You would +// expose these properties by offering a media type of 320 x 240 JPEG +// (if that is your default or preferred size) coupled with +// capabilities saying minimum 160x120 and maximum 320x240 with granularity of +// 1. The next pair you expose is a media type of 640x480 JPEG coupled with +// capabilities of min 640x480 max 640x480. The third pair is media type +// 320x240 RGB24 with capabilities min 160x120 max 320x240 granularity 8. +// In this way you can expose almost every quirk your card might have. +// An application interested in knowing what compression formats you provide +// can get all the pairs and make a list of all the unique sub types of the +// media types. +// +// If a filter's output pin is connected with a media type that has rcSource +// and rcTarget not empty, it means the filter is being asked to stretch the +// rcSource sub-rectangle of its InputSize (the format of the input pin for +// a compressor, and the largest bitmap a capture filter can generate with +// every pixel unique) into the rcTarget sub-rectangle of its output format. +// For instance, if a video compressor has as input 160x120 RGB, and as output +// 320x240 MPEG with an rcSource of (10,10,20,20) and rcTarget of (0,0,100,100) +// this means the compressor is being asked to take a 10x10 piece of the 160x120 +// RGB bitmap, and make it fill the top 100x100 area of a 320x240 bitmap, +// leaving the rest of the 320x240 bitmap untouched. +// A filter does not have to support this and can fail to connect with a +// media type where rcSource and rcTarget are not empty. +// +// Your output pin is connected to the next filter with a certain media +// type (either directly or using the media type passed by SetFormat), +// and you need to look at the AvgBytesPerSecond field of the format +// of that mediatype to see what data rate you are being asked to compress +// the video to, and use that data rate. Using the number of frames per +// second in AvgTimePerFrame, you can figure out how many bytes each frame +// is supposed to be. You can make it smaller, but NEVER EVER make a bigger +// data rate. For a video compressor, your input pin's media type tells you +// the frame rate (use that AvgTimePerFrame). For a capture filter, the +// output media type tells you, so use that AvgTimePerFrame. +// +// The cropping rectangle described below is the same as the rcSrc of the +// output pin's media type. +// +// The output rectangle described below is the same of the width and height +// of the BITMAPINFOHEADER of the media type of the output pin's media type + + +// AUDIO EXAMPLE +// +// This API can return an array of pairs of (media type, capabilities). +// This can be used to expose all kinds of wierd capabilities.
