下列範例會壓縮影像數據,以用於 AVI 檔案。 它假設壓縮機不支援VIDCF_CRUNCH或VIDCF_TEMPORAL旗標,但它確實支援VIDCF_QUALITY。 此範例使用 ICCompressBegin 巨集(macro)、ICCompress 函式,以及 ICCompressEnd 巨集(macro)。
DWORD dwCkID;
DWORD dwCompFlags;
DWORD dwQuality;
LONG lNumFrames, lFrameNum;
// Assume dwNumFrames is initialized to the total number of frames.
// Assume dwQuality holds the proper quality value (0-10000).
// Assume lpbiOut, lpOut, lpbiIn, and lpIn are initialized properly.
// If OK to start, compress each frame.
if (ICCompressBegin(hIC, lpbiIn, lpbiOut) == ICERR_OK)
{
for ( lFrameNum = 0; lFrameNum < lNumFrames; lFrameNum++)
{
if (ICCompress(hIC, 0, lpbiOut, lpOut, lpbiIn, lpIn,
&dwCkID, &dwCompFlags, lFrameNum,
0, dwQuality, NULL, NULL) == ICERR_OK)
{
// Write compressed data to the AVI file.
// Set lpIn to the next frame in the sequence.
}
else
{
// Handle compressor error.
}
}
ICCompressEnd(hIC); // terminate compression
}
else
{
// Handle the error identifying the unsupported format.
