UWP development details record: IStream and IRandomAccessStream ^ and IMFByteStream conversion, uwpistream

IStream and IRandomAccessStream ^ convert each other

IRandomAccessStream ^ --> IStream: CreateStreamOverRandomAccessStream

IStream --> IRandomAccessStream ^: CreateRandomAccessStreamOverStream

Mutual conversion between IStream and IMFByteStream

IStream --> IMFByteStream: MFCreateMFByteStreamOnStream

IMFByteStream --> IStream: MFCreateStreamOnMFByteStream

IMFByteStream andIRandomAccessStream ^ mutual conversion

IRandomAccessStream ^ --> IMFByteStream: MFCreateMFByteStreamOnStreamEx

IMFByteStream --> IRandomAccessStream ^: MFCreateStreamOnMFByteStreamEx

In addition:

The MFCreateMFByteStreamOnStreamEx MSDN document has an error. The first parameter should be IUnknown * rather than IUnknown;

Convert IRandomAccessStream ^ To IUnknown * use reinterpret_cast <IUnknown *> () or reinterpret_cast <IInspectable *> ().
