WM_CAP_DLG_VIDEOCOMPRESSION
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 macro.
WM_CAP_DLG_VIDEOCOMPRESSION
wParam = (WPARAM) 0;
lParam = 0L;
Return Values
Returns TRUE
if successful or FALSE otherwise.
Remarks
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.
