IMFMediaSource::CreatePresentationDescriptor method

Retrieves a copy of the media source's presentation descriptor. Applications use the presentation descriptor to select streams and to get information about the source content.

Syntax

HRESULT CreatePresentationDescriptor(
  IMFPresentationDescriptor **ppPresentationDescriptor
);

Parameters

ppPresentationDescriptor

Receives a pointer to the presentation descriptor's IMFPresentationDescriptor interface. The caller must release the interface.

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
The method succeeded.
MF_E_SHUTDOWN
The media source's Shutdown method has been called.

Remarks

The presentation descriptor contains the media source's default settings for the presentation. The application can change these settings by selecting or deselecting streams, or by changing the media type on a stream. Do not modify the presentation descriptor unless the source is stopped. The changes take affect when the source's IMFMediaSource::Start method is called.
