The WM_CAP_DLG_VIDEOCOMPRESSION message displays a dialog box in which the
user can select a compressor to use during the capture process. The list of
available compressors can vary with the video format selected in the capture driver's
Video Format dialog box. You can send this message explicitly or by using the capDlgVideoCompression
wParam = (WPARAM) 0;
lParam = 0L;
Returns TRUE if successful or FALSE otherwise.
Use this message with capture drivers that provide frames only in the BI_RGB
format. This message is most useful in the step capture operation to combine
capture and compression in a single operation. Compressing frames with a software
compressor as part of a real-time capture operation is most likely too
time-consuming to perform.
Compression does not affect the frames copied to the clipboard.
