Then it configures the pin to use the smallest output size for that format. I could capture the image from webcam and save it as bitmap by using sampleGrabber. Unicorn Meta Zoo 9: How do we handle problem users?

Then you will set it and and connect it with downstream peer filters. SetFormat method iamstrdamconfig pass in the value of pmt. I placed it before RenderStream.
Email Required, but never shown. Active 1 iamstraemconfig, 5 months ago. For example, an audio pin might return a default media type of kHz, bit stereo in the pmt parameter. Post as a guest Name. Can someone help me, thanks so much!
For more information on implementing this method, see Exposing Capture and Compression Formats. Improving the question-asking experience. The pSCC parameter receives a structure that contains additional format information. This method returns two pieces of information: The following example retrieves the first supported format index zero on a video output pin. For brevity, this example shows only the case for UYVY format. For example, the graph below features three video capture devices and none of them has the dedicated preview pin: The caller must allocate the memory for the iamstreamclnfig parameter.
The method allocates the structure and fills it with a media type. Also, it assumes that the caller already knows the pin produces video output.

Here are some code below, thanks for your patient and help! FindInterface is powerful but it also adds chances to get into confusion.
The sample size depends partly on the bit depth, which can be determined from the media subtype. Iamstreamconig determine the required size of the array, call the GetNumberOfCapabilities method.
