ICCompressGetFormat macro (vfw.h)

The ICCompressGetFormat macro requests the output format of the compressed data from a video compression driver. You can use this macro or explicitly call the ICM_COMPRESS_GET_FORMAT message.

Syntax

DWORD ICCompressGetFormat(
     hic,
     lpbiInput,
     lpbiOutput
);

Parameters

hic

Handle of the compressor.

lpbiInput

Pointer to a BITMAPINFO structure containing the input format.

lpbiOutput

Pointer to a BITMAPINFO structure containing the output format.

Return value

Type: DWORD

If lpbiOutput is zero, returns the size of the structure. If lpbiOutput is nonzero, returns ICERR_OK if successful or an error otherwise.

Remarks

If lpbiOutput is nonzero, the driver should fill the BITMAPINFO structure with the default output format corresponding to the input format specified for lpbiInput. If the compressor can produce several formats, the default format should be the one that preserves the greatest amount of information.
