Video Subtype GUIDs

The following video subtype GUIDs are defined in the header file mfapi.h. To specify the subtype, set the MF_MT_SUBTYPE attribute on the media type.

When these subtypes are used, set the MF_MT_MAJOR_TYPE attribute to MFMediaType_Video.

Uncompressed RGB Formats

Creating Subtype GUIDs from FOURCCs and D3DFORMAT Values

Video formats are often represented by FOURCCs or D3DFORMAT values. A range of GUIDs is reserved for representing these values as subtypes. These GUIDs have the form XXXXXXXX-0000-0010-8000-00AA00389B71, where XXXXXXXX is the 4-byte FOURCC code or D3DFORMAT value.

If a video format has an associated FOURCC or D3DFORMAT value, you can create the corresponding subtype GUID as follows: Start with the constant MFVideoFormat_Base and replace the first DWORD of the GUID with the video FOURCC or the D3DFORMAT value. You can use the DEFINE_MEDIATYPE_GUID macro for this purpose.

Note

DirectShow also uses this system for most video subtypes, but not for uncompressed RGB formats. Therefore, the RGB subtypes in DirectShow do not match the RGB subtypes in Media Foundation.

 

The D3DFORMAT enumeration is defined in the header file d3d9types.h. The following table shows the most common uncompressed RGB formats and the corresponding D3DFORMAT value.

RGB format D3DFORMAT value
32-bit RGB D3DFMT_X8R8G8B8
32-bit RGB with alpha channel D3DFMT_A8R8G8B8
24-bit RGB D3DFMT_R8G8B8

RGB 555 with alpha channel D3DFMT_A4R4G4B4
RGB 565 (16-bit RGB) D3DFMT_R5G6B5

A2 R10 G10 B10 (32-bit RGB with alpha channel; 10 bits per RGB channel) D3DFMT_A2R10G10B10
A2 B10 G10 R10 (32-bit RGB with alpha channel; 10 bits per RGB channel) D3DFMT_A2B10G10R10
