The ICSeqCompressFrame function compresses one frame in a sequence of frames.
LPVOID ICSeqCompressFrame(
PCOMPVARS pc,
UINT uiFlags,
LPVOID lpBits,
BOOL * pfKey,
LONG * plSize
);
Returns the address of the compressed bits if successful or NULL otherwise.
This function uses a COMPVARS structure to provide settings for the specified compressor and intersperses key frames at the rate specified by the ICSeqCompressorFrameStart function. You can specify values for the data rate for the sequence and the key-frame frequency by using the appropriate members of COMPVARS.
Use this function instead of the ICCompress function to compress a video sequence.
You can allow the user to specify a compressor and initialize a COMPVARS structure by using the ICCompressorChoose function. Or, you can initialize a COMPVARS structure manually.
Use the ICSeqCompressFrameStart, ICSeqCompressFrame, and ICSeqCompressFrameEnd functions to compress a sequence of frames to a specified data rate and number of key frames. Use ICSeqCompressFrame once for each frame to be compressed.
When finished with compression, use the ICCompressorFree function to release the resources specified by COMPVARS.
