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.
interface IMFByteStream : public IUnknown
The following functions return IMFByteStream pointers for local files:
A byte stream for a media souce can be opened with read access. A byte stream for an archive media sink should be opened with both read and write access. (Read access may be required, because the archive sink might need to read portions of the file as it writes.)
Some implementations of this interface also expose one or more of the following interfaces:
Header: Declared in mfobjects.h (include mfidl.h).
Library: Use Mfuuid.lib.
