// IAMStreamConfig - pin interface

|
|
|
|
// 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.
