How to read the content of the PropertyPage?

[Reve]

A click on a filter's output pin brings up the property page with info like
this:


Video Properties
***********************
Video (Tab)
-----------
Major Type: Video

Sub Type: RGB24
Format: YUV 360x-240, 12 bits
reSrc={8,0,360,240}
rcDst{0,0,0,0}
=====================


How to read the text above from application? ISpecifyPropertyPages doesn't
work for me.

You have to get the ConnectionMediaType from the output pin itself.
If you only have a reference to the filter, use findpin or enumerate
the pins to get the output pin.

e.g.

IPin pin = DsFindPin.ByDirection(filter, PinDirection.Input, 0);

hr = pin.ConnectionMediaType(pmt);
DsError.ThrowExceptionForHR(hr);

if (pmt.formatType == FormatType.VideoInfo2)
{
VideoInfoHeader2 vih2 = (VideoInfoHeader2)Marshal.PtrToStructure
(pmt.formatPtr, typeof(VideoInfoHeader2));
}
else if (pmt.formatType == FormatType.VideoInfo)
{
VideoInfoHeader vih = (VideoInfoHeader)Marshal.PtrToStructure
(pmt.formatPtr, typeof(VideoInfoHeader));
}
