|
|IMFByteStream::EndRead||Completes an asynchronous read operation.|
|IMFByteStream::EndWrite||Completes an asynchronous write operation.|
|IMFByteStream::Flush||Clears any internal buffers used by the stream. If you are writing to the stream, the buffered data is written to the underlying file or device.|
|IMFByteStream::GetCapabilities||Retrieves the characteristics of the byte stream.|
|IMFByteStream::GetCurrentPosition||Retrieves the current read or write position in the stream.|
|IMFByteStream::GetLength||Retrieves the length of the stream.|
|IMFByteStream::IsEndOfStream||Queries whether the current position has reached the end of the stream.|
|IMFByteStream::Read||Reads data from the stream.|
|IMFByteStream::Seek||Moves the current position in the stream by a specified offset.|
|IMFByteStream::SetCurrentPosition||Sets the current read or write position.|
|IMFByteStream::SetLength||Sets the length of the stream.|
|IMFByteStream::Write||Writes data to the stream.|
The following functions return IMFByteStream pointers for local files:
