Stream Subtype GUIDs

下面的 subtype GUIDs 定义在 mfapi.h 头文件中。要设定这些 subtype，使用 MF_MT_SUBTYPE attribute。
当设置了这些 subtype 时，需要将 MF_MT_MAJOR_TYPE attribute 设为 MFMediaType_Stream。
| GUID | Description |
|---|---|
| MFStreamFormat_MPEG2Program | MPEG-2 program stream |
| MFStreamFormat_MPEG2Transport | MPEG-2 transport stream. |
Complete and Partial Media Types

此文介绍 complete media types 与 partial media types 的区别。
Complete Media Types
complete media 是完全定义媒体流格式的类型。给定完整的媒体类型，管道组件可以分析与媒体类型关联的流数据，而不会出现歧义。
对于未压缩的格式，以下主题定义了 complete media type 所需要的 attribute：
- Audio: Uncompressed Audio Media Types
- Video: Uncompressed Video Media Types
对于压缩过的 (或编码过) 的流，complete media type 的定义由编解码器定义。
Partial Media Types
partial media 缺少完整媒体类型所需的一个或多个属性。枚举可能的媒体类型时，Microsoft Media Foundation 组件可能会保留未设置的值，以指示它可以处理任何值。例如, 视频处理器可能会保留 MF_MT_FRAME_RATE attribute，以表示它可以处理任何帧速率，并在必要时执行帧速率转换。
如果创建 partial media type，则仍应包含所知道的尽可能多的信息。但是，不要包含不确定的信息。信息缺失总比错误好。
partial media type 至少应该包含这两个信息： MF_MT_MAJOR_TYPEand MF_MT_SUBTYPE。
有时候是必须使用 complete media types：
- Media sources 必须提供 complete output types.
- 解码器在设置 input type 之后必须提供 complete output types。在设置 input type 之前，解码器也许可以提供 partial output type。
- 编码器在设置 output type 之后必须提供 complete input types，在设置 output type 之前，编码器也许可以提供 partial input type。
Media Type Conversions

有时需要在 Media Foundation media types 和更老的 DirectShow 或 Windows Media Format SDK 里的 media type 结构之间进行转换。
From a Format Structure to a Media Foundation Type
下面的函数使用一个 format structure 来初始化 Media Foundation media type。当数据流或者文件头包含有 format structure 时也可以使用这些函数。例如 WAVE 音频文件开头就包含一个 WAVEFORMATEX 结构体。
| Structure to Convert | Function |
|---|---|
|
AM_MEDIA_TYPE (DirectShow) DMO_MEDIA_TYPE (DirectX Media Objects) WM_MEDIA_TYPE (Windows Media Format SDK)
|
MFInitMediaTypeFromAMMediaType |
| BITMAPINFOHEADER | MFCreateVideoMediaTypeFromBitMapInfoHeaderEx |
| MFVIDEOFORMAT | MFInitMediaTypeFromMFVideoFormat |
| MPEG1VIDEOINFO | MFInitMediaTypeFromMPEG1VideoInfo |
| MPEG2VIDEOINFO | MFInitMediaTypeFromMPEG2VideoInfo |
| VIDEOINFOHEADER2 | MFInitMediaTypeFromVideoInfoHeader2 |
| VIDEOINFOHEADER | MFInitMediaTypeFromVideoInfoHeader |
| WAVEFORMATEX or WAVEFORMATEXTENSIBLE | MFInitMediaTypeFromWaveFormatEx |
From a Media Foundation Type to a Format Structure
下面的函数使用 Media Foundation media type 来创建或者初始化一个 format structure。
| Function | Target Structure |
|---|---|
| IMFMediaType::GetRepresentation | AM_MEDIA_TYPE, MFVIDEOFORMAT, VIDEOINFOHEADER, or VIDEOINFOHEADER2 |
| MFCreateAMMediaTypeFromMFMediaType | AM_MEDIA_TYPE |
| MFCreateMFVideoFormatFromMFMediaType | MFVIDEOFORMAT |
| MFCreateWaveFormatExFromMFMediaType | WAVEFORMATEX or WAVEFORMATEXTENSIBLE |
| MFInitAMMediaTypeFromMFMediaType | AM_MEDIA_TYPE |
Format Mappings
下表列出了 Media Foundation attributes 与对应的 format structure 属性。并非所有的这些属性都可以直接转换。若要执行转换，参考上一节列出的函数。这个表格仅供参考。
AM_MEDIA_TYPE
| Member | Attribute |
|---|---|
| bTemporalCompression | MF_MT_ALL_SAMPLES_INDEPENDENT |
| bFixedSizeSamples | MF_MT_FIXED_SIZE_SAMPLES |
| lSampleSize | MF_MT_SAMPLE_SIZE |
WAVEFORMATEX, WAVEFORMATEXTENSIBLE
| Member | Attribute |
|---|---|
| wFormatTag |
MF_MT_SUBTYPE If wFormatTag is WAVE_FORMAT_EXTENSIBLE, the subtype is found in the SubFormat member. |
| nChannels | MF_MT_AUDIO_NUM_CHANNELS |
| nSamplesPerSec | MF_MT_AUDIO_SAMPLES_PER_SECOND |
| nAvgBytesPerSec | MF_MT_AUDIO_AVG_BYTES_PER_SECOND |
| nBlockAlign | MF_MT_AUDIO_BLOCK_ALIGNMENT |
| wBitsPerSample | MF_MT_AUDIO_BITS_PER_SAMPLE |
| wValidBitsPerSample | MF_MT_AUDIO_VALID_BITS_PER_SAMPLE |
| wSamplesPerBlock | MF_MT_AUDIO_SAMPLES_PER_BLOCK |
| dwChannelMask | MF_MT_AUDIO_CHANNEL_MASK |
| SubFormat | MF_MT_SUBTYPE |
| Extra data | MF_MT_USER_DATA |
VIDEOINFOHEADER, VIDEOINFOHEADER2
| Member | Attribute |
|---|---|
| dwBitRate | MF_MT_AVG_BITRATE |
| dwBitErrorRate | MF_MT_AVG_BIT_ERROR_RATE |
| AvgTimePerFrame | MF_MT_FRAME_RATE; use MFAverageTimePerFrameToFrameRateto calculate this value. |
| dwInterlaceFlags | MF_MT_INTERLACE_MODE |
| dwCopyProtectFlags | No defined equivalent |
| dwPictAspectRatioX, dwPictAspectRatioY | MF_MT_PIXEL_ASPECT_RATIO; must convert from picture aspect ratio to picture aspect ratio. |
| dwControlFlags | MF_MT_PAD_CONTROL_FLAGS. If the AMCONTROL_COLORINFO_PRESENT flag is present, set the extended color attributes described in Extended Color Information. |
| bmiHeader.biWidth, bmiHeader.biHeight | MF_MT_FRAME_SIZE |
| bmiHeader.biBitCount | Implicit in the subtype (MF_MT_SUBTYPE). |
| bmiHeader.biCompression | Implicit in the subtype. |
| bmiHeader.biSizeImage | MF_MT_SAMPLE_SIZE |
| Palette information | MF_MT_PALETTE |
下面的属性可以从 VIDEOINFOHEADER 或 VIDEOINFOHEADER2 结构推断出来，但是这要求对格式细节有一定的了解。例如不同的 YUV 格式有不同的 stride。
- MF_MT_DEFAULT_STRIDE
- MF_MT_MINIMUM_DISPLAY_APERTURE
- MF_MT_PAN_SCAN_APERTURE
MPEG1VIDEOINFO
| Member | Attribute |
|---|---|
| dwStartTimeCode | MF_MT_MPEG_START_TIME_CODE |
| bSequenceHeader | MF_MT_MPEG_SEQUENCE_HEADER |
| biXPelsPerMeter, biYPelsPerMeter | MF_MT_PIXEL_ASPECT_RATIO |
MPEG2VIDEOINFO
| Member | Attribute |
|---|---|
| dwStartTimeCode | MF_MT_MPEG_START_TIME_CODE |
| dwSequenceHeader | MF_MT_MPEG_SEQUENCE_HEADER |
| dwProfile | MF_MT_MPEG2_PROFILE |
| dwLevel | MF_MT_MPEG2_LEVEL |
| dwFlags | MF_MT_MPEG2_FLAGS |
Examples
下面的代码使用一个 video media type，补充了一个 BITMAPINFOHEADER。注意这个转换丢掉了一些信息（隔行扫描，帧率，扩展颜色数据），然而在从视频帧保存成位图时，可能需要这些信息。
