ISpStreamFormatConverter::ScaleConvertedToBaseOffset

ISpStreamFormatConverter::ScaleConvertedToBaseOffset maps a stream offset from the converted stream to the equivalent offset in the base stream.

<pre IsFakePre="true" xmlns="http://www.w3.org/1999/xhtml"> <strong>HRESULT ScaleConvertedToBaseOffset(</strong> <strong> ULONGLONG</strong> <em>ullOffsetConvertedStream</em>, <strong> ULONGLONG</strong> *<em>pullOffsetBaseStream</em> ); </pre>

Parameters

  • ullOffsetConvertedStream
    The offset of the output (converted) stream.
  • pullOffsetBaseStream
    The equivalent offset in the base (unconverted) stream.

Return Values

Value Description
S_OK Function completed successfully.
E_POINTER pullOffsetBaseStream is invalid.
SPERR_UNINITIALIZED The base stream has not been initialized.

Remarks

When performing a mapping with a compressed format, it is possible to introduce small rounding errors, since the content of the audio is not used to perform the conversion.
