IVPBaseConfig::GetMaxPixelRate method (vpconfig.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetMaxPixelRate method retrieves the maximum pixel rate the device will output for a given width and height.
Syntax

[in, out] LPAMVPSIZE pamvpSize,
[out] LPDWORD pdwMaxPixelsPerSecond
);
Parameters
[in, out] pamvpSize
Pointer to an AMVPSIZE structure containing the desired width and height.
[out] pdwMaxPixelsPerSecond
Pointer to a variable that receives the maximum pixel rate, in pixels per second.
