The ICINFO structure is filled by a video compression driver when it receives the ICM_GETINFO message.

Members

dwSize

Should be set to the size of the ICINFO structure.

fccType

Specifies a four-character code representing the type of stream being compressed or decompressed. Set this to ‘vidc’ for video streams.

fccHandler

Specifies a four-character code identifying a specific compressor.

dwFlags

Specifies any flags. The following flags are defined for video compressors:

Flag	Meaning
VIDCF_QUALITY	Indicates the driver supports quality values.
VIDCF_CRUNCH	Indicates the driver supports crunching to a frame size.
VIDCF_TEMPORAL	Indicates the driver supports interframe compression.
VIDCF_DRAW	Indicates the driver supports drawing.
VIDCF_FASTTEMPORALC	Indicates the driver can do temporal compression and doesn’t need the previous frame.
VIDCF_FASTTEMPORALD	Indicates the driver can do temporal decompression and doesn’t need the previous frame.
VIDCF_COMPRESSFRAMES	Indicates the driver wants the “compress all frames” message.

dwVersion

Specifies the version number of the driver.

dwVersionICM

Specifies the version of the ICM supported by this driver; it should be set to ICVERSION.

szName[16]

Specifies the short name for the compressor. The name in the zero-terminated string should be suitable for use in list boxes.

szDescription[128]

Specifies a zero-terminated string containing the long name for the compressor.

szDriver[128]

Specifies a zero-terminated string for the module that contains the driver. Typically, a driver will not need to fill this out.
