ICSeqCompressFrameStart
The ICSeqCompressFrameStart function initializes resources for compressing a sequence of frames using the ICSeqCompressFrame function.
BOOL ICSeqCompressFrameStart(
PCOMPVARS pc,
|
| LPBITMAPINFO lpbiIn
|
| );
|
|
Parameters
pc
Address of a COMPVARS structure initialized with information for compression.
lpbiIn
Format of the data to be compressed.
Return Values
Returns TRUE if successful or FALSE otherwise.
Remarks
This function uses a COMPVARS structure to provide settings for the specified compressor and intersperses
key frames at the rate specified by the lKey member of COMPVARS. You can specify values for the data rate for the sequence and the key-frame
frequency by using the appropriate members of COMPVARS.
Use the ICSeqCompressFrameStart, ICSeqCompressFrame, and ICSeqCompressFrameEnd functions to compress a sequence of frames to a specified data rate and
number of key frames.
When finished with compression, use the ICCompressorFree function to release the resources specified in COMPVARS.
COMPVARS needs to be initialized before you use this function. You can initialize the
structure manually or you can allow the user to specify a compressor and
initialize a COMPVARS structure by using the ICCompressorChoose function.
