GetXmaDecodePositionForSample
Obtains data needed to make the decoder generate audio starting at a specified sample position relative to the beginning of the specified XBOX Media Audio (XMA) block.Syntax
Parameters
pXmaData _In_bytecount_(nXmaDataBytes)Type: BYTE* Pointer to XMA blocks. nXmaDataBytes
Type: DWORD Size of pXmaData, in bytes. nStreamIndex
Type: DWORD Stream within which to seek. nDesiredSample
Type: DWORD Sample sought. pnBitOffset _Out_
Type: DWORD* Returns the bit offset within pXmaData of the frame that contains the sample sought. pnSubFrame _Out_
Type: DWORD* Returns the subframe that contains the sample.
Return value
Type: HRESULT SuccessS_OK or error E_FAIL code.
Remarks
This function obtains data needed to make the decoder generate audio starting at a given sample position relative to the beginning of the given XMA block. This includes the bit offset of the appropriate frame and the right subframe within that frame. The data can be passed directly to theXMAPlaybackSetDecodePosition function.
