IMFSample::ConvertToContiguousBuffer method (mfobjects.h)

  • Article

Converts a sample with multiple buffers into a sample with a single buffer.

Syntax

HRESULT ConvertToContiguousBuffer(
  [out] IMFMediaBuffer **ppBuffer
);

Parameters

[out] ppBuffer

Receives a pointer to the IMFMediaBuffer interface. The caller must release the interface.

Return value

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.
E_UNEXPECTED
 The sample does not contain any buffers.

Remarks

If the sample contains more than one buffer, this method copies the data from the original buffers into a new buffer, and replaces the original buffer list with the new buffer. The new buffer is returned in the ppBuffer parameter.

If the sample contains a single buffer, this method returns a pointer to the original buffer. In typical use, most samples do not contain multiple buffers.
