//

// A capture filter or compression filter's output pin
// supports this interface - no matter what data type you produce.

// This interface can be used to set the output format of a pin (as an
// alternative to connecting the pin using a specific media type).
// After setting an output format, the pin will use that format
// the next time it connects to somebody, so you can just Render that
// pin and get a desired format without using Connect(CMediaType)
// Your pin should do that by ONLY OFFERING the media type set in SetFormat
// in its enumeration of media types, and no others.  This will ensure that
// that format is indeed used for connection (or at least offer it first).
// An application interested in enumerating accepted mediatypes may have to
// do so BEFORE calling SetFormat.

// But this interface's GetStreamCaps function can get more information
// about accepted media types than the traditional way of enumerating a pin's
// media types, so it should typically be used instead.
// GetStreamCaps gets information about the kinds of formats allowed... how
// it can stretch and crop, and the frame rate and data rates allowed (for
// video)

// VIDEO EXAMPLE
//
// GetStreamCaps returns a whole array of {MediaType, Capabilities}.
// Let's say your capture card supports JPEG anywhere between 160x120 and
// 320x240, and also the size 640x480.  Also, say it supports RGB24 at
// resolutions between 160x120 and 320x240 but only multiples of 8.  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.  Let's say you
// do any PCM frequency from 11,025 to 44,100 at 8 or 16 bit mono or
// stereo, and you also do 48,000 16bit stereo as a special combination.
// You would expose 3 pairs.  The first pair would have Min Freq of 11025 and
// Max Freq of 44100, with MaxChannels=2 and MinBits=8 and MaxBits=8 for the
// capabilites structure, and a media type of anything you like, maybe
// 22kHz, 8bit stereo as a default.
// The 2nd pair would be the same except for MinBits=16 and MaxBits=16 in
// the capabilities structure and the media type could be something like
// 44kHz, 16bit stereo as a default (the media type in the pair should always
// be something legal as described by the capabilities structure... the
// structure tells you how you can change the media type to produce other
// legal media types... for instance changing 44kHz to 29010Hz would be legal,
// but changing bits from 16 to 14 would not be.)
// The 3rd pair would be MinFreq=48000 MaxFreq=48000 MaxChannels=2
// MinBits=16 and MaxBits=16, and the media type would be 48kHz 16bit stereo.
// You can also use the Granularity elements of the structure (like the example
// for video) if you support values that multiples of n, eg.  you could say
// minimum bits per sample 8, max 16, and granularity 8 to describe doing
// either 8 or 16 bit all in one structure
//
// If you support non-PCM formats, the media type returned in GetStreamCaps
// can show which non-PCM formats you support (with a default sample rate,
// bit rate and channels) and the capabilities structure going with that
// media type can describe which other sample rates, bit rates and channels
// you support.
