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.
