CS_CompressionCaps (Windows Embedded CE 6.0)
1/6/2010
This enumeration provides values that are used to describe compression capabilities of a device.
Syntax
typedef enum {
CS_CompressionCaps_CanQuality = 1,
CS_CompressionCaps_CanCrunch = 2,
CS_CompressionCaps_CanKeyFrame = 4,
CS_CompressionCaps_CanBFrame = 8,
CS_CompressionCaps_CanWindow = 0x10,
} CS_CompressionCaps;
Elements
- CS_CompressionCaps_CanQuality
Indicates that the video compressor supports quality settings.
- CS_CompressionCaps_CanCrunch
Indicates that the video compressor can compress the video to a specified data rate. If a minidriver supports this capability, the dwBitRate member of the CS_VIDEOINFOHEADER structure contains the default data rate.
- CS_CompressionCaps_CanKeyFrame
Indicates that the video compressor supports a user-specified key-frame rate.
- CS_CompressionCaps_CanBFrame
Indicates that the video compressor supports a user-specified P frame interval. The frames that occur between the key frames and P frames are bidirectional (B) frames.
- CS_CompressionCaps_CanWindow
Indicates that the video compressor supports a user-specified window size (number of frames whose average size cannot exceed the specified data rate).
