IAMCopyCaptureFileProgress::Progress method (strmif.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The Progress method is called periodically by the ICaptureGraphBuilder2::CopyCaptureFile method while it copies the file.
Syntax

[in] int iProgress
);
Parameters
[in] iProgress
Specifies the percentage of the copy operation that has completed, as a value between 0 and 100.
Return value
Returns S_OK or an HRESULT error code.
Remarks
Applications typically use the value of iProgress to update a progress bar on the user interface.
