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. - -[ - object, - uuid(C6E13340-30AC-11d0-A18C-00A0C9118956), - pointer_default(unique) -] -interface IAMStreamConfig : IUnknown -{ - - // this is the structure returned by a VIDEO filter - // - typedef struct _VIDEO_STREAM_CONFIG_CAPS { - - GUID guid; // will be MEDIATYPE_Video - - // the logical or of all the AnalogVideoStandard's supported - // typically zero if not supported - ULONG VideoStandard; - - // the inherent size of the incoming signal... taken from the input - // pin for a compressor, or the largest size a capture filter can - // digitize the signal with every pixel still unique - SIZE InputSize; - - // The input of a compressor filter may have to be connected for these - // to be known - - // smallest rcSrc cropping rect allowed - SIZE MinCroppingSize; - // largest rcSrc cropping rect allowed - SIZE MaxCroppingSize; - // granularity of cropping size - eg only widths a multiple of 4 allowed - int CropGranularityX; - int CropGranularityY; - // alignment of cropping rect - eg rect must start on multiple of 4 - int CropAlignX; - int CropAlignY; - - // The input of a compressor filter may have to be connected for these - // to be known - - // smallest bitmap this pin can produce - SIZE MinOutputSize; - // largest bitmap this pin can produce - SIZE MaxOutputSize; - // granularity of output bitmap size - int OutputGranularityX; - int OutputGranularityY; - // !!! what about alignment of rcTarget inside BIH if different? - - // how well can you stretch in the x direction? 0==not at all - // 1=pixel doubling 2=interpolation(2 taps) 3=better interpolation - // etc. - int StretchTapsX; - int StretchTapsY; - // how well can you shrink in the x direction? 0==not at all - // 1=pixel doubling 2=interpolation(2 taps) 3=better interpolation - // etc. - int ShrinkTapsX; - int ShrinkTapsY; - - // CAPTURE filter only - what frame rates are allowed? - LONGLONG MinFrameInterval; - LONGLONG MaxFrameInterval; - - // what data rates can this pin produce? - LONG MinBitsPerSecond; - LONG MaxBitsPerSecond; - } VIDEO_STREAM_CONFIG_CAPS; - - - // this is the structure returned by an AUDIO filter - // - typedef struct _AUDIO_STREAM_CONFIG_CAPS { - - GUID guid; // will be MEDIATYPE_Audio - ULONG MinimumChannels; - ULONG MaximumChannels; - ULONG ChannelsGranularity; - ULONG MinimumBitsPerSample; - ULONG MaximumBitsPerSample; - ULONG BitsPerSampleGranularity; - ULONG MinimumSampleFrequency; - ULONG MaximumSampleFrequency; - ULONG SampleFrequencyGranularity; - } AUDIO_STREAM_CONFIG_CAPS; - - // - only allowed when pin is not streaming, else the call will FAIL - // - If your output pin is not yet connected, and you can - // connect your output pin with this media type, you should - // succeed the call, and start offering it first (enumerate as format#0) - // from GetMediaType so that this format will be used to connect with - // when you do connect to somebody - // - if your output pin is already connected, and you can provide this - // type, reconnect your pin.
