ICDecompress

The ICDecompress function decompresses a single video frame.

DWORD ICDecompress(

HIC hic,
DWORD dwFlags,
LPBITMAPINFOHEADER lpbiFormat,
LPVOID lpData,
LPBITMAPINFOHEADER lpbi,
LPVOID lpBits
);

Parameters
hic

Handle of the decompressor to use.

dwFlags

Applicable decompression flags. The following values are defined:

ICDECOMPRESS_HURRYUP

Tries to decompress at a faster rate. When an application uses this flag, the driver should buffer the decompressed data but not draw the image.

ICDECOMPRESS_NOTKEYFRAME

Current frame is not a key frame.

ICDECOMPRESS_NULLFRAME

Current frame does not contain data and the decompressed image should be left the same.

ICDECOMPRESS_PREROLL

Current frame precedes the point in the movie where playback starts and, therefore, will not be drawn.

ICDECOMPRESS_UPDATE

Screen is being updated or refreshed.

lpbiFormat

Address of a BITMAPINFO structure containing the format of the compressed data.

lpData

Address of the input data.

lpbi

Address of a BITMAPINFO structure containing the output format.

lpBits

Address of a buffer that is large enough to contain the decompressed data.

Return Values
Returns ICERR_OK if successful or an error otherwise.
